4 Cycle Product News

VENT TUBE EXTENSION

The Series “8” carburetor used on many LEV and OVRM

series engines has a new extension tube added to the

atmospheric vent passage. This tube part number 632766

was added to stabilize the atmospheric pressure in the

bowl, improving the run quality. This was done in

combination with carburetor calibration changes. This

tube is serviceable and must be installed to a precise

depth using tool part number 670343 to maintain emission

standards and prevent blockage of the atmospheric vent

passage. Do not use this tube on applications that it

was not originally on. Always verify that the engine

requires this tube by checking the parts list.

COLD START HANG TAG

Tecumseh has gone through extensive efforts to educate

the customer in the proper procedures used to prime

today’s emissions engine. If a customer comments about

an engine that is hard to start, it may be helpful to ask

them to demonstrate the method they use when priming.

In most cases there is not any engine problem and we

have found improper priming is the cause. Most recently

we have created a hang tag with instructions on the

“Thumbs Up” five prime technique. This cold start

procedure is outlined in the owners manuals and is

illustrated by the use of a decal on the blower housing

or fuel tank on some engines. It requires that the thumb

be used to prime because the thumbs larger surface

area covers the primer bulb better. Remember always

to wait two seconds between primes.

HOW THE NEW EMISSIONS PRIMER WORKS

The primer used on emission grade carburetors has

been designed to provide the precise amount of fuel

being delivered with each compression. This style of

primer must squarely make contact with the inside casting

surface of the carburetor before any prime occurs. This

will prevent air from being forced back into the air filter

and send the prime charge into the carburetor. A brief

delay of two seconds between each prime will assure

that the primer has recovered ample air to provide an

adequate prime charge.

LEV/VLV VALVE STEM SEAL CHANGE

A design change has been made to the intake valve

stem seal used on LEV and VLV engines. The seal

area which makes contact with the casting surface in

the valve box has been enlarged to improve sealing. A

better seal on the valve stem will allow the elimination

of an o-ring that had been used on engines prior to

this. We have also reissued Service Bulletin “406” which

references kit number 730617 to include the new seal.

Removal of the intake valve may cause damage to the

seal, always install a new seal when this type of repair

work is done.

VLV AIR BAFFLE CHANGE

The fiber baffle/gasket used between the carburetor

and cylinder block on the VLV engine has been changed

to a metal baffle. A gasket is used on each side of the

metal baffle which replaces the fiber gasket (an

instruction sheet is included for installation). This baffle

allows for cooler running carburetor bowl temperatures

eliminating the occasional carburetor popping during

high ambient temperature operation. We also created

a bendable high speed adjustment tab as part of the

baffle for fixed speed applications. Speed adjustments

if necessary are done by bending the tab to the right to

increase speed and to the left to decrease speed.

SERIES 11 CARBURETOR

This is possibly the most innovative and exciting primer

type carburetor to be introduced since emissions

standards were established. The series “11” carburetor

is being released in limited quantities this year. Its design

helps to eliminate the cold blooded nature of emissions

engines by drawing fuel from a reservoir during the

first minute of operation giving it smoother start up and

warm up characteristics. This will give the engines using

this carburetor the personality of one built prior to the

emissions standards. The external physical package

is identical to that of a series "8" carburetor. Removing

the bowl will expose the welch plug used to cover the

extended prime fuel chamber. There is also an additional

passage way along side the center leg which feeds

the fuel into this chamber when the carburetor is primed.

During start up operation, the fuel is drawn from this

chamber into the venturi until the chamber is empty, at

which time normal operation is resumed. When cleaning

an emissions carburetor remember the passages are

extremely small. The best method for cleaning this

carburetor is to remove all welch plugs and use

carburetor cleaner and compressed air to clean the

passages. It is not recommended to soak the carburetor

in carburetor cleaner.

VLV NO BOTTOM DRAIN FLANGE

The VLV engine now has an option available to OEM’s

with no oil drain on the bottom of the mounting flange.

This will be available for applications such as generators,

pumps and pressure washers. In place of the bottom

drain there is an optional side drain. If an OEM would

choose to use this flange on a rotary lawnmower

application, removing the oil may be accomplished by

draining the oil out of the fill tube. This flange has been

available since July 1998.

HM CLIMATE GUARD™ KIT

Climate Guard™ for HM engines is available on original

equipment and will be used exclusively on Generac

product for 1999. However, there is now a kit available

for existing engines. If you have emissions or non-

emissions engines that are used during both summer

and winter seasons, you can now convert it to the Climate

Guard™ system by using part number 730630. Typical

applications that could use this system are log splitters

and generators.

LEV 80 NEW OFFERING

The LEV 80 is a new 3.5 hp engine being offered this

year. It has been designed using the technology

developed in the LEV engine with the straight valve

train used in the TVS engines. This engine has the

same cylinder fin design and flow through valve cooling

system that allows the LEV to run at reduced cylinder

block temperatures. It is being used on opening price

point units and puts an offering in the market place

that has the quality, and durability of the higher price

units.

TORO FUEL TANK BAFFLE

The OHSK 120 used on Toro snow throwers has a foam

baffle added to the fuel tank. This will prevent splashing

and inconsistent fuel flow when there is less then an

inch of fuel inside the tank. The foam baffle stabilizes

the fuel supply to prevent the occasional fuel starvation

situation. The material is similar to that used in race

car fuel cells and is impervious to all of today’s fuels

within our standard fuel guidelines. The part number

for the complete tank assembly is 37290.

