Preventive maintenance on the turbocharger
The turbocharger may be damaged and, in the worst case, may
break down if the engine is not properly serviced.
1. Check that the engine air inlet system is in good condition,
i.e. that the air cleaner is clean, that none of the hoses are
worn and that hose connections are not defective, which
would allow oil to seep past the seals on the compressor side
and be entrained by the inlet air. The latter may lead to high
exhaust gas temperatures and overheating of the turbine
shaft bear-ing. If corrective action is then not taken, the tur-
bocharger may break down.
2. Change the lubricating oil and filter at the specified intervals.
Check at regular intervals that the lubricating oil lines to the
turbocharger are in good condition and do not leak. Also
check regularly that the oil pressure is not too low, since this
could quickly lead to damage to the turbocharger.
3. Ensure that the fuel system is serviced at the specified inter-
vals. Inadequate fuel supply caused by clogged fuel filters or
incorrect setting of the injection pump reduces the turbo-
charger speed which, in turn, results in a lower engine out-
put.
4. Check that there are no restrictions in the crankcase ventila-
tion. If the vent is blocked, pressure may build up and may
force oil into the inlet air system of the turbocharger and
engine.
WARNING!
Never run the engine with the air inlet
or exhaust pipes disconnected from
the turbocharger, since personnel
could then substain injuries.
IMPORTANT!
Adjustments on the injection pump are
to be performed by authorized person-
nel only.
