Additional Information
The snowblower woodruff key, part number 7012699, fits into a machined slot on the shaft and engages a matching slot in a pulley or gear. This connection prevents relative rotation between the shaft and mounted component so motion transfers correctly.
If a pulley or gear spins without driving the connected component, drive or auger movement drops while the shaft continues to turn, or parts rotate out of sync during operation, the woodruff key may be worn, sheared, or missing. Loose components on the shaft can also point to key wear or damage.
Disconnect the spark plug wire before beginning the repair. Working with keyed shafts and metal components can expose sharp edges, so work gloves can help protect your hands. Seat the key fully in the shaft slot and confirm the mating component fits flush before reconnecting the spark plug wire.
