piping from pump casing. Motor and impeller assembly is removed from back of casing.

1.Drain pump before disassembling Unscrew pipe plug (Ref. No. 14) to drain most of liquid; some will be left in bottom.

2.Unthread fasteners (Ref. No. 5) and remove pump casing (Ref. No. 13) and casing seal (Ref. No. 8) from casing cover (Ref. No. 7).

3.To unscrew impeller (Ref. No. 12), turn counterclockwise (CCW) facing impeller.

NOTE: A screwdriver slot or two flats for use with an open end 7/16" wrench, are provided at rear of motor shaft (remove bearing cap for access). To hold motor shaft from turning, either insert a large screwdriver blade into slot, or use a 7/16" wrench across flats.

4.Unthread fasteners (Ref. No. 6) and remove motor adapter (Ref. No. 4). Seal head and impeller shims (Ref.

No. 11) will come loose at this time.

7.Carefully wipe polished surface of new seal seat with a clean cloth.

8.Wet outside of rubber portion of seal seat with a light coating of soapy water.

9.Press new seal seat squarely into cavity in casing cover. If seal seat does not press squarely into cavity, it can be adjusted into place by pushing on it carefully with a piece of pipe or dowel. Always use a piece of cardboard between pipe and seal seat to avoid scratching seal seat. (This is a lapped surface and must be handled very carefully.)
