FUEL FILTER: Inspect the fuel filter daily. Drain any
accumulated water from the engine fuel filter/water
separator daily. Change the fuel filter every 400 hours
of operation. Dust and dirt in the fuel system can
cause the injection pump and injection nozzle to wear
quickly. Change the fuel filter as follows:
1. See Figure D.2. Clean the outside surfaces of the
fuel filter assembly. If a drain tap (1) is fitted to the
filter bowl, drain the fuel from the filter.
2. See Figure D.2. Hold the bottom cover of the filter
element and release the setscrew (2) which is fitted
through the filter head above the center of the ele-
ment.
3. See Figure D.2. Lower the bottom cover (3) of the
filter.
4. Remove the element and discard it.
5. Clean the inside surfaces of the filter head and of
the cover.
6. Renew the seals and lightly lubricate them with
clean fuel.
7. Put the bottom cover under the new element and
hold the element squarely to the filter head. Ensure
that the element is fitted in the center against the
joint in the filter head. With the assembly in this
position, engage and tighten the setscrew.
8. Bleed the air from the fuel system. See How to
Eliminate Air from the Fuel System.
