Yancheng Tractor Factory
The Yancheng Tractor Factor is located, as you may guess, in the city of Yancheng, Jiangsu
province, China, and is about 100 miles north of Shanghai.
Yancheng is one of thirteen municipalities of Jiangsu province.
Yancheng is situated by the Yellow sea. With the coastal
marshland covering an area of 453,000 ha with rich resources,
Yancheng is an important production center for clams, prawns
and eels. The two natural protection regions of red-crowned
cranes and David' s dear have been set up in Yancheng. The
development of agricultural economy of the city is in full swing, making the city
a new commodity grain and cotton base in China. The local industrial structure
has been completed in Yancheng with industries like textiles, machinery,
electronics, chemical, pharmaceutical, food processing and construction materials
industries as its backbone. The arts and crafts, native and special products of the
city are of unique styles.
The tractor factory
was originally built
about 50 years ago. As
you can see from figure
3, this factory was a
less than ideal
environment in which
to build. As of the
spring of 2002 all
tractors were being built in a new factory.
Average wage per person in Jiansu Prov for 2003 was 9200 Yaun (Cdn $1400).

Preventing Farm Machine Hazards
AEX-593-91
Thomas L. Bean
Each year, 2,600 farm residents are killed and 230,000 disabled in farm-related injuries, many due to
farm machinery. Farm machinery uses mechanical power to do work. This creates a number of possible
hazards for both operators and bystanders. Even though manufacturers take many steps to make
machinery safe, all hazards cannot be removed. Some machine parts cannot be completely shielded and
still do their job. For instance, a totally enclosed cutting blade could not cut.
Many machinery-related accidents result from human error. The operator either forgot something, took
a shortcut or a risk, ignored a warning, wasn't paying close attention, or failed to follow safety rules. In
addition, guards removed for maintenance often aren't replaced.
There are many different kinds of farm machinery: mowers, tractors, shredders, harvesters, grinders,
blowers, augers, balers, etc. They all have similar characteristics and hazards. You can be cut, crushed,
pulled in or struck by an object thrown by these machines. They have cutting edges, gears, chains,
revolving shafts, rotating blades, pinch points and other hazards. You can also be injured if you fall
while working on or near any of these machines.
Accidents with farm machinery are often serious, even fatal. It is important to recognize and be alert for
machine hazards and to take precautions to avoid injury.
Shear and Cutting Points
Shear points (Fig. 1) are created when the edges of two objects are moved
together closely enough to cut a soft material, as with a pair of shears or an
auger. Cutting points are created when a single object moves forcefully or
rapidly enough to cut, as with a rotary mower blade.
Both shear and cutting points are created on machinery designed to cut, such as
harvesters, and on those that are not designed to cut, such as augers. They are hazardous because of
their cutting force and they often move so rapidly that they may not be visible, so it is easy to forget
they are operating or to underestimate the hazard.
Because some shear and cutting points cannot be guarded, it is important to be aware of their hazard
and stay alert when they are operating. It is also important to warn others and to look out for their
safety. This is especially true if there is a danger of thrown objects while using cutting-type equipment.
Version 0.2 Page 11 of 52
Figure 7. Shear Point
Jinma 200 series Tractor Users Manual
MCE 2004.01
Pinch Points
Pinch points are another hazard of farm machinery (Fig. 2). Pinch points
(which should be more appropriately named mangled or maimed points) are
formed when two rotating objects move together and at least one of them
moves in a circle. For example, the point at which a belt runs into a pulley is
a pinch point. Belt drives, chain drives, and gear drives are other sources of
pinch points in power transmission devices. Feed rolls, gathering chains and
similar equipment designed to draw crops into the machine also create pinch
points.
Fingers, hands and feet can be caught directly in pinch points, or they may be drawn into the pinch
points by the inertia of the moving part or loose clothing that becomes entangled. Contact may be made
