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. • Wash all metal parts in clean solvent. • Cleanliness is extremely important. • Use compressed air to dry the parts. Do not wipe them dry with paper towels or cloth. • 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. 2 • The compressed air should be filtered and moisture free. • Always use new seals when reassembling hydraulic pumps. EATON 350 Series Dual Path Mobile Pumps E-PUPI-TS006-E September 2007 • 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.

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. Slide the spring (item 6) and springstop over the bolt so that both parts rest on the spring retaining washer. Place the second spring retaining washer (item 2) over the servo piston bolt, with the stamped word “IN” facing the spring. Step 5 Step 6 Step 8 Step 9 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. Insert the servo piston bolt assembly into the piston (item 1), threaded end first. 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. Tighten the piston plug (item 3) to 71±3 n/m (52.4±2.2 lb-ft). 30 Step 7 Note: If assembling a HRC controlled pump, a second spring will be installed in place of the displacement limiter.

EATON 350 Series Dual Path Mobile Pumps E-PUPI-TS006-E September 2007 Assembly Servo Piston/ Dual Pump Housing Assembly Dual Pump Housing Assembly Step 10 Step 12 Step 1 Step 2 Thread a locking nut (item 8) onto the servo piston bolt until it fits against the spring compression nut. 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 servo piston bolt should turn freely but should not move in or out of the servo piston. Place the center housing on a stable work surface. Using snap-ring pliers, insert a snap ring 16077-33 in each of the two grooves inside the bearing bore. Step 3 Step 4 Step 5 Step 6 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. Insert a Teflon glide ring 5987241-001 in the same way, so that it fits in the seal groove inside the backup ring. Using the same method, install backup rings and Teflon glide rings in the other side of the servo piston bore. 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 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.

It prevents the chance of damaging the unit which might occur if the system was not properly purged of air before start-up. 44 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 reservoir and refill if necessary to the proper level with an approved filtered oil. EATON 350 Series Dual Path Mobile Pumps E-PUPI-TS006-E September 2007 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.
