Customer Questions and Answers for Idler Pulley Shaft by Whirlpool

This idler pulley shaft serves as the axle the idler pulley rides on, helping maintain proper belt alignment and tension. Replacing a worn shaft can reduce squealing, wobble, and belt wear so the drive system runs smoothly. What it does:

• Acts as the pivot/axle for the idler pulley within the belt-tensioner assembly
• Helps keep the drive belt aligned and properly tensioned
• Wear or scoring can cause pulley wobble, squeaking/squealing, or belt fraying
• Can contribute to belt slippage and intermittent loss of drive

• One idler pulley shaft

• Disconnect power; shut off gas or water supply if applicable
• Relieve belt tension and access the idler assembly
• Note and transfer any spacers, washers, or retainers from the old shaft to the new one
• After reassembly, the pulley spins freely on the shaft and the belt tracks correctly