by falling or brushing against unshielded parts. You can become entangled in pinch points if you take
chances and reach or work near rotating parts. Machines move too fast to get out of a pinch point once
you become caught.
To avoid injury from pinch points, be aware where pinch points occur and avoid them. Wear clothing
that fits well and is not loose or floppy. Never reach over or work near rotating parts. Turn off
machinery to work on it. Always replace shields removed for maintenance.
Wrap Points
Rotating shafts are the most common source of wrap-point accidents, although any exposed machine
part that rotates can be a wrap point. A cuff, sleeve, pant leg, long hair or just a thread can catch a
rotating part and result in serious injury. Entanglement with a wrap point can pull you into the machine,
or clothing may become so tightly wrapped that you are crushed or suffocated. In other cases, you
could be thrown off balance and fall into other machinery parts.
Even a perfectly round shaft can be hazardous if there is enough pressure to hold clothing against the
shaft. Hazards increase with shafts that are not round. Clothing is more likely to catch if there is dried
mud or manure on the shaft, or if the shaft is nicked. Ends of shafts that protrude beyond bearings are
also dangerous. Universal joints, keys and fastening devices can also snag clothing.
Check all equipment for potential wrap points and, if possible, shield those that can be shielded.
Replace any damaged manufacturer-installed warning labels and place warnings on equipment parts not
previously labeled. In addition, consider painting them a bright color, perhaps with wide stripes. Be
aware of wrap points and be alert to their danger.
Crush Points
Crush points are created when two objects move toward each other or one object moves toward a
stationary object. For example, hitching tractors to implements (Fig. 3) creates a potential crush point.
Hitch accidents most commonly occur to fingers placed at the hitching point. Wait until the tractor has
Version 0.2 Page 12 of 52
Figure 8. Pinch Points
Jinma 200 series Tractor Users Manual
MCE 2004.01
stopped before stepping into the hitching position. If possible,
arrange the hitch point so that the tractor can be backed into position
without anyone between. Always know what the other person is
doing.
Failure to safely block up equipment can result in a fatal crushing injury. A jack may slip, a hose or
overhead support may break, or the equipment may roll. Take extra precautions when working with
machinery that is raised for any reason. The operator's head or chest can be crushed between the
equipment and a low beam or other part of a farm building. These accidents usually occur when the
machine is being operated in reverse. Tree limbs are also potential hazards when working with tractors
and other machinery.
To prevent being crushed or pinned, recognize and avoid potentially dangerous situations. Block all
machinery securely if you must work under it. If an implement can roll freely, block its wheels so it
cannot roll.
Free-Wheeling Parts
Many machine parts continue to spin after the power is shut off, including cutter heads of forage
harvesters, hammer mills of feed grinders, rotary mower blades, fans and flywheels. Never touch these
parts until they have stopped moving. This could take 2 to 21/2 minutes.
Springs
Compressed springs (Fig. 4) will expand with great force when
released, and springs that are stretched will contract rapidly when
released. Know what direction a spring will move and how it might
affect another machine part when released, and stay out of its path.
Burn Points
Be aware of burn points: mufflers, manifolds and even gear cases under adverse climatic conditions.
They may not be severe enough to seriously maim, but they can startle the operator enough to cause
him or her to "jump" into more deadly danger.
Hydraulic Systems
Hydraulic systems contain fluid under extreme pressure. Before loosening, tightening, removing or
otherwise working with any fittings or parts, relieve this pressure. Jet streams from even pinhole leaks
can penetrate flesh. In addition, the liquid is often hot.

Figure 9. Crush Points
Jinma 200 series Tractor Users Manual
MCE 2004.01
Before attempting any service on hydraulic systems, shut off the engine that powers the hydraulic
pump. Lower the implement to the ground and relieve the pressure. Follow instructions in the
operator's manual because the specific procedures for servicing the systems are very important to your
safety.

