Condition Possible cause and testing Corrective action
4. Noisy
clutchExamine whether the noise is generated when the clutch is disengaged, engaged, or partially engaged.
(a) Broken, worn or unlubricated release bearing Replace release bearing.
(b) Insufficient lubrication of pilot bearing Apply grease.
(c) Loose clutch disc hub Replace clutch disc.
(d) Loose torsion spring retainer Replace clutch disc.
(e) Deteriorated or broken torsion spring Replace clutch disc.
5. Clutch
grabs.When starting the vehicle with the clutch partially engaged, the clutch engages suddenly and the vehicle jumps
instead of making a smooth start.
(a) Grease or oil on facing Replace clutch disc.
(b) Deteriorated cushioning spring Replace clutch disc.
(c) Worn or rusted spline of clutch disc or mainTake off rust, apply grease or replace clutch shaft disc or
mainshaft.
(d) Deteriorated or broken torsion spring Replace clutch disc.
(e) Loose engine mounting Retighten or replace mounting.
(f ) Deteriorated diaphragm spring Replace.

A: RECOMMENDED AIR BLEEDING AND
POWER STEERING FLUID
Recommended power steering fluid Manufacturer
ATF DEXRON II or ATF DEXRON IIEB.P.

CASTROL
MOBIL
SHELL
TEXACO
1) Feed the specified fluid with its level being about 5 cm
(2.0 in) lower than the mouth of tank.
2) Continue to turn steering wheel slowly from lock to lock
until bubbles stop appearing in the tank while keeping the
fluid at that level.
3) In case air is absorbed to deliver bubbles into piping
because the fluid level is lower, leave it about half an hour
and then do the step 2) all over again.
4) Start, and idle the engine.
5) Continue to turn steering wheel slowly from lock to lock
again until bubbles stop appearing in the tank while keep-
ing the fluid at that level.
It is normal that bubbles stop appearing after three times
turning of steering wheel.
6) In case bubbles do not stop appearing in the tank, leave
it about half an hour and then do the step 5) all over again.
7) Stop the engine, and take out safety stands after jack-
ing up vehicle again.
Then lower the vehicle, and idle the engine.
8) Continue to turn steering wheel from lock to lock until
bubbles stop appearing and change of the fluid level is
within 3 mm (0.12 in).
9) In case the following happens, leave it about half an
hour and then do step 8) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the fluid.
(3) Grinding noise is generated from oil pump.
10) Check the fluid leakage at flare nuts after turning
steering wheel from lock to lock with engine running.
CAUTION:

Before checking, wipe off any fluid on flare nuts and
piping.

In case the fluid leaks from flare nut, it is caused by
dust (or the like) and/or damage between flare and
tapered seat in piping.

So remove the flare nut, tighten again it to the speci-
fied torque after cleaning flare and tapered seat. If flare
or tapered seat is damaged, replace it with a new one.
11) Inspect fluid level on flat and level surface with engine
“OFF”by indicator of filler cap.
