Turbocharger - Check
NOTICE: Observe the following recommendations on the adequate lubrication to avoid serious damage to the tur-
bocharger bearing.
The following procedure must be observed in order to
prevent the turbocharger bearings from deteriorating.
1. 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.
2. Remove the air inlet tube from the turbocharger and
spin the compressor wheel by hand to pre-lubricate the
bearings.
3. Reconnect the oil inlet and air inlet tubes but not the oil
outlet.
4. Disconnect the electrical wire to the fuel injection pump
fuel shut-off solenoid.
5. Place a suitable receptacle below the oil outlet port and
crank the engine until oil flows from the outlet port.
6. Reconnect the oil outlet tube using a new gasket and
tighten the retaining bolts to the torque.
7. Reconnect the fuel injection pump fuel shut-off solenoid
wire.
8. Check the engine oil level and, if necessary, top up.
Start the engine and check for oil and air leaks.
9. Observe the oil pressure light. If the oil pressure lamp
does not turn off in the first few seconds of idling, im-
mediately stop the engine and consult your Dealer.
10. On every start-up the engine should be allowed to idle
( 1000 RPM maximum) for 60 s before operating un-
der load, to ensure an adequate oil supply to the tur-
bocharger bearing.
11. 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.