OHH 7 AMP D.C. CHARGING SYSTEM

This series of engines has quickly become one of the

most popular engines in the industry. It is now poised

to expand into markets that require a higher output

charging system. A 7 Amp D.C. charging system is

now available on OHH/OHSK 50-70 model engines.

This reliable compact power plant can now be applied

to those applications that require higher battery starting

capabilities. The alternator part number is 611233.

Upgrading existing equipment will require that the

flywheel be changed to accommodate the alternator

which uses internal magnets.

220 VOLT STARTERS

There is now a 220 volt 50 hertz starter available for

countries outside the US and Canada. These starters,

part number 37102 (H30-35, HS40-50, HSK34, HSSK40-

50, OHSK50-70) and 37217 (HM70-100, HMSK70-100,

OHSK80-120) have only a limited number of parts that

are serviceable due to European Community regulation.

None of the internal parts can be serviced. Only the

parts from the engagement nut to the cap are serviceable

externally. The starter does not include a power cord

because of the multiple options used in different

countries.

DIPSTICK COUNTER BORE OHH

On many applications the OHH engine uses a dipstick

gauge that threads directly into the cylinder cover.

Checking the oil has been a challenge at times because

of difficulty reinstalling the oil gauge without cross

threading. This situation has been corrected by

machining a counter bore in the oil gauge hole and

adding a 45° chamfer to the lead in thread making

reinstallation easier. Remember to instruct the

customer to clean the area around the dipstick prior

to removal.

ONE CONNECTING ROD FOR ALL

In our continuing effort to reduce the inventory required

to service our engines, a change has occurred to the

small frame connecting rod. When you order connecting

rod part number 32875A, you will receive an instruction

sheet explaining which oil dipper, if any, is used. An

example is the H30-HS50 which uses dipper number

32654. The same connecting rod is used on small

frame overhead valve engines but uses the longer 36611

dipper. Please follow the instruction sheet carefully.

Remember always assemble the rod and cap with the

match marks facing out.

FLYMO REPLACEMENTS AVAILABLE

There are now Service Replacement Engines available

for the Flymo hover mower application. They are available

in all states with the exception of California. These engines

are able to meet the E.P.A. emissions standards for

hand-held equipment through use of a fixed jet carburetor

and cylinder port timing changes. The engines will be

available in early 1999, under service part number’s 800175

and 800176. Please consult your parts lookup system

or the service engine specification book to locate the

correct one.

EMISSIONIZED AV520/600

The AV series engines used on post hole diggers and

ice augers has been changed in several areas to meet

the E.P.A. emissions regulations for hand-held product.

These improvements include changes to cylinder port

timing and the carburetor being made customer tamper-

proof. The carburetor changes involve fixed jets in both

the idle and high speed circuits. The idle restrictor jet

can be removed for service but the idle restrictor cap

(640053) must be re-installed to maintain compliance.

All fixed jets that screw in seal against the taper, it is

critical that you do not over tighten the jet when re-installing

or damage to the metering hole will occur. Tighten to

5-8 inch lbs. (.5-1.0 NM)

MST LEAKING AXLE SEALS

Last year we advised you of the running change made

to the axle seals used on all MST Series transaxles to

improve sealing. We still hear about the occasional

seal leakage on some MST’s. Our evaluations have

found that when the unit was serviced and then re-

assembled the old seals were re-used with sealant

placed around the perimeter of the seal. This sealant

will get into the seal spring, harden and cause it to not

function properly and leak. Always replace the seals if

the transmission is serviced and DO NOT use sealant

in the seal pockets. When re-assembly is complete we

recommend a low pressure leak down testing of the

unit. The test pressure must not exceed 15 PSI (1 Bar)

or seal damage will occur. We have developed a test

kit part number 670345 as an add on for an existing

leak down tester or our complete kit 670340. Both

are available from your normal supplier.

NEW MST SERVICE VIDEO 696250

820 SERIES SEALANT

The 820 series transaxle has been changed from Loctite

515 Gasket Eliminator to Loctite Ultra Gray RTV Silicone,

Tecumseh Part Number 788093A. This change improves

the perimeter seal reducing the chance of water entering

the case during cleaning by the operator. When service

is needed on older models, please re-seal the case

using the Loctite Ultra Gray RTV which is resistant to

oil and grease.

NEW VST SERIES PULLER

The directional control arm on the VST205 hydrostatic

series transaxle is attached using a tapered shaft or

taper and key combination and then secured with a

nut and lock washer. Should this arm need to be

removed, a puller is required. Removal without using

a puller can severely damage the internal parts of the

transaxle, which is not repairable, causing replacement

of the entire assembly. We have developed a special

puller, Tecumseh Part Number 670342 to remove this

arm. When the control arm is re-installed on the unit,

it must be tightened in the neutral position, the nut is

torqued to 25 to 30 ft. lbs. (33.9 - 40.7 Nm). Should

you still have questions consult the 691218 Motion Drives

Technician's Handbook.

1310 SERIES AXLES 1 1/8

At the request of the Toro Company, we have increased

the axle diameter of their 1310 series unit to 1-1/8 inches.

This diameter change increases the durability of this

model for their application. Service replacements for

this model have been upgraded to this new axle diameter

as well.

NEW EXTERNAL SNUBBER FORCE

ADJUSTMENT BULLETIN 308

We have issued Service Bulletin 308 to review a change

made to the “C” versions of the VST series transaxle

(example VST205-024C) This bulletin outlines the

adjustment of the shift force required to move the control

lever. Never automatically assume the hydro is the

problem, our evaluations of several units returned found

no defect at all. In these situations we found a slipping

belt (extremely glazed) from low tension to be the

problem.

