ment spacer set includes the inner spacer and outer
spacer.
IMPORTANT: If new bearings are installed into a
used spindle housing, it may not be necessary to re-
place the original large snap ring. If the original
snap ring is in good condition with no evidence of
damage (e.g. spun bearing), leave the snap ring in
the housing and discard the snap ring that comes
with the new bearings. If the large snap ring is found
to be damaged, replace the snap ring. Replacement
bearings are sold only with a matched spacer ring
and large snap ring (Fig. 5). These parts cannot be
purchased separately.
