15) Remove the mechanical seal from the housing. If only replacing the mechanical seal,
proceed to step 18.
NOTICE! To help prevent water leaks, be careful not to damage
the surfaces of the O-ring or mechanical seal.
5b. Lower Housing
16) Remove the O-ring and the bolts securing the lower housing to the gear motor and
16) Remove the O-ring and the bolts securing the lower housing to the gear motor and
remove the housing from the gear motor. If inspection of the upper bearing inside the
extruding head (see "V.C.1. Upper Bearing Wear Check") indicates that it is out of
tolerance, replace both it and the bearing inside the lower housing.
Note: Replacing the bearing requires a bearing press adaptor. If one is not available,