Control and Operation of the Tractor
Starting Engine
Before starting the engine, check fuel, lubricating oil and coolant level. Put gear-shifting lever in neutral position.
Note: The ignition switch must be in the ON position for the alternator to charge the battery.
Warm weather over 32 Degrees F
1. Turn the starting switch clockwise to "start" position. The starter drives the engine. The starter must not be
operated more than 5-10 seconds for each start. Only after an interval of at least 2 minutes should the
engine be started again.
2. When the engine starts, release the key and it will return to the on position.
Cold weather below 32 Degrees F
Turn key clockwise to first position past "on" for approximately 20 seconds to
operate glow plugs. In this position, you will notice the amp gage will show
discharge. This will let you know that the glow plugs are operating. Then
proceed to start as in warm weather. In extreme cold conditions or if battery is
low, you may use the decompression lever to ease starting.
Operating the Tractor
After the engine is started, run it at moderate speed for 5-10 minutes to allow the engine to warm up. After the
water temperature reaches 70 degrees Celsius the tractor can be operated by the following steps:
1. Lift any attached implements.
2. Depress the clutch pedal, put the gear-shifting lever into the desired gear, and release the parking brake
lock pawl of the brake pedal.
3. Observe your environment - make sure there are no obstructions or persons are in the way.
4. Gradually release clutch pedal and the tractor will start off smoothly.
5. During operation make sure all readings on gauges are indicating in the normal range.
6. DO NOT RIDE THE CLUTCH. Remove your foot from the clutch pedal when tractor is in motion.
Failure to do this will cause premature clutch failure.

Driving the Tractor
1. When transiting between job sites or running on highway, lock the left and the right brake pedals together
with brake lock plate.
2. In field operation, one-side braking can be used to reduce turning radius. DO NOT use one-side
braking for sharp turning when the tractor is running at high speed or is being used for transportation on
highway. If one-sided braking is used in these conditions, overturning and/or damage to components is
possible.
Proper speed should be selected for best productivity.
Stopping the Tractor
•Throttle the engine down to lower the speed of the tractor.
•Depress the clutch pedal quickly and shift the gear-shifting lever to neutral position.
•Release the clutch pedal and let engine run at idle.
•Depress the brake pedals to stop the tractor, then lock the pedals with the parking brake locking pawl.
Note: In case the tractor has to be stopped suddenly, clutch pedals and brake pedals should be d
depressed simultaneously. DO NOT depress the brake pedals only. Depression of only brake
pedals will result in damage to the tractor.
•If the tractor is to be parked for quite a while, the engine should be stopped. After the engine has been
unloaded, it should run at low speed until the cooling water temperature drops to 70 degrees Celsius or
lower. Pull out fuel cut-off rod to bring the engine to a stop.
Note: Never stop the engine when its temperature is very high. Do not stop the engine with
decompression mechanism.
•Turn the key switch to "O" (off) and remove key. If the tractor is going to be stored, turn off the fuel tank
valve.
Tractor Operation Safety
The following safety regulations are very important for protecting operator and tractor from
hazards. They should must be strictly followed during operation.
•Carefully inspect the working condition of the engine and main components, and listen for any abnormal
sound or noise. Be sure to check the adjustments of the clutch and brake. Check and tighten any loose
nuts and bolts on main components of the tractor.
•Make sure there are no people or obstacles around the tractor before starting and operating tractor.
•Do not get on or off the tractor while it is running. NEVER check, adjust or repair any part of tractor or
attachment with the engine running.
Version 0.2 Page 22 of 52
Jinma 200 series Tractor Users Manual
MCE 2004.01
•Before going up or down a slope, proper speed should be selected. Do not coast, turn sharply or shift
gears while driving down a slope.
•During transiting between job sites, lock the brake pedals together. One-side braking should not be used
for sharp turning when the tractor is running at high speed or with a full load.
•If front end of the tractor rises up in operation, throttle down the engine, disengage the clutch and reduce
the load immediately to protect the tractor and operator from longitudinal overturning.
•If the engine runs away, immediately pull out the fuel cut-off rod, move decompression lever to
"decompressing" position or plug up fresh air into the engine instead of disengaging clutch.
Diesel runaway can be caused be fuel oil dilution of the engine lube oil. If the
engine runs away, find out why and repair the fault(s) before attempting to use the
machine.
•Lighting equipment must be serviceable during operating at night or on public roads.
•Transmission lever should be placed in the neutral position when the tractor is running idle.
•Passengers should never be allowed to ride on tractor or attachments.
•Never get under any implement or attachments while raised with hydraulic lift, with out first using safety
stands to support weight of attachment.
Control and Operation of PTO driven Devices
Control and Operation of PTO
PTO can be engaged and disengaged by using the PTO control lever on the right side of the transmission box.
Push clutch pedal all the way down when engaging or disengaging PTO. To engage PTO, push down the control
lever from the front and upper side for 1000 rpm and up for 740 rpm. To disengage, put the control lever in the
middle position. The operation steps are as follows:
•Unscrew the PTO safety shield and couple the desired driven machine to the PTO shaft.
•Put the gear-shifting lever at the neutral position.
•Depress the clutch pedal fully then shift the PTO control lever to the proper "engaged" position.
•Release the clutch pedal slowly and the driven machine will run. First let the driven machine run at slightly
open throttle to ensure that nothing is wrong with the driven machine. Then run with open throttle, and put
the driven machine into operation.
•Care should be taken when operating the PTO. On some attachments, the drive shaft may hit or come in
contact with tractor or attachment when in the raised position.
Note: When the tractor implement travels for a long distance, the control lever should be shifted
to the neutral position to cut off the power so as to avoid damaging the implement and causing
physical damage.

