First thing is to remove the large compression C clip that holds the compressor housing on. Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1412.jpg 2. Second is to remove the 4 bolts that hold on two C shaped brackets to the exhaust housing. Once removed heat may need to be applied to help break it loose from the center cartridge. Pay special attention when removing it as it does not get caught up on the turbine blades, best way to do this is to keep spinning the shaft while wiggling it loose.

Next you are left with the center cartridge with wheels and shafts intact. You want to make a mark on the wheel and the shaft, both with a paint pen and a scribe to etch a small mark so it can later be lined up for assembly.

Then use a 12pt open ended wrench to remove the nut from the compressor wheel keep in mind it is left handed threads.

Once the compressor wheel is off you will see a another C clip, remove that Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1421.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1422.jpg 6. Once C clip Is off you will now see the seal plate/deflector, that will come right out Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1423.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1425.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/IMG_8552.jpg 7. Once the seal plate is off you will see the oil deflector then the thrust bearing that just comes right out, there is also a piston ring which holds the shaft in place, remove that and the shaft will then slide out of the housing. A heat shield will also come off which just rests in place right before the turbine blade. Image: http://i625.photobucket.com/albums/tt338/sg622899/IMG_8553.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1436.jpg 8. After the thrust bearing is removed you will see this (not sure on the name) some collar maybe which also comes right out. Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1429.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1430.jpg Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1431.jpg 9. Sequence of parts thus far: Image: http://i625.photobucket.com/albums/tt338/sg622899/GEDC1432.jpg 10. Now you will start to see the journal bearings, the first one which is held into place with a very small C clip, remove the clip and the first journal bearing comes right out.
