XPARTCO W10837240 Dryer Idler Pulley
XPARTCO W10837240 Dryer Idler Pulley
The XPARTCO W10837240 is an aftermarket replacement idler pulley assembly compatible with select Whirlpool, Maytag, Amana, Kenmore, KitchenAid, Crosley, Admiral, Inglis, and Roper dryers. The idler pulley maintains correct tension on the drive belt, allowing the belt to spin the dryer drum smoothly and consistently. When the idler pulley wears out, the belt loses tension — causing squeaking, grinding noises, or a drum that stops spinning entirely.
This complete assembly includes the idler arm, pulley, and bracket — everything needed for a direct drop-in installation. The pulley is 2-1/8 inches in diameter and the overall assembly measures 6-1/4" L x 1-1/4" W x 3-7/16" H. It directly replaces OEM part numbers W10837240, W10547287, and W10547290, and fits Whirlpool-family dryers with the lint screen located inside the door. Installs in 15–30 minutes with basic hand tools.

Installation Notes
Frequently Asked Questions
What does the idler pulley do?
The idler pulley is a spring-tensioned wheel mounted on an arm and bracket inside the dryer. It presses against the drive belt to maintain the correct tension needed to keep the belt gripping the drum and motor pulley. Without proper tension, the belt slips, loses contact, or causes the drum to stop spinning. A worn or seized idler pulley is one of the most common causes of dryer squeaking and drum spin failure.
Does W10837240 replace W10547287 and W10547290?
Yes. The W10837240 is the updated part number that directly supersedes both the W10547287 and W10547290 idler pulley assemblies. If your dryer originally used either of those older part numbers, the W10837240 is the correct current replacement.
How do I know if my lint screen is inside the door?
Open the dryer door and look for a slot or housing just inside the door opening — typically at the top or bottom of the door opening — where you pull out the lint filter. If the filter pulls out from inside the door frame, the W10837240 is designed for your dryer style. If the lint screen pulls out from the top of the dryer cabinet, contact our support team with your model number to identify the correct idler pulley for your machine.
Should I replace the drive belt at the same time?
Yes — since the dryer is already disassembled to replace the idler pulley, it is highly recommended to also inspect and replace the drum belt (WPW10112954) at the same time. The belt and idler pulley wear together, and a worn belt on a new pulley — or vice versa — significantly shortens the life of the new part.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured from durable plastic and metal to match the dimensions and performance of the original W10837240 idler pulley assembly.
