4) If the limit is exceeded, re-grind the journals to the undersize
and use the undersize bearing.
Flywheel
Inspect the friction surface – the surface in contact with clutch
disc – for wear and damage. Most of surface flaws, if any, can be
removed by simple machining. A badly damaged flywheel must
be replaced.
Face runout:
Check the flywheel for face runout with a dial gauge, as shown
in figure. Be sure that the runout is less than the limit.
Ring gear tooth wear:
Inspect the teeth for wear and for evidence of crack, chipping or
any other damage. Replace the ring gear if its teeth are found in
bad condition.
Oil seals
Carefully inspect the oil seals removed in disassembly, examining
the lip portion (1) of each oil seal for wear and damage. Use of new
oil seals in reassembly is recommended.
