If the gap on a compres-
sion ring is insufficient,
it may be increased by
filing or stoning the
ends of the ring. File
or stone both ends of the
ring so the cutting action
is from the outer surface
to the inner surface.
This will prevent any
chipping or peeling of
the chrome plate on the
ring. The ends of the
ring must remain square
and the chamfer on the
outer edge must be
approximately .015 inch
(0.038 cm).
(8)
Check the ring side clear-
ance as shown. Refer to
ring side clearances.
