shaft seal (28) seats in the hub of the impeller (33). Rotate
impeller to check for binding. Position gasket (36) on volute

(36) on spacer ring and position impeller and motor housing on
spacer ring (31). Position lockwasher (12) on cap screw (26)
and screw into volute (1). Torque to 100 in-lbs. Check for free
