Additional Information

The snowblower idler arm, part number 723409, holds the idler pulley in place and helps apply the correct amount of tension to the drive belt as it moves between pulleys. Proper tension helps the belt track correctly and maintain consistent power transfer during snowblower operation.

If the drive belt slips, squeals under load, or drives inconsistently when you engage forward or auger functions, the idler arm may be worn, bent, or the pivot points may have excess play. Uneven belt tracking, frequent belt dislodging, or unusual noise from the belt area can also indicate idler arm issues.

Disconnect the spark plug wire before beginning the repair. The idler arm installs near rotating pulleys and belt components, so work gloves can help protect your hands during removal and installation. Make sure the idler arm moves freely through its range and that the belt tracks smoothly before reconnecting the spark plug wire.
