Maintenance of Major Components

5.4.5. Maintenance

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 oil change for

leakage and restrictions.

The air cleaners should be carefully serviced.

Furthermore, a regular check should be kept on charge air and exhaust gas pipes. Any leakage 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 do this, remove compressor casing (Caution : Do not skew it!) and clean in 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.
