Continued from Part 1.
- Using the small pick or screwdriver, walk the tiny snap ring back into the groove on both the compressor and turbine journal bearings to hold them in place.
- Install the heat shield first, then slide the turbine shaft into the center housing. Gently push downward until you feel a "click"...this means that the turbine seal has been seated into the center housing. DO NOT force the turbine shaft into the housing as you can risk bending the turbine seal and damaging the turbo!
- Install the thrust washer on the shaft
flat side up; use plenty of lube here as well.
- Install the thrust plate.
- Fit the new compressor seal on the compressor seal collar.
- Push the compressor collar downward onto the thrust plate.
- Lower the compressor backplate onto the center housing. A small amount of lube can help assure that the seal does not catch and break on it's way in the backplate.
***Be sure the four backplate bolt holes are aligned with the holes in the center housing.***
- Reinstall the backplate bolts using a small amount of Red Loctite on each one.
- Install the compressor wheel onto the shaft, be sure to put a few drops of Red Loctite on the threads before installing the compressor nut.
- Lower the center housing into the compressor cover keeping the center housing as straight as possible to prevent the compressor wheel from hitting the housing. Reinstall a couple bolts in the compressor cover to hold it in place.
- Reinstall the center housing in the turbine housing. Keep the bolts loose so the housing can rotate to make sure all of the bolts can be tightened.
- Reinstall the wastegate actuator.
Your turbo rebuild is complete. Now go out and boost!!
***Be sure to check back as I'll be posting more rebuild guides for the T25/T28 and Holset turbos!***
