Additional Information

The snowblower auger idler arm 770804 helps keep the auger belt under proper tension so the auger engages smoothly and maintains consistent rotation while the machine is running.

If the auger slips, takes longer to engage, or you hear squealing or notice uneven belt tracking, the idler arm may be worn or damaged.

Disconnect the spark plug wire before beginning the repair. Wear work gloves, release belt tension carefully and ensure the new idler arm pivots freely before tightening all mounting hardware.
