DISASSEMBLY AND INSPECTION
1. Remove the screen, volute, and impeller as previously stated
and drain oil from the motor housing.
2. Loosen the gland nut (17) and slide it back on the cord (18).
3. Remove the hex nuts (20) and lock washers (21) from the
studs (26) and pull the housing end (19) from the motor
housing (25).
4. Disconnect the cord set (18) and check for damage or cracks.
Replace if required.
5. Remove the grommet (15) and friction rings (16) from the
housing end (19). Replace if damaged.