The bulletin outlines first cleaning the unit then the

procedure for removing an access plug and adjusting

the snubber screw which controls the shifting forces.

You should NEVER need to turn the screw more than

one turn. If you turn beyond this limit, the screw could

come out of the case, this screw cannot be re-installed

in the field and will require complete unit replacement.

Please use extreme caution if performing this procedure

and follow the bulletin exactly.

Service Tips

LEV WIDER VALVE SEATS

The valve seats on LEV engines (except the LEV 80)

are being widened to help increase valve and seat durability.

The width is being nearly doubled from .040 (1 mm) to

.078 (2 mm). This can be done on the LEV engine because

of the unique design of the valve seats and cylinder block.

This design helps remove heat from the valve seat area

by distributing it into the cylinder block and then dissipating

it in its flow through design. This is also being done in

conjunction with the use of heavier valve springs. The

combination of the two may also help eliminate the light

to no load popping that sometimes occurs when engines

are running at low speeds.

CLIMATE GUARD™ OHH

Although it was introduced last year, it now has a title,

“Climate Guard™”. The official name for the air filter

system used on emissions engines that are run in both

warm and cold weather environments. This system has

a baffle, that when placed in the winter position blocks

cold air from the blower housing. Warmer air is then

drawn through the air filter backing plate, this warmer

air prevents the possible icing of the breather tube inlet

to the carburetor. The icing is caused by crankcase

vapor/condensation from the breather system required

on emissions engines. When placed in the summer

position it allows the cooling air from the blower housing

to function normally, maximizing air filter life through

our Kleen Aire® system.

EMISSIONS INTEGRITY

Just a reminder to you and your customer that it is

required to maintain EPA and CARB compliance to use

“as built” factory original or approved parts. This means

parts used in, fuel metering systems, air induction

systems, ignition systems, exhaust systems and

crankcase breather systems must be Genuine Original

Tecumseh factory parts or their equivalent. Ask your

distributor about the Real Ones Parts program to prevent

any possibility of violating compliance regulations by

using less than OEM quality after market parts.

FUEL CAP TETHER

The fuel cap tether has made a come back in recent

years especially on recreational vehicles. This cap tether

may come in handy for the customer that has lost their

fuel cap while mowing or forgot to put it on. The part

number is 35480 and can be retrofitted to most newer

style fuel caps with the standard 1.750 (44.45 mm)

opening.

EMISSIONS SERVICE BULLETINS

A new series of bulletins have been earmarked to deal

specifically with emissions related concerns. These

bulletins will be designated by the “500” series

classification. The headings listed on these bulletins

will include, Date Issued; Engine Model Concerned,

Family; and D.O.M. (Date Of Manufacture) affected.

The body of the bulletin will contain information

concerning; Potential Emission Control System Problem;

Affected Specifications Numbers; and Warranty

Inspection and Repair Procedure.

BULLETIN 501

Some LEV 115 engines built between date codes 8091

through 8166 have the incorrect bowl nut in the

carburetor. The suspect units will have the bowl nut on

the carburetor stamped with the number 174. This jet

should be replaced with part number 640087 which

will have the number 169 stamped on it. There are 30

different specifications involved. Check the bulletin to

determine if any units you may work on qualify.

BULLETIN 502

The following three model and spec numbers H35-

45690Z, H35-45726Z, and H40-55701A with D.O.M s

of 8079 through 8201 have been built with the incorrect

carburetor. You will need to locate and identify the

manufacturing number on the carburetor mounting

flange. If the number on the flange is stamped with the

number 5161 the unit has already been changed and

no repair is necessary. If the number is 5015 you need

to replace it by ordering part number 640172. This

carburetor will have the manufacturing number 5161

stamped on the flange.

HEAD GASKETS ARE BACK WITH SHORT

BLOCKS

Back in 1994 we removed the head gaskets from short

blocks. This was done because of thickness differences

between the gaskets used on older engines versus newer

product. The decision has been made to standardize

on the thicker gaskets on most short blocks. This will

have very little effect on engine power and will make

the short block procedure much simpler. The exceptions

will be the medium frame (HM and TVM) 8 and 10 hp

engines which will include both gaskets and allow you

to select dependent on its original gasket. This will be

a running change as inventories are upgraded.

MODEL NUMBER STANDARDIZATION

An effort is being made to standardize on the model

number designations used on lightweight vertical shaft

engines. In the past this designation has bounced back

and forth from horse power to cubic inch displacement.

Three more models have been brought into the cubic

inch displacement group. The VLV and OVRM series

engines are adding a VLV 126 (12.6 C.I./206.5cc) an

OVRM 105 (10.5 C.I./172cc) and a OVRM120 (12 C.I./

196.7cc). Previous designations used in these Models

will not be affected.

TC SERIES CARBURETOR SPACER BLOCK

We repeatedly receive calls from technicians regarding

TC series engines not starting after servicing of the

carburetor. During these evaluations we usually find

one of two things have occurred. The first is an incorrectly

installed insulator block causing the vacuum passage

to not be aligned with the carburetor. The correct position

is to have the impulse hole located in the spacer block

facing toward the spark plug end. The transfer passage

in the spacer block has to face toward the cylinder.

The second is sealant or adhesive blocking the passage

from previous improper service. Always check that these

passages are open and use new gaskets during service,

no sealant or adhesive is needed.

PROPER TRANSAXLE WARRANTY

INFORMATION BULLETIN 124

We have been evaluating transaxle warranty claims

which we have returned to service dealers for lack of

proper information. This evaluation has shown some

improvements could be made to our identification tag.

We have published and sent all manual holders Bulletin

124 explaining how to locate and read this information.

