Rework Procedure
1. Prior to changing out the clamps, loosen the two bellows that connect to the turbine housing so that the turbo is isolated and there is no force pulling on the turbine housing (Image 1.1.1). Check that the turbo housing is aligned properly; make sure the two mating flanges are flush all the way around. Note: It may be necessary to loosen the turbo cartridge bolts to allow the cartridge to move and align the cartridge flange with the turbo flange.

2. Retain the housing while the clamp is off and drill; using c-clamp to hold in place.

3. Install an old v-band clamp to be modified for use as a drill guide. Fabricate the drill guide using an old v-band clamp and weld a lead boss to the old v-band clamp. Ensure this boss is centered on the old v-band clamp.
