IMPELLER REMOVAL
READ all safety instructions before servicing unit.
DISCONNECT spark plug wire before servicing unit.
1. Wait for engine to cool and disconnect spark plug.
2. Drain fuel and oil from the engine.
3. Remove engine, impeller and mounting plate by removing bolts around outside of housing.
4. Leaving engine fastened to plate, remove impeller bolt and lock washer and slide impeller off crankshaft. (A puller
may be required). CAUTION: Do not drop impeller.
5. 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.
6. If the impeller cannot be loosened, obtain a 3/8-24 x 2 3/4” longer bolt of the same diameter and thread type as the
impeller bolt. Invert engine and impeller and support engine above ground to prevent recoil damage. Thread longer
bolt by hand into the crankshaft until bolt bottoms. Using a suitable gear or wheel puller against the bolt head and the
impeller back-plate (near the blades), remove impeller from shaft.
7. To reinstall impeller, use a new impeller bolt and lock washer.
8. Tighten impeller bolt. Torque impeller bolt to 33-38 Ft. Lbs. (45-51 N.m).
9. Reinstall engine, impeller, and mounting plate onto housing in reverse order of removal.
10. Before connecting spark plug wire, slowly pull engine starting rope to insure that impeller rotates freely.
11. Reconnect spark plug wire.