Jinma 200 series Tractor Users Manual
MCE 2004.01
Control and Operation of Hydraulic Hitch System
The hydraulic hitch system serves to attach, lift and lower implement, as well as adjust and maintain the working
position of the implement in order to meet different requirements of various implements and operations. To raise
and lower the implement, simply move the control lever of the distributor.
Depending on the type of work to be done, type of implement used and/or field conditions, the hydraulic hitch
system provides various functions to obtain satisfactory work quality.
Position Control
The position of the implement can be adjusted by moving the control lever of the distributor. When
the desired position of the implement has been obtained set the position of the stopper on the return
rod to limit the control lever. Tighten the stopper on the rod with the screw, so that the lever can be
pushed to the same position every time. Adjustments may be made for different implements.
Floating Control
Floating control is suitable for field plowing. In floating control, the supporting wheel is
needed for implement. During plowing, hold the control lever of distributor at "lowering"
position (i.e. push the control lever of distributor forward with the return stopper. Do not
return the control lever to the neutral position). The hydraulic circuit is then in "floating"
control. Using floating control, the plowing depth is controlled by the change in height of the
supporting wheel. The uniform plowing depth will be obtained in the field with changes of soil
resistance.
Control of the Lowering Speed of the Implement
Turn the lowering speed adjusting valve to control the lowering speed of the implement. The
lowering speed should be selected properly according to the weight of the implement and
hardness of soil surface in order to prevent the implement from being seriously impacted and
damaged. To reduce the lowering speed, turn the lowering speed adjusting valve clockwise.
To increase the lowering speed, turn the valve counterclockwise.
Operation of Hitch System
Adjust the implement according to the Implement Operation Manual before attaching the implements to
the hitch system of the tractor. In plowing, adjust longitudinal and lateral level of plow in order to get the
implement square to the ground.
Adjusting of Longitudinal Level
Adjust the length of the upper link of the hitch. Keep the plow frame horizontal in longitudinal
level, so as to keep each share in the same plowing depth. If the front share plows deeper
than the rear one, or heel of plow goes out from bottom of furrow, extend the upper link; if
the front share plows shallower than the rear one, or rear heel sinks into the bottom of
furrow, shorten the upper link.
Version 0.2 Page 24 of 52
Jinma 200 series Tractor Users Manual
MCE 2004.01
Adjusting of Lateral Level
Adjust length of right lifting rod to keep plow frame horizontal in lateral level. When the right
lifting rod is extended, the right side of the implement is lowered. As the right lifting rod is
shortened, the rite side of the implement is raised. Usually, the left lifting rod should not
require any adjustment. Only if the right lifting rod is adjusted to its limits will the left
lifting rod need to be adjusted to obtain correct implement placement.
The check chains can make the integral unit have good maneuverability in the field. The check chains also
prevent the implement from hitting the rear wheels when turning the tractor or lifting the implement in the field.
The check chains are normally loosened when the implement is in the plowing position. NEVER tighten the check
chains to adjust the deviation traction of the implement during plowing.
While using implements of driving type, check the length of universal joint shaft; after attachment, there should be
about 10mm axial clearance between PTO shaft and universal shaft.
Using the Differential Lock
In tractor operation, if one drive wheel slips greatly and the tractor can not move forward, operate differential lock
according to the following steps:
•Depress the clutch pedal, move the gear shifting lever to the low range gear position and hold.
•Depress down the differential lock lever under the right side of the seat, gradually release the clutch pedal
to engage the clutch, so that two drive wheels rotate in same speed, then there is a possibility to drive the
tractor through the slippery area.
•After the tractor passes through the slippery area, stop and disengage the differential lock. Do not turn the
tractor with the differential lock engaged otherwise damage to tractor may occur.
Note: Release differential lock lever and let it return to the original position after the differential lock is engaged.
Use of the Electrical Equipment
The electrical equipment of the tractor is used to start the engine, generate power to run all auxiliary electrical
equipment and keep the battery charged. This tractor uses a negative ground 12 volt alternator.
Battery
The battery size is Group 24, 12V and its rated capacity is 66 AH. In routine use, the battery should
be checked often and maintained in accordance with the technical maintenance regulations of the
battery manufacture. Dust and dirt on the outside of the battery should be cleaned away often to
prevent electrical leakages. Check the battery for cracks and electrolyte leaks. Keep the terminals
and all contacts in clean, corrosion free condition. Be sure to keep the air hole on the plastic cover
clear. This will protect the battery from explosion which can be caused by a build up of gas in the
battery. Never allow any open flame or sparks near the battery.
Version 0.2 Page 25 of 52
Jinma 200 series Tractor Users Manual
MCE 2004.01
The Starter
Keep the starter clean and the wire connection lugs in clean and free of corrosion. Do not engage
the starter for longer than 10 seconds at any given time. The shortest interval between two attempts
at starting must be no less than 2 minutes. If the engine can not be started after several attempts,
the trouble should be found and corrected. If the engine is started in cold weather, it should be
preheated with the block heater before starting.

