47PERIODIC SERVICE
BCleaning Fuel Filter
This job should not be done in the field, but in a clean
place.
1. Loosen and remove the filter bowl, and rinse the inside
with kerosene.
2. Take out the element and dip it in the kerosene to
rinse.
3. After cleaning, reassemble the fuel filter, keeping out
dust and dirt.
4. Bleed the fuel system.
(See "SERVICE AS REQUIRED" in "PERIODIC
SERVICE" section.)
A When the fuel filter bowl has been removed, fuel stops
flowing from the fuel tank. If the fuel tank is almost full,
however, the fuel will flow back from the fuel return
pipe to the fuel filter. Before checking, make sure the
fuel tank is less than half-full.
A If dust, dirt or water enters the fuel system, the fuel
pump and injection nozzles are subject to premature
wear. To prevent this, be sure to clean the fuel filter
bowl and element periodically.
BAdjusting Fan Belt Tension
To avoid personal injury:
A Be sure to stop the engine before checking belt
tension.
1. Stop the engine and remove the key.
2. Apply moderate thumb pressure to belt between
pulleys.
3. If tension is incorrect, loosen the alternator mounting
bolts and, using a lever placed between the alternator
and the engine block, pull the alternator out until the
deflection of the belt falls within acceptable limits.
4. Replace fan belt if it is damaged.