This information reviews both older models and the

improvements made to newer I.D. Tags. Tecumseh

wants to reimburse our dealers promptly, however, we

cannot without proper filing of the ESA-157R Claim form.

Please supply the needed information when sending

in claims.

Beginning this March of 1999 Tecumseh is implementing

a pilot warranty return program through selected CWD’s.

This new procedure will return warranty claims not

containing the needed information through your

distributor rather than directly to you. Your distributor

will work with you to obtain the needed information and

answer any questions, then re-submit the claim signed

by the distributor representative for prompt payment.

PROPER SHIFT COLLAR INSTALLATION

We regularly receive calls from technicians regarding

proper installation of the shifting key collar on transaxles.

The following tips should help you during servicing:

Shift collars will generally have one of several variations.

If the collar has an offset on one side, the thicker side

must face in toward the tips of the shift keys. If the

collar has no offset, check to see if there is a recess

on the inside diameter. If there is, the recess must

face toward the inside. A combination of offset and

recess always has both facing in.

VST DIAGNOSTIC PROCEDURE

The information on the following pages has been provided to help understand the internal operation of the

VST. Do not use this information to attempt any internal repairs. Tecumseh's current policy on hydrostatic

transaxles that have internal failures is to replace the complete unit. This has not changed. However, Tecumseh

would like to provide a failure checklist to assist in making an accurate evaluation of the complete tractor to

eliminate any unnecessary replacements. Here is a list of items to check and corrective actions to take.

To properly test the unit for power loss.

1. Allow the unit to cool before trying the following steps.

2. Put the shift lever in a position that is 1/2 of the travel distance from neutral to forward.

3. Place the tractor on a 17 degree grade.

4. Drive the tractor up the grade (without the mower deck engaged). The loss of power experienced

should be approximately 20%. This is considered normal. If the loss of power is approximately 50%,

this would be considered excessive.

5. Bring the unit to neutral, shift into forward and note the response. Care should be taken to move the

lever slowly to avoid an abrupt wheel lift.

To determine if the problem is with the hydro unit, all external problem possibilities must be eliminated. Here

are some potential problem areas.

1. Overheating: Heat can cause a breakdown in the viscosity of the oil which reduces the pressure

used to move the motor. Remove any grass, debris, or dirt buildup on the transaxle cover and / or

between the cooling fins and fan. Buildup of material will reduce the cooling efficiency.

2. Belt slippage: A belt that is worn, stretched, or the wrong belt (too large or wide) can cause belt

slippage. This condition may have the same loss of power symptom as overheating. Typically, the

unit which has a slipping belt will exhibit a pulsating type motion of the mower. This can be verified

visually by watching the belt and pulley relationship. If the belt is slipping, the belt will chatter or jump

on the pulley. If the belt is good, a smooth rotation will be seen. Replace the belt and inspect the

pulley for damage.

3. Leakage: The VST and 1800 Series have two oil reservoirs which can be checked for diagnostic

purposes. The first is the pump and motor expansion bellows, With a small diameter blunt or round

nose probe, check the bellows depth through the center vent hole. Proper depth from the edge of

that hole is 3-1/4 - 3-1/2 inches (8.25 - 8.9 cm).

The second chamber is for the output gears including the differential. FIRST make sure the tractor is

level, then remove the drain/fill plug. NOTE: Some units that do not have differential disconnect will

have two plugs. We recommend using only the primary plug. With a small pocket rule insert until you

touch bottom of case. You can then remove it and check for 1/4 - 3/8 inches (6.5 - 9.5 mm) contact

this is full at its 8 oz. capacity.

4. Low ground speed: If the linkage is not synchronized to absolute neutral, or the shift lever is not

properly fastened to the tapered control shaft, full forward travel may not be achieved. This may

cause a false reading and be misdiagnosed as a low power condition. This also could be caused by

the brake not releasing.

To determine absolute neutral, the hole in the tapered control shaft must face straight up and down,

at this point make sure the OEM linkage is in neutral. To properly fasten the control lever to the shaft,

torque the nut to 25-35 ft. lbs. (34 - 48.3 NM) of torque with the shaft and the lever in neutral.

When attaching the shifter arm to the shaft you must prevent any rotation during torquing. This can

be done by placing a long 5/16 bolt in the hole as shown in Illustration. Hold the bolt until the tapers

are locked and the nut torque is correct.

To make sure that the brake is not binding, drive the unit up a slight grade. Position the speed control

lever into neutral. The unit should coast backwards. If the unit does not coast back slowly, the brake

is not released from the brake disk. Adjust the brake linkage to release the brake completely when

the foot pedal is released.

5. Hard to shift: Typically hard to shift symptoms are not caused by the hydrostatic unit. The shift arm

should move with relative ease. Approximately 40-50 inch lbs. (4.48 - 5.6 NM) at the transaxle for

foot pedal units or 150-200 inch lbs. (16.8 - 22.4 NM) for hand operated units. This varies depending

on the type of linkage. Binding may occur in the linkage connections due to rust or moisture. Lubricating

these connections and checking for bent or damaged parts should resolve hard shifting.

VLV WELCH PLUGS

We have received comments from technicians regarding

VLV series engines hunting/surging, running erratic or

popping at low speed. The evaluation of these units has

revealed some poor sealing idle mixing chamber welch

plugs. After first checking the fuel condition, air filter

and spark plug, the engine still exhibits one of these

conditions. We suggest that while the engine is running

you spray the welch plug area with spray carburetor

cleaner. If the run quality changes it would indicate a

leak around the welch plug requiring repair. Completely

clean the welch plug area, then re-seal the plug using

fingernail polish which should eliminate the problem. If

the run condition does not change when you spray the

welch plug area, further inspection will be needed.

