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 al-
low 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
bearing. If corrective action is then not taken, the turbo-
charger 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 turbocharg-
er speed which, in turn, results in a lower engine output.
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.
Maintenance of the exhaust gas cleaner
The exhaust-gas cleaner of a well maintained engine needs hard-
ly any maintenance. Yet, an iterative check-up for carbonization
ought to be made, appr. twice a year. If necessary dismount and
clean the exhaust-gas cleaner as follows:
1. Loosen the tube clamps and remove the cleaner.
2. Dry-brush the cleaner on the intake-side.
3. Clean with pressured air from the exhaust-side.
4. Soak the cleaner in soap-water for, at least, one hour.
5. Clean with pressured air from the exhaust-side.
6. Clean with high-pressured water (0.3 MPa max.) from the ex-
haust side.
7. Dry with pressured air.
WARNING!
Never run the engine with the air inlet
or exhaust pipes disconnected from
the turbocharger, since personnel
could then sustain injuries.
IMPORTANT!
Adjustments on the injection pump are
to be performed by authorized person-
nel only.
