Loosen the fuel inlet to the pump and repeat the
procedure until fuel free of air bubbles is discharged.
Tighten the fuel inlet.
Push the primer plunger down and turn the cap clockwise
to secure it in the normal operating position.
Loosen the injector pipe connections, see Figure 40,
and crank the engine with the stop control in and the
throttle wide open until air-free fuel is discharged from
the connections. Tighten each connection in turn while
the engine is still turning.
Wipe the fuel bowls and other areas dry. Start the engine
and check to ensure that there are no fuel leaks.
LUBRICATION AND MAINTENANCE
Using clean fuel, wash out the filter bowl. Install a new
filter element and gaskets and re-install the bowl.
Open the fuel shut-off valve and bleed the system as
described in Operation 44.
EVERY 900 HOURS carry out the preceding
checks plus the following check :
Operation 43 - Fuel Filter (secondary)
Close the fuel tank shut-off valve, Figure 37, by turning
in a clockwise direction.
Clean the filter assembly with a clean, lint-free cloth.
Unscrew the central retaining bolt, Figure 38, and
remove the secondary filter element and bowl. Discard
the filter element.
NOTE : Only the secondary element (rear of engine)
should be changed at this service. (The primary element
should be changed at the 600 hour service). The service
change interval for both elements coincides every 1800
hours e.g. 1800, 3600, 5400 hours etc. However do not
change both the filters simultaneously. It is desirable to
provide a 25-50 hour gap between the change of filters.
It may be desirable, in some locations, to replace the
filters more frequently if fuel contamination is a problem.
Using clean fuel, wash out filter bowl. Install a new filter
element and gaskets and re-install the bowl.
Open the fuel shut-off valve and bleed the system as
described in Operation 44.
EVERY 1200 HOURS or 12 MONTHS
(whichever occurs first) carry out the
preceding checks plus the following :
Operation 44 – 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
of air bubbles flows out, tighten the banjo fitting.
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. Loosen
the bleed screw on the primary filter and move the
plunger up and down until fuel free of air bubbles is
discharged from the bleed screw hole. Tighten the bleed
screw.
Repeat the procedure on the secondary filter, then
tighten the bleed screw.
