Additional information

This snowblower planetary friction wheel hex shaft assembly, part number 918-06072, includes a hex-shaped shaft and the friction wheel mounting surfaces used in a planetary gear system. The hex shaft helps prevent slippage, while the assembly provides the pivot and contact points for friction wheels that help distribute torque and control speed within the drivetrain.

If the friction wheel hex shaft assembly becomes worn, bent, or damaged, the friction wheels and related planetary gear components may not engage smoothly. You might notice noise, vibration, resistance, or inconsistent torque transfer when the drivetrain struggles to engage or hold a selected speed.

Disconnect the spark plug wire before starting the repair to prevent accidental startup. Gearbox and friction wheel areas can have sharp edges, so wearing work gloves can help protect your hands during installation. Make sure the assembly is aligned correctly and seated fully with all fasteners tightened before returning the snowblower to service.
