Introduction

This manual provides service information for the Eaton Model 350 Series Piston Pumps. Step-by-step instr uctions 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 thoroughly 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.

Assembly

Swash Plate Sub-Assembly

Step 1

Press 15mm diameter dowel pin (item 5) into opening at end of swash arm (item 2).

Step 2

Insert 2 Drive-Lok dowel pins (item 6) into smooth-bore holes in swash plate (item 1).

Step 3

Align smooth-bore holes in flat surface of swash arm with Drive-Lok pins; fit swash arm to swash plate and press parts togetherwith an arbor press.

Step 4

Place assembled swash plate and swash arm on a stable work surface, with swash arm pointing up.

Step 5

Fit together two Nord-Lock washers (it em 3 ) s o th a t the stepped faces match, and the faces with radial teeth face out. Assemble another pair of washers the same way.

Step 6

Place one pair of washers on each shoulder of the swash arm, aligned with the threaded holes.

Step 7

Insert an M10 x 1.25 x 40mm socket-head cap screw (item 4) through each pair of washers and into threads; tighten to 79 n/m (58 lb/ft).

Note:

Disassembly of the Swash Plate and Manual Servo Controller is the reverse of the assembly processes outlined starting on page 25 in this manual.

Step 9

Align the center hole on the feedback link with the dowel pin on the control spool. Press the feedback link (item 6) onto the dowel pin until the end of the dowel pin is flush with the surface of the feedback link.

Step 10

Fit an O-Ring (item 4) under the head of a threaded retaining plug (item 3). Lubricate the O-Ring.

Step 11

Align the 6.35mm groove in the control input shaft with the threaded hole on the control housing.

Step 12

Insert the retaining plug (item 3) in the threaded hole; make sure the plug fits in the 6.35mm groove. Tighten to 11 n/m (8 lb-ft).

Step 13

Fit an O-Ring (item 9) in the center groove on a spool bore plug (item 8). Insert the plug, threaded end first, in the spool bore; it should fit around the spring end of the spool shaft sub-assembly.

Step 14

Using adjustable-grip pliers, turn the spool bore plug until there is no play where the spool shaft meets the feedback link. Adjust tightness as needed; both under-tightening and over-tightening the plug will result in unwanted play.

Step 15

Insert a 4.7mm set screw (item

10) in the threaded hole near the end of the spool shaft port. Tighten to 3 n/m (2.2 lb-ft).

Step 16

Fit a control input shaft seal (item 5) over the exposed end of the control input shaft; using a seal installation tool, press down on the seal until it is flush with the face of the input shaft port. (Note: If necessary, use a shaft coupler to press the seal into place).

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 41cc (2.50 cid) - 4994911-001

Insert the pivot into the shoe retainer from beneath so that the tapered faces match.

Holding the pivot in place, lower the piston assemblies into their respective cylinders. The pivot should rest on the three loading pins.

Servo Piston Assembly

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.

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), threadedend 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.

Step 9

Step 3

Compress a piston backup ring 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

Insert a Teflon glide ring 5987241-001 in the same way, so that it fits in the seal groove inside the backup ring.

Step 5

Using the same method, install backup rings and Teflon glide rings in the other side of the servo piston bore.

Step 6

Lubricate the leading edge of a servo piston assembly, and insert it in the piston bore. The threaded servo piston bolt should extend about 20mm (.80 in) beyond the housing.

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 compression nut. The ser vo piston bolt should turn freely but should not move in or out of the servo piston.

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 damaging the unit which might occur if the system was not properly purged of air before start-up.

1. After the transmission components 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 filtered through a 10 micron filter. 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 seconds. Diesel engines: shut off the fuel flow to the injectors and turn the engine over for 15 seconds.

5. Replace the coil wire or return the fuel flow to the injectors. Place the transmission unit in the neutral position, start the engine and run it at a low idle. The charge pump should immediately pick up oil and fill the system. 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 system 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 operation. 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.
