Additional Information

The snowblower keps nut, part number 727479, threads onto a matching bolt or stud and includes an attached lock feature that helps resist loosening under vibration. Proper use helps keep assemblies secure and aligned during snowblower operation.

If fasteners loosen over time, you hear rattling near connection points, or a bracket shifts under load, a worn, missing, or loose keps nut may be allowing hardware to back off. Difficulty tightening or a nut that spins freely without gripping can also signal issues with the nut or mating threads.

Disconnect the spark plug wire before beginning the repair. The keps nut installs near metal edges and moving parts, so work gloves can help protect your hands during removal and installation. Tighten the nut securely without overtightening to avoid thread damage before reconnecting the spark plug wire.
