Service repair no - 19.42.06
1. Disconnect actuator hose from turbocharger and
insert a suitable ’T’ piece connector.
2. Connect a short length of suitable hose to
turbocharger and ’T’piece.
3. Connect further hose to ’T’ piece and pressure
gauge LRT-12-011. The pressure gauge hose
must be long enough to reach into the vehicle
cab so that the gauge can be observed by driver
or passenger.
4. To check maximum boost pressure, drive
vehicle normally, but in such a manner that full
throttle can be maintained whilst climbing a hill
with engine speed held steady between 2,500
and 3,000 rev/min. Under these circumstances
boost pressure should read 0,95 - 1,09 Kgf/cm

(13.5 - 15.5 lb/in

).
PRIMING THE FUEL SYSTEM
Service repair no - 19.50.01
NOTE: If the fuel system has been
completely drained carry out the
procedures for priming both the
sedimentor, if fitted, and fuel filter and injection
pump.
Sedimentor and fuel filter
If the sedimentor or fuel filter have been dismantled
and air has entered the fuel system carry out the
following procedure:
1. Slacken fuel filter bleed screw.
2. Operate hand priming lever on fuel lift pump until
fuel, free from air, emerges from filter.
NOTE: Ensure that the fuel pump lever is
on the bottom of operating cam when
priming, otherwise maximum movement of
the lever cannot be achieved.
3. Tighten filter bleed screw whilst fuel is still
emerging.
