Checking turbocharger
This check should be left to authorized service
personnel.
However, a cursory check of the turbocharger may
be carried out as follows:
1. Remove the air cleaner (ACL).
2. Warning! Check that the turbocharger’s
compressor wheel is stationary before
checking.
3. Check whether the rotor shaft is running stiffly or
whether the turbine wheel or compressor wheel
is catching on its housing. Turn the rotor, first
with a light pressure and then with the application
of a light axial load.
If the rotor is difficult to turn, the turbocharger
must be replaced or reconditioned as soon as
possible.
Note: If the turbocharger unit is to function satisfac-
torily, it is vital that the engine’s lubrication system be
maintained according to the maintenance schedule
and that the correct type of lubricating oil be used in
the engine.
Checking valve clearance
This check should be left to authorized service
personnel.
NOTE! The clearance must never be checked
with the engine running – the engine must be
stopped – cold or at operating temperature.