LEV ENGINES MIS-FIRING FIXED LINE

TRIMMERS

We have been evaluating field comments regarding

LEV engines popping or mis-firing out of the muffler.

These particular models of LEV are used on the new

fixed line trimmer applications equipped with a remote

throttle stop in the control. We have found some production

models where the ignition ground tab on the throttle

control plate was positioned very close to the blower

housing causing intermittent grounding. Should you

encounter this condition remove the extra blade from

the wire terminal as shown. This is done using a side

cutter to trim the extra blade away. This procedure

may require the removing of the blower housing to access

the speed control.

HH AND OH CAST IRON CRANKSHAFT AND

CAM GEARS

In an effort to keep parts available for the OH and HH

cast iron series engines, we have decided to obsolete

the straight cut gears and will make available only

crankshafts with helical cut gears. When using this

crankshaft to repair older cast-iron units equipped with

straight cut crankshaft, camshafts and governor gears,

it will be necessary to order new helical cut camshaft

and governor gears to match tha crankshaft. When

repairing the OH Cast Iron series engine you will need

a 34751 helical governor gear and 34752 helical

camshaft gear. If you are repairing a HH Series engine,

order 34691 helical governor gear and 34692 helical

camshaft gear.

TC AIR GAP REMINDER

We occasionally hear complaints of poor or hard starting

TC engines used on post hole diggers, ice augers and

cultivator tillers. In addition to the normal checks for

fresh fuel, good spark plug and a clean filter, check the

CDI ignition module air gap. The TC series uses two

different settings dependent on application and model

which effect proper ignition timing. All TC200 and 300

rotary mowers applications use a .0125 gap (.317 mm),

gap tool 670297. All other TC300 models use a gap of

.030 (.762 mm), gap tool 670321.

Miscellaneous Product News

SNOW PRODUCTS STARTS

There are times when dealers are confronted with

customers who purchase snow equipment when the

ambient temperature is above 50° F (10°C) The starting

procedures at these temperatures should not require

priming the engine. Therefore we have included the

number of primes needed to start the engine at different

temperature ranges in the operators manual. This will

possibly prevent the over priming and flooding of engines

at warmer temperatures, and eliminate this situation.

The guidelines are as follows. With the choke on and

temperatures below 15° F (-9°C) three primes, 15° F

(-9°C) to 50° F (10°C) one prime, and above 50° F

(10°C) zero primes choke only.

NEW SMART START PACKAGING

This product has been extremely popular in its inaugural

year and has established itself firmly in the market place.

This was done primarily through the counter display

part number 730255. This fuel stabilizer is now available

in a three packet bubble pack display part number

740063. This product has made fuel stabilization so

easy that many consumers and shop owners use it

year round, not just for off season storage. Just one

packet stabilizes up to 21/2 gallons (10 Litres) of fresh

fuel. This dry type stabilizer dissolves rapidly and does

not create a mess or stain like many liquid varieties and

requires no complicated mixing formulas.

VST REPLACEMENT PROGRAM

BULLETIN 307

We have again reviewed the issue of possible field

service of the VST series transaxle. We have decided

that Bulletin 307 must stay in effect for an indefinite

period of time in the United States only. We would like

to review some of the key issues that are driving this

decision. The VST series transaxles used in this program

are manufactured using the following stringent program:

1. Initial review of your warranty claim filed with the

unit describing the condition.

2. Complete disassembly, cleaning and inspection of

all components.

3. Replacement of any parts not meeting original

manufacturing specifications.

4. Reassembly in a clean room environment (dust and

dirt free) to original new specifications. Re-filling the

pump and motor side with a special synthetic oil used

in the aviation industry. All air is the removed through

a bleeding off process.

5. After re-assembly the unit is pressure tested insuring

unit integrity.

6. We then load test the unit checking axle output torque

and speed on a special test machine to assure the

customer of trouble-free operation. This test bench

alone would cost a service center $20,000 US dollars

to duplicate, adding to the complexity of field service.

MICROFICHE UPDATES

During the past several months we have increased the

number of Microfiche cards per mailing in an effort to

keep your data as current as possible. During 1998

you should have received the following card numbers

1, 3A, 3B, 8A, 8F, 9B, 10C, 12A-1, 12B, 16B, 16C, 18B,

18B-1,18B-2, 24, 24A, 27A, 30, 31, 33, 35, 35A and

REVISED SOFT PULL STARTER

From production starting September 1998, a revised

soft pull starter will be used. Although the design is

very similar to existing product, improvements have

been made to the housing, the pulley material, design,

and the pawls. These improvements have been aimed

at improving the durability of the unit, and to improve

the way in which the rope is held on the pulley. Individual

spare parts for this starter will be made available, and

the repair procedures are identical to the existing product

which uses the roll pin to secure the pulley to the housing.

STARTER REPAIR KIT

Utilizing the parts used in the new soft pull starter, a

repair kit will be made available to service existing soft

pull starters. This kit, which is available under part

number 16630041, will consist of pulley, recoil spring

and retainer, pawls, pawl springs and retainer, together

with new roll pin assembly.

VALVE CLEARANCE CHECK

ELECTRIC START ENGINES

Electric start engines are now equipped with a flywheel

that features a plastic ring gear in place of the aluminum

ring gear that was cast as part of the flywheel. This is

more robust than the original but also provides much

quieter operation. It is however essential that the

clearance between the flywheel ring gear and the starter

pinion is set correctly. There should be a clearance of

1/16” (1.6 mm) between the tip of one tooth and the

root of another. This can easily be checked using a

sized piece of wire. It is essential to check this clearance

when replacing a flywheel that has broken teeth, as it

is possible that when the failure occurred, the starter

mounting has become distorted, increasing the

clearance. Failure to check this clearance will result

in premature ring gear failure.

