IMPELLER SERVICE, MJRL MODELS
Inspection
To prevent accidental starting while servicing, twist and remove all spark plug leads.
Use a 3/16 Ballhex driver to remove the six impeller housing screws. Remove the impeller housing.
Insert a 1/8 in. shim between the impeller and the impeller housing. If the shim moves freely for the entire length of the impeller blade tip on any of the blades, the impeller is worn and must be replaced.
Rotate the impeller 30° and repeat the inspection.
