1. Remove
air from the fuel filter through the filter vent
plug, (Fig. N19). If a filter vent plug is not fitted, the
return to tank banjo connection in the top of the
filter can be loosened to reduce the time needed to
fill the filter with fuel.
2. Operate the fuel feed pump priming lever (Fig. N20)
or (Fig. N21) until fuel oil free from air bubbles
issues from around the threads. Tighten the plug or
connection.
3. Set the accelerator to the fully open position and
ensure that the stop control is in the 'run' position. If
an electric stop control solenoid is used, turn the
start switch key to the 'R' position.
4. Loosen the vent screw in the hydraulic head lock-
ing bolt (8, Fig. N18) or (Fig. N22) and then the
governor housing vent screw (5, Fig. N18), (3, Fig.
N18A) or (Fig. N23).
5. Operate the fuel feed pump priming lever until fuel
oil free from air bubbles issues from the vent
screws,
6. Tighten first the hydraulic head vent screw and then
the governor housing vent screw.
Note: The
D.P.S. pump has only one vent screw
which is on top of the governor housing |Fg. N24),
7. If a
Thermostart cold start aid is fitted and the fuel
pipe drained, loosen the union nut at the starting aid
and operate the fuel feed pump priming lever until
fuel Oil free from air bubbles issues from the connection.
Tighten the union nut.
8. Loosen
the unions at the atomiser end of two of the
high pressure fuel pipes and operate the starter
motor until fuel oil free from air bubbles issues from
both fuel pipes. Tighten both unions and the engine
is ready to start.
Priming Procedure after changing Earlier
Filter Element
1. With the vent plug on the filter cover removed, and
the union at the filter end of the return pipe (filter to
tank) slackened, operate the feed pump priming
lever until fuel oil, free from air bubbles, issues from
the filter cover vent.
2. Replace the vent plug, and continue to operate the
priming lever until fuel oil, free from air bubbles,
issues from around the threads of the return pipe
union.
3. Tighten the return pipe union.
4. Slacken the union at the filter end of the filter to
injection pump feed pipe, and operate the priming
lever until fuel oil, free from air bubbles, issues from
around the union threads.
5. Tighten the feed pipe union. The pump and filter are
now filled and primed.
Atomisers General
When replacing atomisers in the cylinder head it is
essential that a new, correct type copper washer is fit-
ted betwen the nozzle cap and the cylinder head.
A one piece collar type dust seal is fitted on earlier
engines but later engines have an improved two piece
arrangement which consists of a soft rubber sealing ring
or sleeve
and a rigid plastic spacer which presses down
onto the rubber sealing ring.
