Checking valve clearance
This check should be left to authorized service per-
sonnel.
NOTE! The clearance must never be checked with
the engine running – the engine must be stopped –
cold or at operating temperature.
Checking the Turbocharger (TC)
This check should be left to authorized service per-
sonnel.
However when cleaning/replacing the filter a cursory
check of the turbocharger may be carried out as follows:
1. TAMD163A, TAMD163P: Remove the air cleaner
(ACL) filter housing.
TAMD162C: Remove the air cleaner (ACL)and its
holder.
2. Warning! Check that the turbocharger’s
impeller is stationary before checking.
3. Check if the shaft is stiff or if the turbine or com-
pressor 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 satisfactorily,
it is vital that the engine’s lubrication system be main-
tained according to the maintenance schedule and that
the correct type of lubricating oil be used in the engine.
