Install air duct (5) to turbocharger (8) and turbocharger (3).
Install bolts (7) to air duct (5). Tighten the bolts to a torque of 22 N m (195 lb in).
Ensure that elbow (1) is clean and free from wear and damage. If necessary, replace the elbow.
Use Tooling (A) to lubricate the Allen head bolt for V-band clamp (9). Position V-band clamp (9) onto turbocharger (8).
Use Tooling (A) to lubricate the Allen head bolt for V-band clamp (2). Position V-band clamp (2) onto elbow (1).
Position elbow (1) onto turbocharger (3) and turbocharger (8).
Tighten V-band clamp (2) and V-band clamp (9) finger tight. Ensure that the V-band clamps are seated correctly onto the turbochargers.
Tighten the Allen head bolt for V-band clamp (2) and Allen head bolt for V-band clamp (9) to a torque of 12 N m (106 lb in).
Connect the air inlet hose to the turbocharger and tighten the hose clamp securely.End By:
