Flat Idler Pulley Compatible with Toro Lawn Mower 132-9420 106-2175

This flat idler pulley is compatible with Toro part numbers 132-9420 and 106-2175 and fits a wide range of Toro lawn mower models. The idler pulley guides the drive or deck belt and keeps it at the right tension, so power gets from the engine to the mower blades or drive system. A worn pulley bearing can let the belt slip, squeal or jump off. Replacing the pulley helps your mower cut cleanly and run smoothly again.

• The belt slips, wears out fast or keeps coming off the pulleys
• The pulley wobbles, feels rough or won't spin freely by hand

Installation tips

• Before you remove the belt, take a photo of how it is routed so you can put it back the same way.
• Release belt tension at the idler arm before you unbolt the old pulley.
• Reuse any spacers or washers in the same order, and tighten the bolt securely.
• Safety: Park on level ground, set the parking brake, turn off the engine, remove the key and disconnect the spark plug wire before you work on the deck.
