Introduction

This manual provides service

information for the Eaton

Model 350 Series Piston

Pumps. Step-by-step instructions

for the complete assembly

of the pump are given. For

dis-assembly, follow the reverse

of the assembly instructions.

These recommendations

should be followed to insure

successful repairs.

• Remove the pump from the

vehicle.

• Cleanliness is extremely

important.

• Clean the port areas thor-

oughly before disconnecting

the hydraulic lines.

• Plug the pump ports and

cover the open hydraulic

lines immediately after

they’re disconnected.

• Drain the oil and clean the

exterior of the pump before

making repairs.

• Wash all metal parts in

clean solvent.

• Use compressed air to dry

the parts. Do not wipe them

dry with paper towels or

cloth.

• The compressed air should

be filtered and moisture

free.

• Always use new seals when

reassembling hydraulic

pumps.

• Lubricate the new rubber

seals with a petroleum jelly

(Vaseline) before installation.

• Torque all bolts over gasketed

joints, then repeat torquing

sequence to make up for

gasket compression.

• Verifying the accuracy of

pump repairs on an authorized

test stand is essential.

cylinder barrel. Install the three

pins (item 6) with head end to

the inside of the barrel and

position in the special grooves

of the cylinder barrel spline.

Step 2

Install the washer, spring, and

second washer into the cylinder

barrel. Use the two 3/8 in. I.D.

washers, nut and 3/8 in. x 3-1/4

in. cap screw to compress the

spring and retain with retaining

ring. Remove the nut, cap

screw, and the two washers.

Step 3

Install the pivot (item 3) onto

the three pins, shoe retainer

onto he pivot, and piston

assemblies thru the shoe

retainer and into cylinder

barrel, resting on shoe

retainer.

Step 4

Insert (9) piston assemblies

the tapered faces match.

Holding the pivot in place,

lower the piston assemblies

into their respective cylinders.

The pivot should rest on the

Step 1

Hold a servo piston bolt (item 4)

head end down, on a work

surface.

Step 2

Slide a spring retaining washer

(item 2) onto the servo piston

bolt so that the stamped word

“IN” faces up, toward where

the spring will go.

Step 3

Slide the spring (item 6) and

springstop over the bolt so that

both parts rest on the spring

retaining washer.

Note: If assembling a HRC

controlled pump, a second

spring will be installed in place

of the displacement limiter.

Step 4

Place the second spring retaining

washer (item 2) over the servo

piston bolt, with the stamped

word “IN” facing the spring.

Step 5

Thread a spring compression

nut (item 7) onto the servo

piston bolt, with the inside

counterbored (smooth) end

facing the spring. Tighten the

spring compression nut until

it is snug against the spring

retaining washer.

Step 6

Insert the servo piston bolt

assembly into the piston (item 1),

threaded end first.

Step 7

Thread a piston plug (item 3) into

the open end of the servo piston.

Step 8

Using a vise and two pieces

of shim stock, grip the piston by

the recessed groove. Do not

mar the rounded surfaces of

the servo piston.

5987241-001 and insert it in the

servo piston bore, which is

perpendicular to the bearing bore;

let the backup ring expand into

the seal groove.

Step 4

Step 5

Using the same method,

install backup rings and Teflon

glide rings in the other side of

Step 6

Lubricate the leading edge of

a servo piston assembly, and

insert it in the piston bore. The

Step 10

Thread a locking nut (item 8)

onto the servo piston bolt

until it fits against the spring

compression nut.

Step 11

Apply one drop of Loctite 290

to the threads of the servo

piston bolt where the spring

compression nut and locking

nut will meet.

Step 12

This step may require two people:

Using a 5mm hex key, hold the

servo piston bolt steady, then

use two 9/16-inch open-ended

wrenches to tighten the locking

nut against the spring compres-

sion nut. The servo piston bolt

should turn freely but should

not move in or out of the

servo piston.

Step 1

Place the center housing on a

stable work surface.

Step 2

Using snap-ring pliers, insert a

snap ring 16077-33 in each

in each of (6) holes in the

controller housing.

Step 43

Place the controller gasket

5987239-001 over the exposed

ends of the cap screws.

Step 44

Lift the controller housing

toward the controller mounting

face, taking care not to let the

gasket or screws fall.

Step 45

Align the feedback link inside

the controller housing with the

feedback pin extending from the

mounting plate. Tighten the

screws to 14 n/m (10.3 lb-ft).

Displacement Limiters

Step 46

If the pump includes displace-

ment limit ports, insert a

displacement limiting screw

16139-644 in each of the two

larger ports.

Step 47

Install a sealing nut 5996839-

001 over each displacement

limiting screw and tighten to

16 n/m (11.8 lb-ft).

Step 48

Repeat this process for the two

smaller displacement limit ports,

tightening the sealing nuts

5996838-001 to 9 n/m (6.6 lb-ft).

Step 49

Seal unused ports with appro-

priate plugs.

System/Charge Relief Valve Pressure Settings

Inlet Vacuum 0,203 bar [6 inHg] max.

Case Pressure 1,7 bar [25 PSI] maximum

Charge Pressure 17,24 to 20,68 bar

[250 to 300 PSI]*

System Pressure 345 bar [5000 PSI] maximum**

207 bar [3000 PSI] continuous

*Min: 13.8–17.2 Bar [200–250 psi], Max: 27.6–31 Bar [400–450 psi]

**380 Bar [5500 psi] Max, 276 Bar [4000 psi] Continuous

The high pressure relief valves are all factory preset and cannot

be readjusted.

The pressure setting is stamped on each valve with a three digit

number. To identify, multiply the noted number by 10 to get the

valves pressure setting.

Example: 10 x 500 = [5000 PSI] 345 bar

Start-Up

Procedure

When initially starting a new or

a rebuilt transmission system, it

is extremely important that the

start-up procedure be followed.

It prevents the chance of dam-

aging the unit which might

occur if the system was not

properly purged of air before

start-up.

1. After the transmission com-

ponents have been properly

installed, fill the servo pump

housing at least half full with

filtered system oil. Connect

all hydraulic lines and check

to be sure they are tight.

2. Install and adjust all control

linkage.

3. Fill the reservoir with an

approved oil that has been fil-

tered through a 10 micron fil-

ter. Refer to Eaton Technical

Data sheet number 3-401

titled Hydraulic Fluid

Recommendations.

4. Gasoline or L.P. engines:

remove the coil wire and turn

the engine over for 15 sec-

onds. Diesel engines: shut

off the fuel flow to the injec-

tors and turn the engine over

for 15 seconds.

5. Replace the coil wire or

return the fuel flow to the

injectors. Place the transmis-

sion unit in the neutral posi-

tion, start the engine and run

it at a low idle. The charge

pump should immediately

pick up oil and fill the sys-

tem. If there is no indication

of fill in 30 seconds, stop

engine and determine the

cause.

6. After the system starts to

show signs of fill, slowly

move pump swashplate to a

slight cam angle. Continue to

operate system slowly with

no load on motors until sys-

tem responds fully.

7. Check fluid level in the reser-

voir and refill if necessary to

the proper level with an

approved filtered oil.

8. Check all line connections for

leaks and tighten if necessary.

9. The machine is now ready to

be put into operation.

10. Frequent filter changes are

recommended for the first

two changes after placing

the machine back into opera-

tion. Change the first filter in

3-5 hours and the second at

approximately 50 hours.

Routinely scheduled filter

changes are recommended

for maximum life of the

hydraulic system.
