7. If the gap on a compression
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.0015
inch (.038 cm).
8. Check the ring side clear-
ance as shown. Refer to
ring side clearances.