Adjustment of clutch
Due to continuous wear of parts during operation of the clutch, clutch slip and clutch incomplete disengagement
will happen, which can cause the tractor operate incorrectly. Therefore, timely adjustment of the clutch should be
made.
Connection – controlled part dual storage clutch. It mainly consists of three parts: driving part, driven part and
controlling part. Driving part rotates with the engine flywheel; only when the clutch engages can the driven part
rotate with the engine.
Dual stage clutch should be adjusted on fixture. The adjusting steps are as follows: Adjust the length of adjusting
bolt (11) to make the distance difference between 3 release levers and PTO clutch pressure plate is no more than
0.1 mm; after adjustment, tighten it with nut M10x1.
When adjusting the free travel of the clutch pedal ( fig. 4 – 1 ), first adjust the length of clutch push rod ( 15 ) to
ensure that the clearance between end faces of three release levers and release bearing is 2.5 + 0.5 mm and the
idle travel of release rock arm is 3.5 – 5 mm; after adjustment tighten it with nut M10.
Position limit adjustment of working travel of clutch pedal: loosen nut ( 10 ), then turn adjusting bolt ( 11 ) to make
the working travel under release rock arm ( 12 ) is 25 mm, then tighten nut ( 10 ).

Adjustment of brake
After the tractor has worked for a period, the wear of the friction disc of the brake makes the gap between friction
disc and brake drum or friction disc and brake case and brake cover increase and effect the brake performance.
Excessive free travel will cause break ineffectiveness. So the brakes should be regularly checked and adjusted to
ensure the safe operation of the tractor. When one of the following conditions of the brake appears, adjustment
should be done.
•Free travel of brake pedal is excessive and causes brake ineffectiveness.
•Free travel of break pedal is too small and keeps the break in a semi – braking state; the brake case also
generates heat.
•Left and right braking force are unequal.

SERVICE ADVISORIES
50 hour, Head Re-torque
Mike Stuart, a defacto expert on Chinese tractors, recommends to check the head bolt torque on Jinma
tractors when the (1st) 50 hour service is performed. It is simple procedure to perform, and should not
take more than an hour or two. The general procedure is outlined below:
1. Let engine cool to ambient air temp. Locate all
valve cover bolts. The 2cyl engine has 6 bolts
located around the cover edge. The 3 cyl has three
bolts located in the center of the cover. Hood
bracket and electrical items, maybe attached to
some of the bolts. Note orientation and which
bolts have the items. Unscrew and remove all
valve cover bolts. Move electrical items and
brackets aside.
2. Remove valve cover. The valve cover gasket
may break into several pieces, some attached to
cover and rest to head. Use a putty knife to
scrape free of cover and head. Vacuum up the
loose pieces. Locate all head bolts. There are 10
bolts for the 2 cyl engine and 8 for the 3 cyl engine.
3. Check the torque sequence pictures, further down, to verify you found all the bolts.
4. Using the correct torque sequence for your engine, torque
each bolt to 95-105 ft lbs. Note: Do not loosen the bolts
first. You are only tightening them.
5. If you have a new gasket, lightly coat the surfaces with
Permatex Blue RTV Silicone gasket maker, or equivelent.
Align gasket on head, making sure all holes and edges are
aligned. The RTV will
hold the gasket from
slipping.
6. If you do not have a new gasket, you can place a small
continuous bead of the RTV gasket maker around the valve cover
mating surface of the head. Don't over do the RTV such that it
will be squeezed and fall into the top of the head.

7. Align the valve cover over the head. Carefully set it on the head. Use a couple of the valve cover
bolts and just get them started, to keep the cover in position.
8. Get all valve cover bolts started. Make sure you have mounted any bracket or electrical items.
Tighten the valve cover bolts evenly. Start at the center, and work toward the ends. Don't have a
torque spec for the valve cover bolts, but 3/8" socket wrench tight, should do.
9. Start engine, and bring up to operating temperature. Carefully check valve cover for oil leaks.

Keeping the hydraulic pump pre-filter clean is very important to the operation of your tractors
hydraulic system. This filter is located under the drivers seat, feeds the pump that is located on the right
side of the engine which in turn produces pressure for the FEL, Power Steering, and 3 Point system.
This pump is cooled and lubricated by the same oil it pumps and therefor a starvation of the pump due
to restricted flow will most likely cause complete failure or at the very least cause improper wear, early
failure and/or reduced pressure and flow. Indications that your filter is dirty would be either, no or
sluggish loader or power steering operation especially during first start up or cold temperatures. The
manufacturing process can and will allow a significant amount of metal filings or contaminates to be in
the system. Just draining and replacing the oil will not clean the filter. It is our highest
recommendation that this bulletin be followed immediately before any further operation is attempted no
matter what hours are on the engine. Virtually no oil is lost during this procedure. The bulletin is
specifically written for the Q18-28 and is not valid for the 30-35 HP Jinma tractor - See Advisory #2
1. If you have a front end loader make sure it is on the ground and no pressure is in the system. With
tractor turned off move all control valves back and forth to neutralize any pressure.
2. Remove the 4 bolts than hold down the operator seat assembly and remove the seat.
3. Unscrew the nut which holds the steel suction line to the cover/adapter plate atop the reservoir. This
line feeds the inlet side of the hydraulic pump which
is located on the forward/right side of the engine.
4. Remove 3 bolts that hold the cover/adapter plate to
the top of the reservoir.
5. Gently, without harming the gasket lift this entire
assembly up and out of the well. Oil should be near
the top of the housing. Do not re-install a damaged
gasket - make a new one from bulk gasket material
available at any auto parts store.
6. Disassemble this filter assembly completely. Wash all metal components in solvent, and use
compressed air to blow from the inside out, this will clean the wire mesh screen. Do not crush or
deform the wire mesh. If you have damaged this filter or broken the 3 bolt housing then call us
for a replacement - we normally stock these items. Wipe off two rubber gaskets and re-assemble.
(hint; a small amount of axle grease on the gaskets will hold them in place while you reassemble it).
Firmly tighten the bolt into the bottom of the filter assembly and carefully inspect the wire mesh to
confirm it does not have any gaps around the outside on either end. Drop the filter assembly back
into the housing and tighten the 3 bolts and re-attach the suction line.

1. The pump must be primed and will not normally pickup oil from the filter due to air which is now in
the intake line. To aid in priming connect the 2 mid ship
hydraulic quick connects together by disconnecting the FEL
and butt connect them together. This is the same way your
tractor was shipped prior to installing the FEL. If you do not
have an FEL then this is not necessary.
2. Start tractor for approximately 1 minute and check for leaks.
If you listen carefully you should hear the pump pick up oil
almost immediately and prime itself. Shut off the tractor after
1 minute.
3. Re-hook the quick connects in and out of the FEL,
start up the tractor and operate your loader. Shut
down and re-check your oil level. Re-install the
drivers seat.

