Follow the procedure for bellows installation and tightening procedures. Tighten the V-band clamps on the turbine housing prior to the bellows V-band clamp to prevent any dragging or binding of the turbocharger rotating components. Contact may cause rapid wear and shorten turbocharger life.
Ensure turbocharger (13) is aligned with dowel (X) and oil drain fitting (Y). Use Tooling (A) and a suitable lifting device to install turbocharger (13). The weight of turbocharger (13) is approximately 136 kg (300 lb).
Install bolts (14). Tighten bolts (14) to a torque of 240 40 N m (177 30 lb ft).
Do not tighten V-band clamp (16) or V-band clamp (15) at this time.

Apply Tooling (B) onto the stud of V-band clamp (16) and V-band clamp (15). Tighten V-band clamp (16) and V-band clamp (15) to a torque of 28 2 N m (248 18 lb in). Loosen V-band clamp (16) and V-band clamp (15) by two to three turns. Tap lightly with a suitable hammer around the diameter of V-band clamp (16) and V-band clamp (15). Tighten V-band clamp (16) and V-band clamp (15) to a final torque of 26 to 30 N m (19 to 22 lb ft).
Tighten clamps (11), clamps (9), and clamps (7) to a torque of 7.5 1.0 N m (66.4 8.9 lb in).
Ensure that the compressor wheel spins freely without binding or dragging. Contact with the housing may cause rapid wear and shorten turbocharger life.
