scale, the air cleaner element should be replaced. Re­
fer to the proceeding removal/installation para­
graphs.
Resetting t h e Filter Minder: After the air
cleaner (filter) element has been replaced, press the
rubber button on the top of the Filter Minder (Fig.
2). This will allow the yellow colored disc to reset. Af­
ter the button has been pressed, the yellow disc
should spring back to the UP position.
If the Filter Minder gauge has reached the red col­
ored zone, and after an examination of the air
cleaner (filter) element, the element appears to be
clean, the high reading may be due to a temporary
condition such as snow build-up at the air intake.
Temporary high restrictions may also occur if the air
cleaner (filter) element has gotten wet such as during
a heavy rain or snow. If this occurs, allow the ele­
ment to dry out during normal engine operation. Re­
set the rubber button on the top of the Filter Minder
and retest after the element has dried.
REMOVAL/INSTALLATION
(1) Loosen the air inlet tube clamp at air cleaner
housing inlet (Fig. 1). Remove this tube at air cleaner
housing cover.
(2) The housing cover is equipped with four (4)
spring clips (Fig. 1) and is hinged at the front with
plastic tabs. Unlatch the clips from the top of air
cleaner housing and tilt the housing cover up and
forward for cover removal.
(3) Remove the air cleaner element from air
cleaner housing.
(4) Before installing a new air cleaner element,
clean inside of air cleaner housing.
(5) Position air cleaner cover to tabs on front of air
cleaner housing. Latch the four spring clips to seal
cover to housing.
(6) Install the air inlet tube at air cleaner housing
inlet. Note the hose alignment notches at both the in­
let hose and air cleaner cover (Fig. 1).
(7) Position the tube clamp to the inlet tube and
tighten to 3 N-m (25 in. lbs.) torque.
AIR BLEED PROCEDURE
A certain amount of air becomes trapped in the fuel
system when fuel system components are serviced or
replaced. Bleed the system after fuel system service
according to the following procedures.

MANUAL BLEEDING
Some air enters the fuel system when the filters or
injection pump supply line are changed. This small
amount of air is vented automatically from the injec­
tion pump through the fuel drain manifold. This is if
the filter was changed according to instructions.
The system will have to be bleed manually if:
® The fuel filter is not filled before installation
® The fuel injection pump is replaced
• High-pressure fuel line connections are loosened or
lines replaced
• Initial engine start-up or start-up after an ex­
tended period of no engine operation.
(1) Loosen the low-pressure bleed bolt (Fig. 3).
Fig. 3 Low-Pressure Bleed Bolt
(2) Operate the rubber push-button primer on the
fuel transfer pump (Fig. 4). Do this until the fuel ex­
iting the low-pressure bleed bolt is free of air.
If the primer button feels as if it is not pumping,
rotate (crank) the engine approximately 90 degrees.
Continue pumping until air is removed.
(3) Tighten low-pressure bleed screw to 8 N-m (6 ft.
lbs.) torque.
