REPAIR INSTRUCTIONS, PART 1
2. Resurface the flywheel as required. To
ensure satisfactory service life, the
maximum amount of material that may be
removed from the flywheel surface is
0.070 inch (1.78 mm).
When resurfacing a flat-style flywheel, it is very
important that the machine shop NOT leave a
step on the friction face outer diameter adjacent
to the clutch locating pilot. There is an undercut
relief in the corner between the friction face and
the clutch locating pilot, and resurfacing must go
up to this relief. If resurfacing is done to a depth
which would eliminate the relief, a new relief must
be cut. Refer to Figure 225.
When attempting to resurface as close to the
clutch locating pilot as possible, keep in mind that
the pilot must not be altered. The pilot controls
the location of the clutch. If the locating pilot is
altered, an imbalance will result.
Some machine shop operations may not have the
tooling and locating equipment necessary for
resurfacing a flat-style flywheel.
