• If the surface contacting clutch disc is damaged, or
excessively worn, replace flywheel.
Flywheel Face Runout
Check flywheel face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Flywheel face runout
Limit: 0.2 mm (0.0079 in.)

Honing or Reboring Cylinders
1) When any cylinder needs reboring, all other
cylinders must also be rebored at the same time.
2) Select oversized piston according to amount of
cylinder wear.
Oversize piston specification
Oversize 0.50: 78.453 – 78.468 mm (3.0887 –
3.0893 in.)
3) Using micrometer, measure piston diameter.

4) Rebore and hone cylinder to the following
dimension.
NOTE
Before reboring, install all main bearing caps
in place and tighten to specification to avoid
distortion of bearing bores.
Cylinder bore diameter to be rebored
Oversize 0.50: 78.500 – 78.514 mm (3.0906 –
3.0911 in.)
5) Measure piston clearance after honing.
Piston clearance
0.032 – 0.061 mm (0.0013 – 0.0024 in.)
