IMPORTANT:
・
Be sure to install the O-ring when re-installing the
strainer.
・
When the fuel tank is emptied and air is trapped in the
fuel system, bleed the air as follows:
-
Open the fuel filter cock and loosen the air-
bleeding screw,4. And evacuate trapped air
completely along with fuel out of the stainer cup.
Re-tighten the air-bleeding screw. The air trapped
between the fuel pump and injectors is evacuated
automatically when the starter switch is turned to
the ON position(
O
).
9. FUEL
HOSES
Check the fuel hoses for cracks and fuel leak after every
100 hours of operation. A damaged hose should be
replaced with a new one.
10. FAN BELT
WARNING:
・
Before checking the fan belt, stop the
engine and remove the starter key without
fail.
・
Wait until the engine and accessories cool
down completely to prevent burns.
The fan belt,1, is accessible from the right rear of the
engine room by opening the engine hood. Check the
belt for tension and damage.
Push down the belt with a finger at the intermediate
point between the alternator,2, and crankshaft pulley,3,
with a force of 10 kgf (22 lb) and see its deflection,A. If it
deflects by about 10 mm (0.4 in.), the tension is proper.
When the belt deflection is improper, correct in the
following procedure:
a.
Loosen the lock bolt,4, and adjust bolt,5, of the
alternator.
b.
Pull the alternator outward to apply more tension
to the belt. Tighten the lock bolt and adjust bolt
temporarily while pulling the alternator.
c.
Check for the belt deflection to see if the tension
is proper. If so, tighten the lock bolt and adjust bolt
securely.
IMPORTANT: When the belt is found to be defective,
ask your dealer for replacement.
