Failure to follow established procedures can lead to damage of the parts.To avoid damage to the parts, always identify and mark the parts so that the parts can be installed in the same location.
The ends of the bellows are very sharp. Injury could occur if the bellows are not handled properly. Handle the bellows by the convolutions.
Note: Refer to Special Instruction, REHS1728, "Application Guideline for the Bellows" for additional information on handling the bellows if the machine is equipped.
Remove both clamp assemblies (5). Remove bellows (6) and position exhaust tube assemblies (4) and (7) aside. Discard clamp assemblies (5) and bellows (6) .

Attach a suitable lifting device to turbocharger (20). The weight of turbocharger (20) is approximately 54 kg (120 lb). Remove nuts (21) and turbocharger (20). Discard nuts (21) .Installation Procedure
The alignment of the bellows is important. Improper alignment may lead to premature failure of the bellows. Misalignment can be identified by visually inspecting the convolutions for uniformity of compression.Inspect the bellows for damage prior to installation. If there is any damage to the convolutions, discard the bellows. Minor damage to the ends of the bellows may be repaired. However, if there is any difficulty in installation after the repair, discard the bellows.
Install turbocharger (20) in the reverse order of removal.
Apply Tooling (A) to the threads of the studs and to the threads of new nuts (21). Tighten nuts (21) to a torque of 70 5 N m (52 4 lb ft).
Install new clamp assemblies (16). Tighten clamp assemblies (16) to a torque of 20 1 N m (177 9 lb in).
Install new clamp assemblies (12) and bellows (13). Tighten clamp assemblies (12) to a torque of 35 2 N m (26 1 lb ft).
Install new clamp assemblies (8) and (10). Tighten the clamp assemblies to a torque of 20 1 N m (177 9 lb in).
