Bleeding the injector lines
Bleed the injector lines if:
• The tractor has run out of fuel.
• New injectors have been installed.
• The injection pump has been removed for service
repairs.
To bleed the injector lines:
1. Loosen the injector line fittings (3) at the injectors, one
at a time.
2. Move the hand throttle control lever to its wide open
position.
3. Crank the engine until air-free fuel flows from each con-
nection, then tighten the fittings to 24 - 29 N·m (18 -
21 lb ft).
NOTICE: If air is not purged from the system, repeat the
above procedures. Do not crank the engine continuously
for more than 30 seconds as this may cause starting motor
failure.
