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 (25) in the reverse order of removal.
Apply Tooling (A) to the threads of the studs and to the threads of new nuts (26). Tighten new nuts (26) to a torque of 70 5 N m (52
