   Personal injury can result from being struck by parts propelled by a released spring force. Make sure to wear all necessary protective equipment. Follow the recommended procedure and use all recommended tooling to release the spring force.

10. Apply Tooling (H) onto the mating surface of the housing. Use Tooling (A) and a suitable lifting device to install cover (9). The weight of cover (9) is approximately 42 kg (93 lb).

11. Use Tooling (J) to compress the springs.

    Note: For Steps 15 to 21, use two standard bolts placed 180° apart.

15. Position retainer (3) on sprocket (5) with no shims (4) installed. Thread Tooling (K) finger tight against retainer (3). Tighten first bolt followed by the second to a torque of 90 N·m (66 lb ft). Repeat until neither bolt turns. Rotate the housing three full rotations once the bolt torque has equalized at a torque of 90 N·m (66 lb ft). Tooling (K) will have to be tightened several times followed by three full rotations to equalize at the correct torque.

16. Loosen Tooling (K) and retighten finger tight against retainer (3).

17. With Tooling (K) finger tight only, rotate the housing three full rotations.

18. Tighten the first bolt followed by the second bolt to 30 N·m (22. lb ft). Repeat until neither bolt turns. Rotate the housing three full rotations once the bolt torque has equalized at 30 N·m (22 lb ft). Tooling (K) will have to be tightened several times followed by three full rotations to equalize at the correct torque.

19. Measure Dimension (X) shown in Illustration16 . Add 0.02 mm (0.001 inch) to the average of Dimension (X). The result is the required thickness of shim pack (4).

20. Build shim pack (4) to the thickness calculated in Step 19. Use the most number of thick shims possible for the given total thickness. Position the thin shims between the thick shims.

21. Install shim pack (4) and install retainer (3). Apply Tooling (L) to bolts (2). Install bolts (2) and tighten to a torque of 270 ± 40 N·m (199 ± 30 lb ft).

22. Use Tooling (A), Tooling (C), and a suitable lifting device to remove service brake (1) from Tooling (B). The weight of service brake (1) is approximately 272 kg (600 lb).

23. Install nut (24) onto compensator (26) snug nut (24) against compensator (26) shoulder. Apply air pressure, to the brake piston. Tighten compensator (26) by hand until the compensator contacts the piston. Measure the distance between nut (24) and housing face (27), record this distance as Dimension (z).

24. Subtract 4.3 mm (0.169 inch) from Dimension (z) and round down to the nearest 0.5 mm (0.02 inch) to achieve the required number of shims.

25. Remove compensator (26) and nut (24) from housing.

26. Release air pressure from the brake piston.

27. Install the required number of shims (23) to compensator (26), up against nut (24).

28. Install O-ring (25) onto compensator (26).

29. Install compensator (26) by hand until the compensator contacts the piston. Loosen compensator (26) 1/2 of a turn.

30. Hold compensator (26) and tighten nut (24) to a torque of 50 ± 10 N·m (37 ± 7 lb ft).

End By:

1. Install the service brake (wheel spindle).
