IMPELLER REMOVAL
1. Disconnect spark plug wire.

3. Remove the nozzle (item 7) from the housing, then remove the plate it was attached to (item 30).
4. Walk the belt (item 22) off of the lower pulley (item 23) and then slide it off of the impeller groove. If you cannot walk
it off of the bottom pulley loosen the bearings (item 24) on the underside this will allow a little more play in the pulley.

10. Reinstall new impeller, new impeller bolt and lock washer in reverse order of removal. (See the parts drawing on
pages 9-12 for parts break-down and parts list on page 10 for proper impeller bolt torque specifications.)
