Additional information

This idler arm mounts in the drive system of single-stage snowblowers and pivots as the drive control engages. Snowblower idler arm 580855301 positions the belt correctly so drive power transfers when selected.

If the snowblower slips, does not move consistently, or the belt does not maintain proper tension, the idler arm may be bent, worn, or binding. Uneven belt wear, poor engagement, or visible damage around the pivot area are common signs replacement is needed.

Disconnect the spark plug wire before starting the repair. Support the belt and nearby components as you remove mounting hardware to prevent shifting. Make sure the idler arm pivots freely after installation and tighten all fasteners securely.