INLET VALVE OIL SEAL

Most premium engines are now equipped with an inlet

valve oil seal which acts as a top valve spring retainer.

This seal, which is part number 19610001, should be

replaced whenever it has been removed from the valve

stem. The correct installation is shown on the adjacent

drawing.

FLYWHEEL ATTACHMENT MV100S ENGINES

Some MV100S engines utilize an adapter collar to locate

them to the crankshaft as opposed to the standard

flywheel key. The engine specification number will

identify which system is used. When reinstalling the

flywheel that utilizes this collar, it is necessary to press

the collar into the flywheel taper flush to the inside hub

before installing the flywheel to the crankshaft. The pressed

ridge in the collar will align with the flywheel keyway.

3 AMP CHARGING SYSTEM

Some Futura 60 engines are now equipped with a 3 amp

DC charging system to enable the use of an electric

clutch. Should the charging be in doubt, it should be

checked in the following way.

1. Start the engine and let it run at high speed.

2. Disconnect the engine from the machine’s wiring

loom by disconnecting the black multi connector.

3. Set the engine speed to 3000 rpm.

4. Check the DC voltage output by connecting a

voltmeter between the red wire on the 4-way

connector to earth. Minimum reading should be 9.5

volt DC. At this minimum reading the system is

working correctly.

5: If this minimum reading is not achieved check the

AC voltage output by pulling back the sheathing

covering the diode and connecting the voltmeter (set

on AC scale) between ground and output wire prior

to the diode. The reading should be 22 volts AC at

3000 rpm. If this minimum reading is achieved the

diode at fault must be replace.

6. If this minimum reading is not achieved than the

alternator coils are at fault and require replacement.

7. Do not forget to reconnect the connector to the

machine wiring harnes when repair has been

completed. (If the machine still exhibits electrical

problems and the charging system checks out OK,

then the machine should be checked for a poor battery,

poor connections, failed relays etc).

ENGINE IDENTIFICATION

Starting September 1997 all Tecumseh Europa engines

were identified by an adhesive label affixed to the blower

housing. The actual positioning of this label varies

according to engine model. On vertical shaft engines

it can usually be found on the oil filler side towards the

spark plug. On horizontal shaft engines it can usually

be found adjacent to the spark plug. A sample of this

label is shown opposite. These labels are in addition to

the existing information stamped on the crankcase.

CATALYTIC CONVERTERS

Many of our engines can now be specified with catalytic

converter which takes the form of a tablet or wire mesh

which is installed within the muffler. These mufflers

can be identified by the word “KAT” pressed into them.

As with automotive catalytic converters, it is necessary

to follow certain ruler if the catalytic converter is to remain

effective for a reasonable period. Obviously the customer

must be advised only to use unleaded fuel. In addition

they should be made aware that the engine should not

be over-filled with oil, or tipped in a way to allow oil to

flood into the combustion chamber (spark plug down).

Catalytic equipped engines are only supplied with primer

carburetors, but the customer should also be made aware

of the danger of unnecessary over-priming of the engine.

With a little care the catalytic converters will be effective

for many seasons.

CONNECTING ROD

The connecting rod used in our European manufactured

engines ranging from 3.7 - 5.5 HP has been modified

in the following areas.

1. Added oil feed channel to the beam of the connecting

rod.

2. Added chamfer to the connecting rod/cap parting

line.

3. Added oil groove to connecting rod cap.

This is a running change to service part numbers

16110010 and 16110011 and will occur as inventories

change.

ISSUED: May 1971

REVISED: October 1998

SUBJECT: Gasoline and Engine Oil Recommendations for 2 and 4-Cycle Engines

GASOLINE

Tecumseh Products Company strongly recommends the use of fresh, clean, unleaded regular

gasoline in all Tecumseh engines. Unleaded gasoline burns cleaner, extends engine life, and

promotes good starting by reducing the build-up of combustion chamber deposits. Leaded gasoline,

gasohol containing no more than 10% ethanol, premium gasoline, or unleaded gasoline containing

no more than 15% MTBE (Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or

10% ethanol, can be used if unleaded regular gasoline is not available.

Reformulated gasoline that is now required in several areas of the United States is also acceptable.

NEVER USE gasoline, fuel conditioners, additives or stabilzers containing methanol, gasohol containing

more than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl

Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives,

or white gas because engine/fuel system damage could result.

See STORAGE instructions in Technicians Manual, Operators Manual, or Bulletin 111.

For year round fuel stability in and out of season, use "Smart Start" part number 730245.

FUEL ADDITIVES

Only fuel additives such as Tecumseh's fuel stabilizer Smart Start part number 730245 or

liquid varieties can be used when mixed properly. For winter applications, Isopropyl alcohol

fuel dryers may be used in the fuel system but must be mixed at the proper ratio recommended by

the manufacturer. NEVER USE METHANOL BASED DRYERS.

OILS

2-CYCLE

Tecumseh two cycle engines require the use of a NMMA TC-W3 or TC-WII certified oil.

TECUMSEH RECOMMENDS USING TWO CYCLE OIL PART #730227, which is a premium blend

that ensures cylinder wall lubrication, mixes easy, does not separate and is specially formulated

for use in air or water cooled two cycle engines.

