V-BELT TENSION CHECKNlSFliAl
1.Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE, If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage,
of the
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.
