Step 1

Before beginning repairs, disconnect and remove all hoses.
Flip the motor ignition switch into the OFF position.

Step 2

Use a 13 mm socket to remove the two bolts securing the handle.

Step 4

Use a 13 mm socket to remove the two bolts securing the float chamber housing.

Step 6

Use a 4 mm hex key to remove the bolt securing the engine cover.

Step 8

The impeller is threaded onto the motor's output shaft and will need to be loosened. In order to stop the shaft from rotating, the motor fan assembly will need to be blocked.
Insert a flathead screwdriver between two fan blades on the motor fan assembly.

Step 9

Tap the impeller on one of its blades with a rubber mallet and a punch to break it loose from the threads on the output shaft.

i did this and shattered both the impeller and the fan without it ever loosening. after days of this failing i tried a big crescent wrench which worked instantly. i dont believe hammering is a good idea on a used pump. its not gonna tap right off unless theres no corrosion whatsoever.
