Checking the Turbocharger (TC)
This check should be left to authorized service
personnel.
However, a quick check of the turbocharger when
cleaning/replacing the air cleaner may be carried out
as follows:
1. Remove air cleaner (ACL).
2. Warning! Check that the turbocharger’s
impeller is stationary before checking.
3. Check if the shaft is stiff or if the turbine or
compressor wheels are touching their housings.
Turn the shaft using light pressure, followed by
pulling it gently in the axial plane.
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 satisfacto-
rily, 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.
