Typical example
If necessary, follow Step 1.a through Step 1.b in order to install the gear to the air compressor.
Ensure that the shaft of air compressor (4) is clean and dry. Ensure that gear (16) is clean and free from damage.
Install gear (16) and a new spring washer to the shaft of the air compressor.
Apply Tooling (D) to the threads of the shaft. Install nut (17) to the shaft of air compressor (4). Tighten the nut to a torque of 120 N m (89 lb ft).
Install the O-ring seal (18) to air compressor (4). Use Tooling (E) in order to lubricate the O-ring seal.
Ensure that number one piston is at the top center position on the compression stroke. Refer to the Systems Operation, Testing and Adjusting, "Finding Top Center Position for No. 1 Piston". Note: The air compressor must be timed with the engine in order to minimize engine vibration.

Refer to Illustration 7 for air compressors with a SAE drive. Refer to Illustration 8 for air compressors with a DIN drive.
Install nuts (13). Tighten the nuts to a torque of 78 N m (58 lb ft).
If necessary, follow Step 9.a through Step 9.c in order to install cover (14).
Install a new O-ring seal (11) to cover (14). Use Tooling (E) in order to lubricate the O-ring seal.
Install cover (14) to air compressor (4).
Install bolts (15). Tighten the bolts to a torque of 13 N m (9.5 lb ft).
