Removing pump housing from volute housing
NOTE: Early versions used socket head cap screws. Later versions switched to hex head bolts.
1.
Using a 10 mm hex key or 19 mm wrench as appropriate, remove the eight M12 x 45 mm fasteners holding the
pump housing to the volute housing, Figure 1.
NOTE: The O-ring inside the suction elbow will resist separation of the pump chamber and volute housing.
2.
To break the seal between the pump chamber and volute housing, insert a prying tool between the pump chamber
and volute housing and pry until the seal releases, Figure 2. Alternately, a rubber mallet striking the elbow cup will
help separate the two pieces.
3.
Stand pump up vertically and Lift the pump chamber off to expose the volute housing, Figure 2.
