OPERATION 36
BLEEDING THE FUEL INJECTION SYSTEM
It may be necessary after injection pump removal,
replacement of injector high pressure lines or after
running out of fuel, to purge the system of air to allow
the engine to start.
If the engine fails to start after several turns, after one
of the above situations has occurred, bleed the
system using the following procedure:
1. Ensure the tractor has adequate fuel and the
battery is fully charged.
2. Bleed the fuel system as described in Operation
26.
3. 'Crack' open the nuts (1) on the high pressure
lines to each of the injectors. With the aid of an
assistant, crank the engine on the starter motor
to expel the air. Tighten the injector nuts as the
engine begins to fire.
OPERATION 37
CHECK BRAKE PEDAL
LATCHING/UNLATCHING
The hydraulically actuated brakes require no
adjustment. However, if any part of the brake pedal
linkage or the master cylinder assembly is replaced
or if the pedal latch will not readily engage the hole
in the right--hand pedal shank, adjust the pedal as
follows:
Adjust the clevis by loosening the locknut . The
distance from the bulkhead to the centre of the clevis
hole should be 137mm (5.4 in.). Adjust both pedals
and ensure pedal latch engages properly.
