Assembly (Fig. 25)
Important: If new bearings will be installed into a
used spindle housing that has the original large
snap ring installed, discard the large snap ring that
comes with the new bearing set because it is not
necessary to replace the original large snap ring in
the spindle housing. However, new bearings with
their matched spacer set, spacer ring and large
snapringmust always beinstalled when thespindle
housing is being replaced.
