If necessary, follow Step 18 through Step 18.c in order to install adapter (25) to air compressor (6).
Use Tooling (E) in order to lubricate a new O-ring seal (26). Install the O-ring seal to air compressor (6).
Position adapter (25) onto air compressor (6).
Install bolts (27) to air compressor (6).
Tighten bolts (27) to a torque of 78 N m (58 lb ft).
If necessary, follow Step 2.a through Step 2.d in order to install gear (21) to the crankshaft of the air compressor.
Ensure that the crankshaft of air compressor (6) is clean and dry. Ensure that gear (21) is clean and free from damage.
Install gear (21) and a new spring washer (23) (not shown) to the crankshaft of the air compressor.
Apply Tooling (D) to the threads of the crankshaft. Install nut (22) to the crankshaft of air compressor (6).
Use a suitable tool in order to prevent the crankshaft of the compressor from rotating. Tighten nut (22) to a torque of 190 N m (140 lb ft).
Use Tooling (E) in order to lubricate O-ring seal (24). Install the O-ring seal to air compressor (6).
Use Tooling (A) in order 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, "Fuel Injection Timing - Check" for the correct procedure. Note: The air compressor must be timed with the engine in order to minimize engine vibration.

If necessary, install studs (17) from the front housing. Tighten the studs to a torque 25 N m (221 lb in).
Align air compressor (6) with studs (17). Install the air compressor to the front housing. If necessary, rotate the crankshaft of the air compressor in order to allow the gears to align. Note: Ensure that timing Mark (Y) is aligned with timing Marks (Z). Refer to Illustration 10 for the correct position of timing marks.
Install nuts (18). Tighten the nuts to a torque of 78 N m (58 lb ft).
If necessary, follow Step 11.a through Step 11.c in order to install cover (19).
Use Tooling (E) in order to lubricate a new O-ring seal (16). Install the O-ring seal to cover (19).
Install cover (19) to air compressor (6).
Install bolts (20). Tighten the bolts to a torque of 16 N m (142 lb in).