The proper fuel mixture ratio of oil to gasoline for specific engines will be found in the owners

operating instructions and on the decal attached to the blower housing or fuel tank of the engine.

FOR NEW ENGINES: USE TWICE THE NORMAL OIL QUANTITY FOR THE FIRST GALLON OF

FUEL ACCEPT ON TC SERIES WHERE THE STANDARD MIX RATIO IS SUFFICIENT.

4-CYCLE

TECUMSEH FOUR CYCLE ENGINES REQUIRE THE USE OF A CLEAN, HIGH QUALITY DETERGENT

OIL. Be sure original container is marked: A.P.I. service SF thru "SJ" or CD.

TECUMSEH RECOMMENDS USING ONE OF THE FOLLOWING FOUR CYCLE OILS THAT ARE

SPECIALLY FORMULATED TO TECUMSEH SPECIFICATIONS.

DO NOT USE SAE10W40 OIL.

FOR SUMMER (Above 320F) USE SAE30 OIL. PART #730225

(SAE10W30 is an acceptable substitute.)

Use SAE30 oil in high temperature, high load applications. Using multigrade oil may increase oil

consumption.

FOR WINTER (Below 320F) USE SAE5W30 OIL. PART #730226

(SAE10W is an acceptable substitute.)

(BELOW 00F ONLY): SAE0W30 is an acceptable substitute.

NOTE: For severe, prolonged winter operation of HH120 model, SAE10W oil is recommended.

Subject: RECOIL STARTER WILL NOT ENGAGE WHEN PULLED

Models Effected:Small Frame (3 thru 6 HP) Horizontal and

Vertical Engines with DOM 7335 thru 8150

If you have experienced an occasion where the recoil starter will not engage when the rope is pulled,

a simple repair may solve the problem. This repair will only affect starters that have the white plastic

locking tab located in the top/center of the starter. The locking tab may be covered by a round

protective decal or could be located in the recoil under a decorative cover. The decorative cover will

have to be removed to allow for repair. However, it is not necessary to remove the recoil starter from

the engine to make the repair.

To make the repair you need to remove the protective decal to expose the white plastic locking tab.

Use a small flatblade screwdriver or needlenose pliers to pry up on the tab and remove it from the

starter. Discard the old tab and replace it with a new metal locking tab part #590760, which also

includes a new protective decal. Press the new metal locking tab down into the retainer until it snaps

into place. Place the new protective decal over the tab hole to prevent any water or debris from

entering the starter.

This procedure and paperwork should take approximately 15 minutes to complete. An ESA 157R

warranty claim form should be filed through normal channels.

SUBJECT: Peerless® Model VST 205 WARRANTY Replacement Program

The Service and Engineering groups of Tecumseh have reviewed extensively the servicing of the VST

205 Hydrostatic Transaxle. After review of the complex issues of servicing this unit, we have decided

on a unique approach for Tecumseh to handle IN WARRANTY servicing by complete replacement, if

needed, with factory furnished units. These units may be Tecumseh re-manufactured units or new

units at our discretion.

Effective November 15, 1997, the following procedure is to be followed by all Authorized Tecumseh

Service Centers if an Internal Failure occurs WITHIN THE WARRANTY PERIOD. We are enclosing the

revised Warranty Policy reflecting this change.

1. Be sure you have reviewed the trouble shooting section of the Peerless® Technicians Handbook,

No. 691218, to insure the problem is internal and not a linkage problem. All external components

serviceable previously such as pulley, brakes, and levers are still serviceable as before.

2. If you have identified the trouble as internal, contact your distributor for replacement authorization

under the normal warranty authorization procedure.

3. You will then need to look up the replacement transaxle using the attached list of replacements or

the parts look up system you have chosen (i.e., microfiche, computer or paper). NOTE: Place an

"R" on the end of the service replacement part number when ordering from your normal source.

The unit will be shipped N/C with freight prepaid direct to your dealership. Example: Part #794667

(R). If your replacement model had an "A" suffix, change it to an "R" as referenced.

4. Ordering is done through your normal source of supply. DO NOT attempt to combine any "R"

number with a regular order. Only the "R" will be shipped N/C Prepaid. Any added orders will be

kicked out (not shipped).

5. You then file your DISTRIBUTOR AUTHORIZED, COMPLETELY FILLED OUT ESA157 warranty

claim with us for the R&R of the transaxle. Upon receipt of the warranty claim in Grafton, Wisconsin,

Tecumseh will issue a recall tag through UPS to pick up the unit for return to us.

6. When your claim is matched up with your returned transaxle, we will process it for prompt payment.

7. Before returning the defective transaxle, place a COPY of the ESA157 warranty claim in the original

box, which should be used for return shipment of the transaxle.

8. This program will be in effect for the United States only.

We appreciate your assistance in this warranty replacement procedure.

 Locate the access plug under the cooling fan. This plug and surrounding area must be cleaned to

prevent contamination of internal parts during this procedure. Before removing the plug, pack a cloth

in the housing pocket to absorb excess oil.

 Clean the bellows cover plate.

 Place a piece of masking tape over the hole located in the center of cover plate. This will prevent air from

entering the bellows area when access plug is removed, and prevent oil from coming out access hole

when plug is removed.

 Using a needle nose pliers, remove the access plug described above. When the plug is removed, a small,

quantity of oil will flow out of the transaxle. This is normal and will not effect its function.

 Insert a #30 torx or 5/32 allen wrench into the access hole and locate the adjustment screw. Adjust

the screw clockwise 1/4 turn at a time to increase motion control effort.

NOTE: If for any reason the effort to move the motion control lever becomes too excessive, reverse the above

procedure by turning the adjustment screw counterclockwise 1/4 turn.

