Extract the three securing bolts and remove the starter
motor.
Examine the starter pinion for clutch dust contamination
and, if necessary clean with a solution of 75% paraffin
(kerosene), and 25% lubricating oil, This mixture will
provide sufficient lubricating for the pinion until next 600
hours service.
NOTE : This operation should be carried out more
frequently if the clutch is subject to heavy usage.
Clock the fuel tank shut-offvalve, by turning in a clock
wise direction.
Clean the filter assembly with a clean, lint-free cloth.
Un screw the central retaining bolt and remove the
primary filter element and bowl. Discard the filter
element.
NOTE : Only the primary element (front of engine)
should be changed at this service. It may be desirable,
in some locations, to replace the filters more frequently if
fuel contamination is a problem.
EVERY 900 HOURS carry out the preceding checks
plus the following check:
EVERY 1200 HOURS or 12 MONTHS
(Whichever occurs first) carry out the preceding
checks plus the following:
Operation 34 – Bleeding the Fuel System
Loosen the banjo fitting on the fuel inlet pipe to the
injection pump and allow fuel to escape. When fuel free

The injection pump has a built-in hand primer in the form
of a plunger. The plunger is normally screwed down. To
operate the primer, unscrew the primer cap.
