ADJUSTMENT

LOW AND HIGH IDLE SPEED

Adjust

The high idle speed (cold start idle) is
automatically set by the setting of the low idle
speed and can not be adjusted individually.

1. Check and adjust throttle cable.
2. Start engine and run it until normal operating

temperature is reached.

3. Using a suitable tachometer, check the engine

idle speed.

See ENGINE TUNING DATA,

Information, 300 Tdi Engine

4. If adjustment is necessary, loosen the locknut on

the injector pump.

5. Turn the adjustment screw either clockwise to

increase the engine speed or anti-clockwise to
decrease the speed. Run the engine at an
increased speed for a few seconds then check
the idle speed again.

6. When the correct speed has been achieved,

hold the adjuster screw steady while tightening
the locknut.

NOTE: The low idle speed control is the
only permitted adjustment in service. Any
additional adjustments required must be

entrusted to authorised Bosch agents.

CHECK TURBOCHARGER BOOST PRESSURE

For boost pressure.

See ENGINE TUNING DATA,

Information, 300 Tdi Engine

1. Disconnect, from turbocharger, hose to actuator.

Insert into a suitable "T" piece.

2. Connect a short length of suitable hose to

turbocharger and connect other end to "T" piece.

3. Connect a further length of hose to third leg of

the "T" piece and other end to a pressure gauge
capable of reading in excess of 61 cm Hg. The
pressure gauge hose must be capable of
reaching passenger compartment so that gauge
may be observed.

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.
