end. Position the O-ring (Item 062.4) into the shaft extension thread relief.
Position Casing Gaskets (Item 060.3) onto Strainer (Item 103), aligning the
holes. To verify the impeller running clearance, compare the depth from the

impeller vanes. The total difference should be 1/32” – 1/16”. Adjust as
necessary by adding or subtracting casing gaskets.
Slide strainer and gaskets into the casing bore. Position the Pump Stand
