Additional information

This woodruff key, part number 714-0135, fits into the curved keyway on the shaft to lock pulleys, gears, or other driven components in place. Proper seating helps ensure reliable torque transfer and prevents slippage during operation.

If a driven component spins freely on the shaft, chatters under load, or fails to move even though the shaft turns, the woodruff key may be sheared, worn, or missing. Deformation or improper fit can also prevent secure engagement.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Seat the woodruff key fully in the shaft keyway, align the mating component carefully, and secure all fasteners so the assembly locks firmly in place.
