SECTION 3 – LUBRICATION AND MAINTENANCE
3-10
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 ① at the
injectors.
2. Move the hand throttle control lever to its
wide open position.
3. Crank the engine until air-free fuel flows from
each connection, then tighten the fittings to
24-29 N·m.
IMPORTANT: 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
starter motor failure.
AIR CLEANER
The air cleaner ① is accessed by opening the
tractor hood.
The air cleaner assembly contains two elements:
an outer (primary) element, and an inner (safety)
element.
To remove the primary element, loosen the
spring clamps ② and remove the end cap from
the air cleaner body to expose the primary
element ③.
