Additional information

This snowblower splined axle lobe fits onto the splined section of the axle and provides a mounting point for drive or wheel components that require a keyed connection. Part number 581645101 helps ensure torque transfers correctly so the drive system responds as expected during snow clearing.

If the splined axle lobe wears, cracks, or becomes loose, the connection between the axle and driven components can slip or fail. You may notice uneven drive response, loss of traction, slipping under load, or unusual vibration during operation.

Disconnect the spark plug wire before starting the repair to prevent accidental engine startup. Align the splines carefully during installation so the lobe seats fully and the mating component engages securely before tightening all fasteners.
