Fuel System Air Removal
AIR MUST BE REMOVED FROM THE FUEL SYSTEM.
AIR CAN ENTER THE FUEL SYSTEM WHEN:
1. An engine stopped from lack of fuel.
2. The fuel filter
has been replaced or the filter cup has been cleaned
.
3. Any connections between the
injection pump and fuel tank have been
loosened or disconnected for any reason.
4. The
tractor has not been operated for an extended period of time.
5. The
fuel pump has not operated correctly.
NOTE: If the tractor has no fuel, it is possible to put fuel in the tank and
start the engine without doing the air removal procedure, but a small
amount of air can be in the filters. Air in the system will cause loss of
power and stall the engine when a load is applied.
To remove air from the fuel system, turn off the engine and use the
following procedures:
Loosen the No. 1 air vent screw
on the fuel filter until the fuel
flowing from the fuel filter is free
of air bubbles. Tighten the No. 1
air vent screw.
Loosen the air vent screw on the
injection pump and turn the key
switch “ON” position until the fuel
flowing from the pump is free of
air bubbles. Tighten the air vent
screw.
Loosen the No. 2 air vent screw
until the fuel flowing is free of air
bubbles.
Tighten
the No. 2 air vent screw.
