Part WP6-3700340 Dryer Idler Pulley / Bearing Assembly
Purpose
Tensions belt and supports drum rotation
Details
This is the genuine OEM idler pulley used in many Whirlpool-family dryers. It maintains correct tension on the dryer belt as it wraps around the motor and drum, enabling the drum to spin freely. When the pulley bearing wears or seizes, you may hear squealing or grinding noises, or the belt may slip or break. Replacing the idler pulley restores proper belt tension and smooth drum rotation.
Included Items
One idler pulley with bearing and mounting (shaft/bracket) assembly.
