Rebuilding the turbo
Mark the compressor wheel and turbine wheel so they can be lined back up when reassembled. (The turbine
wheel and shaft are one single piece)
A 5/8" socket should fit the turbine wheel "nut". If it does not fit, CAREFULLY secure the wheel by this
nut in a vice.
Remove compressor nut using 12 point 7/16" socket then remove compressor wheel.
Remove turbine wheel and shaft from center section-- you may have to tap the end of the shaft to get it
out. You should now have the turbo broken down into four pieces:
(a) the compress wheel and nut;
(b) the center section;
(c)the heat shield (also called the dog dish);
(d) the turbine wheel and shaft.
Next, remove the compressor seal plate by removing the 10mm bolts securing it to the bearing housing. Removing
the seal plate will expose the following parts:
(a) the compressor seal;
(b) the thrust collar;
(c) the thrust bearing;
(d) the thrust bearing
(e) 'O' ring