 Clean the access plug and insert it into position using the torx or allen wrench.

 Clean spilled oil from transaxle and reinstall battery box and battery into tractor. When connecting

battery be sure to connect the RED battery cable first.

 An effort of 150-200 in-lbs. of torque to move the transaxle motion control lever is required for hand

control units and an effort of 40-50 in-lbs. of torque to move the transaxle motion control lever on foot

MODELS AFFECTED: VLV 50 through 66

SERIAL NO'S AFFECTED: 7002 through 7128

We have received comments from the service system regarding instances of NEW VLV model

engines exhibiting smoke from the muffler during initial engine operation. These instances of

smoke from the muffler in a new engine may be caused by storage or shipment with the

spark plug pointing down.

BEFORE performing the procedure below please make sure the engine has been run for at

least 30 minutes to burn out any oil residue inside the muffler. If the smoking continues

after this time period proceed below.

After investigation we have determined the cause of the smoking. This is the result of an

irregular casting surface in the valve spring box, which does not allow proper seating of the

seal allowing oil to pass.

PROCEDURE:

1. Remove the muffler, cylinder head and valve box cover.

2. Remove the Intake valve spring, valve and seal.

3. Install the NEW valve stem seal part no. 40016A as shown (see illustration).

4. Replace the cylinder head gasket part no. 36061 and valve box cover gasket part no.

ENGINE I.D. BULLETIN 123

With the implementation of emissionized engines, we were required to change the engine identification

system we used. This new system has caused many warranty claims to be rejected for a lack of proper

information. We have published Bulletin 123 to help you understand the needed information. Please

make sure you supply the information so we can reimburse you promptly.

Beginning this March of 1999 Tecumseh is implementing a pilot warranty return program through selected

CWD’s. This new procedure will return warranty claims not containing the needed information through

your distributor rather than directly to you. Your distributor will work with you to obtain the needed

information and answer any questions, then re-submit the claim signed by the distributor representative

for prompt payment.

BOX 5 ENGINE/TRANSMISSION INFORMATION:

Enter the entire model, specification, serial (DOM) number of the engine/transmission being

repaired. When a repair is performed to a short block, enter the short block model and serial

number. Check the appropriate box to indicate if the equipment was received mounted or

detached from the OEM's equipment.

TECUMSEH 4-CYCLE LUBRICATION REQUIREMENTS

We often receive questions from both customers and dealers regarding the type and brand of oil we

recommend.

Tecumseh recommends the use of a high quality, brand name petroleum based oil in our engines.

Very few air cooled engines have any type of oil filtration system, making regular oil changes critical

to remove impurities from the engine and maximize engine life. Consult the operators or repair

manual for the oil change interval and viscosity based on equipment operating temperature.

OIL may be used in a variety of

2 cycle engines including:

outboards, lawnmowers, snow-

up to 50:1.

PREMIUM BLEND FOR BOTH AIR AND WATER

COOLED ENGINES ENSURES CYLINDER

WALL LUBRICATION

We also receive calls regarding what type or brand of two cycle oil to use in mini tillers and snow products.

The proper type and ratio of two cycle oil is critical to long life and low maintenance of the engine. Tecumseh

tests engines using NMMA (National Marine Manufacturers Association) certified oil such as Tecumseh part

number 730227, but any NMMA certified two cycle oil will provide adequate lubrication for long life. The use

of non certified oils and improper mix ratios can cause severe engine problems and possibly void warranty

consideration if the damage was the result of poor lubrication.

Our position regarding two cycle lubrication is simple, use only NMMA certified oil or Tecumseh two cycle oil

mixed at our recommended ratio and your engine will be properly lubricated. Please do not recommend using

anything else to your customer, this will avoid getting you caught in the middle, should problems occur.

TECUMSEH 2-CYCLE ENGINES REQUIRE THE USE OF BIA, NMMA, TC-WII OR TC-W3 CERTIFIED

OIL, NON-BIODEGRADABLE.

NOTE: DOUBLE THE OIL QUANTITY FOR FIRST GALLON OF FUEL/OIL MIXTURE TO ASSIST BREAK-

NOTE: FOR TC AND CRAFTSMAN ENGINES, DOUBLING OF THE MIX IS NOT REQUIRED.

Tecumseh's Education Department welcomes the challenges facing our industry from emission controls to market

changes. We believe that education is a vital part of meeting these challenges. This season, we will again be

using the Parts Smart and Plus One computer parts look up system's as an interactive part of the class.

Friday mornings at the Douglas facility or Friday afternoons at the Grafton facility, will be reserved for the Master

Technician Testing at no additional charge.

THE TESTING WILL BE AVAILABLE ONLY IF PRE REGISTERED

ON THIS APPLICATION. NOTE: YOU MUST HAVE PASSED THE ESA / OPE TECHNICIAN 4 CYCLE TEST

AS A PREREQUISITE. You can only be scheduled for the test by submitting proof of holding this

certification.

Both Course I and Advance Course utilize engine and transmission product for teardown and re-assembly

extensively. The following are highlights and available school dates for your consideration.

We look forward to seeing you in Grafton, Wisconsin or our Douglas, Georgia school.

If you have any further questions, please call us.

COURSE I

Updating you on Tecumseh engines is

complemented with a current mixture of our

transmissions and transaxles.

Education is an ongoing process to ensure you

and your customers of the best possible service

repair.

Course I is not a “basic” course. It is designed to

assist new technicians and those crafty veterans

with current repair procedures.

Advance Course is available only after you have

completed a Course I School.
