SERVICING THE SM PUMP
Note: Servicing the pump shaft is discussed later in this manual in the
appropriate gearbox/pedestal service sections.
Suction Tube and Front Clearance Ring
See Figure 6-4: “Stainless Max Pump Breakdown” on page 6-9.
1. First, review preceding section “Before You Begin...,” beginning
on page 6-1.
2. With the suction components removed, exposing the clearance
ring (bronze), thread three jacking screws (M10) into the tapped
holes adjacent to the bolt-down holes.
Evenly tighten the jacking screws until the suction cover plate is
free (removable by hand).
