COVER 2346614 - Caterpillar

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.
Apply Tooling (G) 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 41 kg (90 lb).
Use Tooling (J) to compress the springs.

Position retainer (3) on sprocket (5) with no shims installed. Install bolts (2) finger tight against retainer (3). Tighten bolts (2) to a torque of 80 N m (59 lb ft). Repeat until bolts (2) no longer turn. Rotate the housing three full rotations. Bolts (2) will have to be tightened to a torque of 80 N m (59 lb ft) several times. After each tightening sequence, rotate the housing three full revolutions until the bolt torque has equalized at 80 N m (59 lb ft).
Loosen bolts (2), and finger tighten against retainer (3).
With bolts (2) finger tight only, rotate the housing three full rotations.
Tighten bolts (2) to a torque of 20 N m (177 lb in). Repeat until bolts (2) no longer move. Rotate the housing three full revolutions. Bolts (2) will have to be tightened to a torque of 20 N m (177 lb in) several times. After each tightening sequence, rotate the housing three full revolutions until the bolt torque has equalized at 20 N m (177 lb in).
Using Tooling (K) to measure for dimension (X) in three places. Calculate the average dimension for the three measurements and subtract the thickness of retainer (3).
Add 0.064 mm (0.0025 inch) to the dimension calculated in Step 19. The result will be the total thickness of shim pack (4).
Build shim pack (4) to the dimension calculated in Step 20. Use the most number of thick shims possible for the given total thickness. Position the thin shims between the thick shims.
Install retainer (3). Apply Tooling (H) to bolts (2). Install bolts (2) and tighten to torque of 270 40 N m (200 30lb ft)

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).
