Typical example
If necessary, follow Step 1.a through Step 1.d to install gear (18) to the air compressor.
Ensure that the shaft of air compressor (6) is clean, free from damage, and dry. Ensure that gear (18) is clean and free from damage and dry.
Install gear (18) and a new spring washer (19) to the shaft of the air compressor.
Apply Tooling (D) to the threads of the shaft. Install nut (20) to the shaft of air compressor (6).
Use a suitable tool to prevent the shaft of the compressor from rotating. Tighten nut (20) to a torque of 9 N m (80 lb in).
If necessary, install hose assembly (23) to the connection on the cylinder block. Align hose assembly with the temporary marks. Tighten nut (22) to a torque of 120 N m (89 lb ft).
Use Tooling (E) to lubricate a new O-ring seal (21). Install the O-ring seal to air compressor (6).
Use Tooling (A) to rotate the crankshaft so that number one piston is at the top center position on the compression stroke. Refer to Systems Operation, Testing and Adjusting, "Finding Top Center Position for No.1 Piston" for the correct procedure.Note: The air compressor must be timed with the engine to minimize engine vibration.

Typical example
Rotate the crankshaft of the air compressor until timing Mark (Y) is aligned with timing Mark (Z) on the rear face of the air compressor.
If necessary, install studs (14) to the front housing. Tighten the studs to a torque of 25 N m (221 lb in).
Align air compressor (6) with studs (14). Install the air compressor to the front housing. If necessary, rotate the crankshaft of the air compressor to allow the gears to align.
Install nuts (15). Tighten the nuts to a torque of 78 N m (58 lb ft).
If necessary, follow Step 10.a through Step 10.c to install cover (16).
Use Tooling (E) to lubricate a new O-ring seal (13). Install the O-ring seal to cover (16).
Install plate (16) to the air compressor.
Install bolts (17). Tighten the bolts to a torque of 16 N m (142 lb in).

Position support bracket (11) onto air compressor (6). Install bolts (10) finger tight.
Install bolts (12) finger tight.
Tighten bolts (10) to a torque of 22 N m (195 lb in).
Tighten bolts (12) to a torque 44 N m (32 lb ft).Note: Ensure that the air compressor is not stressed as the bolts are tightened.
