24. SERVICE PROCEDURE
When the air inlet hose is removed, the turbocharger
can be damaged by entry
of any foreign material during engine operation. When service work is com-
pleted, remove shield and store for future use. Reinstall air intake hose with
hose clamp.
As a precaution against dirt getting into the engine, frequently inspect the flexible
rubber hose connections
clamped to the turbocharger
compressor
housing. If
signs of deterioration are evident, replace immediately. To eliminate undue strain
on the rubber hose connections,
insure that pipes are properly aligned.
All the joints between the air cleaner and the turbocharger
and between the
turbocharger
and the cylinder heads must be tight. All the gaskets must be in
good condition and the bolts must be drawn up tight.

PRIMING
The turbocharger must be primed when the engine has been idle for more than
30 days or more. Prime the turbocharger
as follows:
Be sure the hydraulic lock lever is applied. Disconnect the lead to the engine
fuel shut off solenoid. Turn the ignition switch to the START position. Crank
the engine until oil pressure is indicated by the engine oil pressure monitor on
the control console. This should provide and adequate
amount of oil to
lubricate the turbocharger. Cranking the engine must be limited to 30 second
periods with two minute between periods.
