Rework Procedure

Show/hide table

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.

4. Set the drill guide in place for drilling. Drill a hole with a 6.5 mm drill to a max drill depth of 12.5 mm. Drill hole must be centered between the flange halves done on the top side of the flanges.

5. Set 1A-2036 Dowel Pin in place. Note: Pin must be clearance fit, not pressed fit. The dowel should not be over a .5mm maximum protrusion

6. Once the dowel pin is in place, install 372-5858 Clamp following Engine News, SEBD9761, "A New Band Clamp Is Available for Turbochargers on Certain 3500 and C175-16 Engines" for specifications over the flange.
