Note : Be sure to replace any clutch disc which has
0.2mm(0.008in) or less in rivet suppression.
Use of a insufficient rivet depression disc will
result in serious damage to the flywheel and
the pressure plate.
2) Any oil stained clutch disc must be replace.
However,a very small oil stain may simply be
removed by use of a volatile solvent.
Note : The causes of oil stains must be located and
necessary corrective measures must be taken.
3) Hardened lining surfaces must be repaired by use
of a sandpaper,or be replaced with a new ones.
4) When loose rivets are found,replace the clutch
disc assembly because those of rivets will loosen
again even if they are retightened.
5) Install the disc on the input gear and inspect the
rotational play. If the measurement deviates from
the specified value, replace the disc.
Rotational play of the
hub spline
Usable limit
0.3mm(0.012in)
6) Measure the deviations of the clutch disc.If the
measurements are beyond the usable limits,
replace the clutch disc assembly.(Fig4-6)
Usable limit
Surface deviation 0.5mm(0.019in) or less
Lateral deviation 1.1mm(0.043in) or less
Vertical deviation 1.0mm(0.039in) or less

(4) Inspection of other parts.
Inspect the release levers,return springs,lever
plates,clutch cover assembly, and lever
bolts for wear,damage,and deformation,and
replace parts which exhibit abnormalities.
1.3. REASSEMBLY
Reassemble them in reverse order of disassembly
in accordance with the following instructions.
1) Be sure to keep oil off of the clutch disc,the
pressure plate,and the flywheel.
2) Apply a thin coat of molybdenum disulfide-
based grease to revolving or sliding parts
prior to reassembly.
Note : Be sure not to apply too much grease
because this will cause clutch slippage.
3) When installing the clutch disc on the
flywheel ,turn the longer protrusion of the
hub towards the flywheel.The reverse
installation will damage the clutch cover or
the disc.When installing the clutch assembly,
use a special tool.
