GDS Compressor Upgrade

Remove the compressor housing from the rest of the turbo by removing the large snap ring and pulling the housing straight off.
Using a 3/4' 12pt socket hold the exhaust wheel while removing the shaft nut. The shaft nut is "left-handed (reverse thread)".
Slide the old compressor wheel straight off the shaft.
Remove the exhaust shaft by lightly tapping it with a rubber mallet.
Cover or plug up all holes in the center/ bearing housing so no metal gets inside during machining.
Chuck up the bearing housing in a machining lathe and machine out the pocket. Machine it out to at least 3.420". The depth does not change.

Blow metal shavings off remove plugs or covers.
Reinsert the exhaust wheel and make sure the shaft seats and spins freely in the center/bearing housing.
Slide the new wheel and torque the shaft nut down.
12 point nut = 125 inch lbs.
6 point nut = 135 inch lbs.
Make sure the wheel spins freely before installing the new compressor housing.
Install the new compressor housing and make sure it sits flat before installing the large snap ring. DO NOT INSTALL ANY O-RINGS!!
Install the large snap ring and make sure it sits all the way in.
Make sure the turbo still spins freely and does not drag.
