GENERAL MAINTENANCE (to be
performed as and when required)
OPERATION 36
BLEEDING THE FUEL INJECTION SYSTEM
To Bleed the Fuel System
It may be necessary after carrying out maintenance
work on the fuel injection system 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. Unscrew the primer pump knob and proceed to
pump until a high resistance is felt when pushing
the pump downwards.
3. Slowly push the plunger down against the
resistance until the pump knob can be screwed
fully home into the filter head.
The fuel injectors and fuel injection pump are of the
self bleed type and therefore any air remaining in the
system will be purged as the engine is cranked to
start.
