Turbocharger inspection

WARNING! Check the turbocharger only when
the engine is cool and the compressor wheel is
not running.
Check shaft play, take a hold of the compressor
wheel nut and turn the wheel to feel rattle and listen
for abnormal noise. Replace the bearings if the wheel
is noisy or rattles.
NOTE! Also check the turbocharger when the exhaust
color is abnormal.
Regular cleaning of the compressor housing and com-
pressor wheel is recommended for daily operation in
dusty or oil saturated air. Heavily fouled compressor
parts can result in low boost pressure. The compres-
sor part can be cleaned with the unit dismantled as
follows:
1. Dismantle the compressor housing.
2. Clean the compressor housing, compressor wheel
and the end-head in paraffin or the equivalent.
3. Fit the compressor housing.
