6. Install tooling (A) as shown. 7. Install tooling (B) and a nylon strap on steering and implement pump (11). Attach tooling (A) to the nylon strap and tooling (B). If the pump drive gear slides out with the pump, put it back into the flywheel housing before tilting the pump and adapter for removal.8. Remove six bolts (9), and remove adapter (10) and steering and implement pump (11) as a unit. Use tooling (A) to tilt the pump 90°. The weight of the adapter and steering and implement pump unit is 100 kg (220 lb). 9. Remove O-ring seal (12) from adapter (10).10. Remove four bolts (13), and remove adapter (10) and the O-ring from steering and implement pump (11). 11. Remove fittings (8) and (15), elbow (14) and the O-ring seals from the steering and implement pump. The following steps are for the installation of the steering and implement pump.12. Install fittings (8) and (15), elbow (14) and the O-ring seals on the steering and implement pump.13. With the O-ring seal in place, position adapter (10) on steering and implement pump (11) and install four bolts (13). Tighten bolts (13) to a torque of 365 N m (275 lb ft).14. Install O-ring seal (12) on adapter (10). Put clean oil on the seal.15. Use tooling (A) and (B) to position adapter (10) and steering and implement pump (11) as a unit on the flywheel housing, and install six bolts (9). Remove tooling (A) and (B).16. Position the seal and elbow (2) on the pump, and install the four bolts that hold it in place.17. Connect hose assemblies (1), (3), (4) and (5) to the steering and implement pump.18. Connect hose and tee assembly (7) to fitting (8).
The steering and implement pump case must be full of oil before starting the engine. Pump damages will occur if not filled with oil.
19. To fill the steering and implement pump case with oil, disconnect hose assembly (1) from fitting (6) and use a funnel to slowly pour hydraulic oil into hose (1). When oil runs out of fitting (6), the steering and implement pump and steering motor are full of oil. Connect hose assembly (1) to fitting (6).20. Install the rear bottom guard.21. Fill the hydraulic tank with oil to the correct level. See the Maintenance Manual.End By:a. install counterbalance valveDisassemble Steering And Implement Pump
