5.7. Turbocharger (for D1146T/PU086T, P086TI)
5.7.1. Maintenance
(by authorized specialist personnel)
The turbochargers do not call for any specific maintenance.
The only points to be observed are the oil pipes which should be checked at every oilchange
for leakage and restrictions.
The air cleaners should be carefully serviced.
Furthermore, a regular check should be kept on charge air exhaust gas pipes. Any leakages
should be attended to at once because they are liable to cause overheating of the engine.
When operating in highly dust or oil-laden atmospheres, cleaning of the air impeller may be
necessary from time to time. To this end, remove compressor casing (Caution , Do not skew
it!) and clean in a non-acid solvent, if necessary using a plastic scraper.
If the air compressor should be badly fouled, it is recommended that the wheel be allowed to
soak in a vessel with solvent and to clean it then with a stiff brush. In doing so, take care to see
that only the compressor wheel is immersed and that the turbocharger is supported on the
bearing casing and not on the wheel.
5.7.2. Special hints
It is recommended that the radial and
axial clearances of the rotor be checked
after every 3,000 hours operation.
This precaution will enable any wear of
the Measuring of axial clearance bear-
ings to be detected in good time before
serious damage is caused to the rotor
and bearings.
