If the turbine housing must be rotated to remove the turbocharger, loosen the V-band clamp only enough to allow for rotation (typically 7-10 turns). If the V-band clamp is loosened excessively, the housing may contact the turbine wheel and cause damage. Contact with the housing may cause rapid wear and shorten turbocharger life.
Attach Tooling (A) and a suitable lifting device onto turbocharger (6). The weight of turbocharger (6) is approximately 136 kg (300 lb).
Mark the orientation of V-band clamp (7) for installation purposes. If necessary, loosen V-band clamp (7). Remove bolts (8). Remove turbocharger (6).
