IMPELLER REMOVAL
1. Disconnect spark plug wire.
2. Secure the unit to keep it from moving.
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.
5. Slide belt out of belt groove in impeller hub drive pulley.
6. Remove impeller bolt and lock washer.
7. If impeller slides off freely, proceed to (step 12). (Do not drop impeller).
8. If impeller does not slide off crankshaft, place two crowbars between impeller and housing on opposite sides. Pry
impeller away from engine until it loosens. Using a penetrating oil can help loosen a stuck impeller.
9. Slide impeller off of crank shaft and remove impeller from housing.
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.)
11. When impeller is installed, slide the belt back into the groove on the hub and walk it back onto the bottom pulley.
Retighten the bearings if they were loosened.
12. Reattach nozzle plate and nozzle in reverse order of removal.
13. Reconnect spark plug wire.
14. Check for proper operation.
Grease: Wheels, Casters, and Shaft Bearings.
