(a) Check that there is continuity between terminal and ground
with the engine stopped.
(b) Check that there is no continuity between terminal and
ground with the engine running.
HINT: Oil pressure should be over 29 kPa (0.3 kgf/ cm
2, 4.3
psi)
If operation is not as specified, replace the switch.
2. INSPECT WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.

switch in each position.
(b) Heat the switch to above 60°C (140°F) in an oil bath.
(c) Check that there is continuity between terminals with the
switch ON (float up).
(d) Check that there is no continuity between terminals with the
switch OFF (float down).
If operation is not as specified, replace the switch.
2. INSPECT WARNING LIGHT
(a) Disconnect the connector from the switch.
(b) Ground terminal 1 on the wire harness connector.
(c) Turn the ignition switch ON. Check that the warning light
lights up approximately 40 seconds later.

CLUTCH PARTS INSPECTION AND
REPAIR
1. INSPECT CLUTCH DISC FOR WEAR OR DAMAGE
Using calipers, measure the rivet head depth.
Minimum rivet depth:
0.3 mm (0.012 in.)
If a problem is found, replace the clutch disc.
2. INSPECT CLUTCH DISC RUNOUT
Using a dial indicator, check the disc runout.
Maximum runout:
0.8 mm (0.031 in.)
If runout is excessive, replace the clutch disc.
3. INSPECT FLYWHEEL RUNOUT
Using a dial indicator, check the flywheel runout.
Maximum runout:

COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant up to the
ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not remove
the radiator cap while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale
around the radiator cap or radiator filler hole, and the coolant
should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap. EG±330

(b) Check that the fluid coupling is not damaged and that no
silicon oil leaks.
If necessary, replace the fluid coupling.
(c) Reinstall the fan to the fluid coupling with the 4 nuts.
