Install 231587 Pump Group. The 1418209 Couplingmay be reused if in good condition. Replace 1178801 Seal O-ring betweenImplement pump and Steer pump. Reconnect suction line.
Note: Refer to Illustration 2, 2388681Pump Group ? Mounting, for pump orientation, mounting hardware, and additionalinformation required in the following steps.
Install 2409019 Bracket Assembly to rear of 2316587Implement Pump.
Install 2404730 Hose Assembly between Steer pumpcase drain and 2316587 Implement pump bearing drain.
Note: Refer to Illustration 2 andSection B-B for fitting and seal information and orientation of the hose.
Install 2406847 Implement pump discharge TubeAssembly.
Note: Refer to Illustration 2 and SectionB-B.
Pre-fill the Implement, Steering, Pilot and Brakepumps with recommended hydraulic oil before installing cab. Always useclean oil when you add oil to the system. Clean oil must be at an ISO levelof at least 16/13.
Install Cab. Refer to Disassembly and Assembly,"Cab ? Install". Tighten the four cab mounting bolts to a torque of 850+/- 100 N.m (629 +/- 74 lb. ft.).
Before starting engine, fill hydraulic tank withrecommended hydraulic oil. Always use clean oil when you add oil to thesystem. Clean oil must be at an ISO level of at least 16/13.
Crank the engine at least five times without startingthe engine. Wait for at least five seconds between cranks in order to allowthe oil to flow smoothly through the system.
Check the oil level in the hydraulic tank. Ifnecessary, refill the tank.
Start the engine at LOW IDLE. Allow the engineto run for several seconds. Stop the engine.
Check the oil level in the hydraulic tank. Ifnecessary, refill the tank.
Start engine and maintain low idle. Maintainhydraulic oil level until it reaches the full mark on hydraulic oil levelsite gauge.
Cycle, AT LOW IDLE, the tilt cylinder aminimum of three times. DO NOT ALLOW THE CIRCUIT TO GO INTO RELIEF.
Check the oil level in the hydraulic tank. Ifnecessary, refill the tank.
Cycle, AT LOW IDLE, the lift cylindersa minimum of three times. DO NOT ALLOW THE CIRCUIT TO GO INTO RELIEF.
Check the oil level in the hydraulic tank. Ifnecessary, refill the tank.
Cycle, AT LOW IDLE WITH FRAME LOCK INSTALLED,the steering circuit to
