Additional information

This drive idler arm mounts in the traction drive system and pivots as the drive control is engaged. Snowblower drive idler arm 593192502 positions the idler pulley to tighten or release the traction belt, allowing the snowblower to move when selected.

If the snowblower hesitates, slips, or does not move when the drive is engaged, the idler arm may be bent, worn, or binding. Uneven belt wear, inconsistent traction response, or visible damage around the pivot point are common signs the idler arm needs replacement.

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