Service Advisory 3:
Backhoe Hydraulic Fluid Intake Filter
Approximate Time Needed for Service is 1 hour.
Easy - no special tools required.
Your JW03 Backhoe has been designed with the
same filter system as the tractor. This filter is
located on the left side of the BH oil reservoir, and
is also held on by 3 bolts. On this system you will
need a clean bucket to catch the just under 3
gallons of oil so it will not leak out onto the
ground. It is best to drive the right side of your
tractor up on blocks prior to unbolting the filter
assembly as this will aid in getting all the old oil
out of the tank. Check the oil, if it smells burnt, or
is extremely milky then you should replace it. If
your oil looks good and you don't find many
contaminants then you can strain the oil prior to
putting it back in the reservoir. A paint filter works
good for this and helps to remove debris and contaminants that may be in the system.
1. As always when working with any hydraulics.
Shut down the tractor. Move all control levers to
minimize pressure.
2. Lower the left stabilization pad to make access
easier.
3. Remove the nut holding the hydraulic hose going
to the filter housing. Check for compound washer
either in the nut or in a groove located on the
opposite fitting. Remove it and set aside.
4. Loosen and remove the 3 bolts holding the housing in place. Remember the bucket to catch oil.

5. Remove the filter assembly. Disassemble this filter assembly completely. Wash all metal
components in solvent, and use compressed air to blow from the inside out, this will clean the wire
mesh screen. Do not crush or deform the wire mesh. If you have damaged this filter or broken
the 3 bolt housing then call us for a replacement - we normally stock these items. Wipe off two
rubber gaskets and re-assemble. (hint; a small amount of axle grease on the gaskets will hold them
in place while you reassemble it). Firmly tighten the bolt into the bottom of the filter assembly and
carefully inspect the wire mesh to confirm it does not have any gaps around the outside on either
end.
6. Reinstall the filter assembly (don't forget the gasket) back into the tank and tighten the 3 bolts. Now
put the compound washer back into the groove of the threaded fitting. If you didn't have one to begin
with then a properly fitted rubber O-ring will suffice or you can purchase them from our parts stock.
Be sure to coat an O-ring with grease to prevent pinching. Grease also works good to keep the
compound washer in place while assembling. This washer is necessary to prevent air intake and
leaks to the otherwise closed system. This same compound washer is used in many of your hydraulic
fittings so is best to keep some spares around.

Service Advisory 4:
Injector Pump Oil
Approximate Time Needed for Service is 20 min.
Easy - no special tools required. http://www.tractor-outlet.com/toservice.html
You should check your fuel injection pump oil regularly and change it yearly. The oil is for splash
lubrication of the steel balls and other moving parts inside the mechanical governor. We have found
that hydraulic or engine oil is acceptable for use.
The fill plug (A) is toward the rear of the injector pump and is mounted on top with a breather. The
drain (C) is on the bottom. Total oil volume is about 4 oz. or 1/4 of a pint if completely empty.
To fill and check, first remove the (A) breather on top, then remove the rubber cap (not always
included) from bottom of (B) and add oil very slowly, one ounce at a time. When oil comes out (B)
then it is full. Wait a full 15 minutes for excess oil to run out prior to starting engine. Once oil has
stopped then replace rubber cap (B) and breather (A).

Service Advisory 5:
Oil Drains
Easy - no special tools required.
Figure 33. Transmission Oil Drain Figure 34. Engine Oil Drain
Figure 35. Hydraulic System Oil Drain
Draining and Changing your oils is fairly straight forward and easy. Above we have shown you the
drain locations for each system. Your engine uses standard weight oils. We use HD 30 but 10-40 and
other weights will work also. Use what ever weight oil you are running in your vehicles which would
be appropriate for your local temperature conditions. The transmission and hydraulic system use the
same oil. Choose a quality hydraulic oil such as #303 from New Holland.

