c. Install "M" type ring by first placing the
expander in the ring groove with the free
ends toward you. Push the ends of the
expander to the inside of the ring groove,
butting the ends together. Make sure the
ends of the expander do not overlap.
Do not clip or cut the ends of the expander or the tension
will be destroyed.
d. Thread one of the two steel rails over the
expander and into the bottom side of the
ring groove. This rail will hold the expand-
er in position. Thread the second steel rail
around the expander and into the remaining
clearance at the top of the ring groove. Be
certain ends of the expander are butted to-
gether and are not overlapping. End gap
for rails should be 1800 apart.
e. Install "B" type compression rings into its
groove(s). Each ring is identified, usually
with a word "top", the "T", a dash, a dot,
or a paint mark. Mark must face top of
