Separate the track. b. Remove the steering motor. c. Remove the axles. Personal injury can result from hydraulic oil pressure and hot oil.
the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Illustration 1 g00992346 1. Remove bolts (1). Illustration 2 g00992348 2.

Attach Tooling (C) and a suitable lifting device to the final drive, steering differential, and brake (left side). The weight of the final drive, steering differential, and brake (left side) is approximately 680 kg (1500 lb). Illustration 5 g00992350
g06101043 7. Attach Tooling (D) to Tooling (B) and Tooling (C). 8. Separate the final drive approximately 152 mm (6.0 inch). 9. Release the pressure on Tooling (D). Rotate the brake housing 90 degrees in the counterclockwise direction. Illustration 7 g00992352 10. Rotating the brake housing allows pinion (7) to point forward. Rotating the brake housing will allow the final drive to swing toward the front of the machine. Rotating the brake housing will allow clearance for the ring gear to clear the machine. Remove the final drive, steering differential, and brake (left side). Installation Procedure 1. Install the final drive, steering differential, and brake (left side) in the reverse order of removal. a. Apply SAE 30W lubricant to the threads of bolts (6). Tighten bolts (6) to a torque of 175 ± 40 N·m (129 ± 30 lb ft). Then, tighten bolts (6) by an extra 1/3 turn. The final torque of bolts (6) should be a minimum of 380 N·m (280 lb ft).
