Other parts used:
Lower Spray Arm (#2)
Upper Spray Arm (#33)
Snap Spray Retainer (#31)

Removed upper and lower washing baskets.

Pulled off Upper Spray Arm (#33). It pulls off easily by hand. No tools required. Replaced with new Upper Spray Arm (#33) and Snap Spray Retainer (#31).

Removed Large Spray Arm Cap(#34,)which has a right hand thread. This allowed me to take the Lower Spray Arm(#2)off.
Removed Filter Guard (#36).

Next I removed the 6 screws from the Pump Cover & Secondary Filter Assembly (#4) with a Torx screwdriver. Removed Lower Spray Arm Seal(#3), Pump House Filter (#6)(which I cleaned), Assembly, Rinse Arm (#7) Jump Up Nozzle (#1). Unscrewed Discharge Housing Nut(#8) by hand. Removed Support, Wash Arm (#9). This allowed me to remove the three screws holding the Discharge Housing Assembly(#11)with a 5/16th nut driver. Next I removed the Impeller Screw (#12) with a 5/16th nut driver. You must hold the Impeller Assembly (#14) firmly while loosening the nut. Removed Impeller Assembly (#12) and Plate, Suction (#15). Cleaned out area of debris,lint, etc. Put back old Plate, Suction (#15) and replaced Impeller Assembly (#14) with new part. Replaced Upper Housing Gasket and Discharge Housing Assembly with new parts. Put back all parts in the reverse order I removed them replacing the O-Ring (#37) with a new part. This O-Ring goes in the Pump Cover & Secondary Filter Assembly (#4).

After completely assembled it ran as good as new!
