Turbocharger - Check

TURBOCHARGER
Serious damage to the turbocharger bearing can result
from inadequate lubrication if the following recommenda-
tions are not observed.
The following procedure must be observed in order to pre-
vent the turbocharger bearings from deteriorating.
Disconnect the inlet and outlet oil pipes from the tur-
bocharger and pour some clean engine oil into the oil
inlet port, taking care that no contaminants enter the
turbocharger.
Remove the air inlet tube from the turbocharger and spin
the compressor wheel by hand to pre-lubricate the bear-
ings.
Re-connect the oil inlet and air inlet tubes but not the oil
outlet.
Disconnect the electrical wire to the fuel injection pump fuel
shut-off solenoid.
Place a suitable receptacle below the oil outlet port and
crank the engine until oil flows from the outlet port.
Re-connect the oil outlet tube using a new gasket and
tighten the retaining bolts to the torque.
Re-connect the fuel injection pump fuel shut-off solenoid
wire.
Check the engine oil level and, if necessary, top up. Start
the engine and check for oil and air leaks.
Observe the oil pressure light. If the oil pressure lamp does
not turn off in the first few seconds of idling, immediately
stop the engine and consult your Dealer.
On every start-up the engine should be allowed to idle (
1000 RPM maximum) for 60 s before operating under load,
to ensure an adequate oil supply to the turbocharger bear-
ing.
The engine should also be allowed to idle without load for
two minutes before shut-down to enable the oil to dissipate
the heat from the turbocharger bearing.
