Note: Draining oil is not required to disassemble, inspect or replace

the impeller. However, if further disassembly and testing is

required, drain oil.

1. Prior to working on the pump, all electrical power supply circuits

must be disconnected.

2. With pump on its side, remove four bolts (ae) and four washers (ad)

and strainer (ac).

3. Remove retainer plate (ab) and volute (aa).

4. While keeping the impeller (am) from rotating, remove acorn nut

(ap), hex nut (ao) and washer (an).

Note: Impeller vanes may be very sharp due to excessive wear.

Handle with care.

5. Remove impeller (am).

6. Remove key (bi) from rotor shaft for inspection.

6.5.3.2 Impeller Inspection
