Maintenance and care
31
Turbocharger
At every engine oil change check the oil pipes for leaks and constrictions.
Furthermore, a regular check should be kept on charge air and exhaust gas pipes.
Any leakages should be attended to at once because they are liable to cause over-
heating of the engine.
Starter motor
Check that the electric cables are properly fastened and that contacts and plug con-
nections are secure.
In engines fitted with electronic speed pickups at the gear ring (electronic speed gov-
ernor), the speed pickup are to be cleaned too and metal chips that may adhere are to
be removed.
Note:
Always disconnect the battery earth cable before starting work on the electrical sys-
tem. Connect up the earth cable last, as there is otherwise a risk of short-circuits.
Temporary decommissioning of engines
Temporary anti-corrosion protection according to MAN works norm M 3069 is required for
engines which are to be put out of service for fairly long periods.
The works norm can be obtained from our After-Sales Service department Nuremberg
works.
