This document provides instructions for removing and repairing a drive axle, differential, and wet disc brakes on a service vehicle. It describes removing the drive axle by draining fluids, disconnecting lines and hoses, and removing mounting hardware. It then details disassembling the planetary gear assembly within the drive axle by removing retaining rings, gears, seals, and bearings. Finally, it outlines disassembling the wet disc brakes by removing mounting screws, pistons, springs, plates, and discs.

WARNING
When putting the lift truck on blocks, make
sure the surface is solid, even, and level. Any
blocks used to support the lift truck must be
solid, one-piece units.
1. Put blocks on each side (front and back) of the
steering tires to prevent movement of the lift
truck.
2. Raise the lift truck and put blocks under the
frame so that the drive wheels do not touch the
floor. Put blocks under the counterweight for
stability.
3. Remove the mast assembly as described in the
section Mast Repairs, 2- and 3-Stage Masts
4000 SRM 1250.
4. Remove the wheels.
5. Remove the planetary carrier cover fill/drain
plugs on both sides of the drive axle and drain
the oil into a suitable container. See Figure 2.
6. Remove the drive axle main housing center fill/
level plug. See Figure 2.
7. Remove the oil fill plugs on both sides of the drive
axle. See Figure 2.
8. Remove the oil drain plugs on both sides of the
drive axle and drain the oil into a suitable con-
tainer. See Figure 2.
9. Remove the drive axle main housing center drain
plug and drain the oil into a suitable container.
See Figure 2.
10. Remove the parking brake cables. Refer to the
section Brake System 1800 SRM 1247.
11. Disconnect the brake supply line from the brake
line cross fitting on the drive axle. See Figure 3.
12. Disconnect the brake booster supply line from
the manifold on the drive axle. See Figure 3.
13. Disconnect the brake booster return line from the
manifold on the drive axle. See Figure 3.
14. Disconnect the drive axle to transmission cooling
return hose from the manifold on the drive axle.
See Figure 3.
15. Disconnect the transmission to drive axle cooling
supply hose from the manifold on the drive axle.
See Figure 3.
