Additional information

This snowblower wheel axle, part number 738-1166A, holds the wheel in place and provides a stable surface for smooth rotation as the snowblower moves across snow and ice. It installs through the wheel hub and connects to the support assembly, helping keep the machine rolling straight and evenly.

If the axle bends, wears down, or breaks, the wheel may wobble, bind, or fail to spin freely. Steering can become harder, and the snowblower may pull to one side or feel unstable during use.

Disconnect the spark plug wire before starting the repair to prevent accidental startup. If the axle has burrs, corrosion, or sharp edges, wearing work gloves can help protect your hands while handling the part. Confirm the axle is fully seated and secured before reinstalling the wheel.
