Disassembly

Remove the turbine housing
Remove the V-clamp and the turbine housing (in that
order) from the turbocharger.
IMPORTANT! The compressor cover, bearing
housing and turbine housing must be reassem-
bled in correct orientation. Therefore, put align-
ment marks with a punch or marker.
Remove the compressor cover
1. Put the turbocharger on a workbench with the
compressor cover down. Unscrew the bolts and
remove the lockplates.
2. Lightly tap around the compressor cover with a
soft-faced hammer to remove the cover. Also re-
move the o-ring from the bearing housing.
Remove the compressor wheel
IMPORTANT! Handle the compressor wheel and
turbine wheel with care during disassembly and
assembly. Vanes can easily bend when
dropped or hit.
1. Fasten the flange of the turbine housing in a vise
and install the bearing housing to the turbine
housing with the v-clamp..
2. Hold the boss of the shaft & turbine wheel and re-
move the lock nut holding the compressor wheel.
NOTE! The lock nut has left-handed threads.
3. While holding the turbine wheel with one hand,
turn the compressor wheel lightly with the other
hand and remove.