Service Advisory 6:
Ignition Switch Retrofit
Easy - no special tools required. http://www.tractor-outlet.com/toservice.html
The ignition switch that came with your Jinma 18-28 HP tractor is multifunction and can present some
problems after significant use. It can have intermittent faults where the momentary glow plugs and
starter are immediately on when you turn the key to the first position (lights). In other words, all three
posts are hot, #2 for lights, #3 for glow plugs, and #4 for starter solenoid. This will cause your 30 amp
fuse to blow consistently. A replacement switch is available through your local New Holland dealer and
was used on Ford Series 2000-9000 tractors from about 1965 on. Ask for Ford Part # D 5NN11N501A.
If you would still like to use a direct replacement that requires nothing other than wire for wire
exchange then we normally stock them. Ask for Jinma part number #TY290

Before you start assembling your “C rate” tractor, please take some time to look over the
owners manual and illustrated parts manual that is in the Blue “ tool and spare parts” box.
Decades of hands on work on foreign equipment has taught me some rules that I would l
ike to pass along.
•Positive Mental Attitude
•Do not be looking for “ problems” because it is Chinese. Most tractors arrive with none
and the minor ones you encounter are NORMAL for any new equipment.
•Part A was scratched in shipment!!!
•Brand name Orange, Green and Blue tractors are assembled from “ Crate” parts and minor
imperfections are repaired and the tractor is sent to a dealer. A traditional dealer inspects
the tractor and fixes any additional operational, fit and finish defects before the customer
sees the equipment. You are the DEALER AND ASSEMBLY FACILITY. This is part of
why you are saving a LOT of money. A missing bolt, a bent line or a scratch are items
you will take care of for your customer (YOU) to make sure that his machine is as good as
it can be.
•Don't overlook the small stuff
•Take your time assembling and checking your tractor. The more items you check during
assembly the fewer problems you will have later. Check that the bolts everywhere are
tight. A wire tie to secure hoses and wires now means less leaks and electrical problems
for the life of your tractor.
•The D*@N *%@~ does not work!
Relax. I know the frustration after waiting so long for your tractor to arrive when
something does not work or is really broken.
•If it does not work have you read the owners manual? It may have bad English but it does
have good trouble shooting help.
•Defective Parts have a factory one year parts warranty. If we do not have the parts in stock
we may,
•Buy part from another dealer.
Repair your part.
Get part from factory.
You will get your tractor running.

I can't stress enough that you should relax, take your time, read and look at the pictures in
the parts and owners manuals and have fun. Get help when you need it and DO IT SAFE. When
you are done you will know more about your tractor than most owners and some DEALERS. I
hope you will have pride in knowing that the best assembly facility put your tractor together.

Jinma JW-03 Backhoe Info
The following info has been provided by Schmalts, Jay, and Jeff. JW-03 Backhoe owners and
frequent contributers to the CTOA board.
PIVET PINS
The hoe is great! If you don't plan to use it for any really heavy duty digging, it would be fine as
is. But, who the heck is going to do that??? If you do these mods you will have a hoe that
BLOWS AWAY any competitors, for less than half the price. These mods will not take very
long, if you have a welder and metal cutter of some kind. These hoes have a huge bucket and
rams, they are too strong for the sub-frame setup, from the factory. Even with these issues, I
recommend one to anyone looking for a hoe.
1).Prevent pivot pins from popping out. The
existing middle section pins can pop out when a
twisting force is applied. Get some 1/2" x 1/4"
bar stock and weld a piece of it across the open
part of the booms, near the pivot pins, in the
center section. (see yellow arrows)
There is one pin that needs it the most. If you
look at the pins, you will see the one that is in
the mid-section joint does not go through very
far. It barely protrudes out the other side and
does not have a snap ring holding it in, just a S-
shaped hook. I put the little piece of metal across the open area on top of the boom to keep it
from spreading, and tacked in the pin, with a few small welds. If you have to remove the pin
latter, a quick pass with a grinder will take of the tack welds.

Enlarge outrigger pads.
2. The small pads that come with the hoe are no good for
soft soil and sink easily. (see circle diagram) This intern
puts stress on the tractor frame.
Weld 4- 5"x 5"x 1/4" plates to the underside corners of
each pad. Eight in all. If you go to a metal supplier this
should cost around $20 to have it sheared to size.
Strengthen lower sub-frame.
3. The lower sub-frame of the hoe will bend if you try to lift the whole tractor off the ground
with the hoe. (see what can happen in picture below) Weld some square tubing along the
bottom of the frame to stiffen it up.
Note: New JM hoe frames are said to be improved in this area. Square tubing below the oval cut-
out has been added. Still not as strong as the mod shown here.
