XPARTCO 8066184 Dryer Motor Pulley Replaces WP8066184
The XPARTCO 8066184 is an aftermarket replacement dryer motor pulley compatible with a wide range of Whirlpool-family dryers including Whirlpool, Kenmore, Maytag, KitchenAid, Amana, Roper, Crosley, Estate, Inglis, Admiral, and Magic Chef. The motor pulley is a small but critical metal component that threads onto the dryer motor shaft and serves as the anchor point for the drive belt. As the motor spins, the belt wraps around the motor pulley to transfer rotation to the drum via the idler pulley. When the motor pulley cracks, strips, or breaks, the belt loses its anchor point on the motor side — the drum stops spinning even though the motor continues to run.
Made from durable metal, this motor pulley measures 1-1/8" L x 1-3/8" W x 1-1/8" H and is designated Pulley 29 (60Hz). It threads onto the motor shaft with a left-hand (reverse) thread — it tightens clockwise and loosens counter-clockwise. It directly replaces WP8066184, 8578565, 3389627, 3394341, 3401143, 694871, W10299847, W10290525, W10290531, W10402909, and WP8066184VP. Installs in 30–45 minutes with basic hand tools including a wrench.

Installation Notes
⚠️ Unplug Dryer Before Starting — Left-Hand Thread: Loosen Counter-Clockwise Disconnect power (and shut off gas for gas dryers) before beginning. Remove the top panel and front panel to access the motor and drum area. Release the drive belt tension from the idler pulley and slide the belt off the motor pulley. The motor pulley threads onto the motor shaft with a left-hand (reverse) thread — to remove it, turn it counter-clockwise (which is the tightening direction for standard threads). Use two adjustable wrenches or a wrench and pipe for additional leverage if the pulley is stuck — a penetrating oil applied and allowed to soak for 10–15 minutes can help free a seized pulley. Once removed, thread the new 8066184 pulley clockwise onto the motor shaft (which tightens it due to the left-hand thread) and snug it firmly. Re-route the drive belt around the new motor pulley and idler pulley, reinstall the front and top panels, restore power, and run a test cycle. Tools needed: Phillips screwdriver, two adjustable wrenches or pipe wrench.
Frequently Asked Questions
What does the dryer motor pulley do?
The motor pulley is a small threaded metal wheel that screws onto the dryer motor shaft. The drive belt wraps around the motor pulley on one side and the drum on the other, with the idler pulley maintaining tension. As the motor spins, the motor pulley rotates with it, pulling the belt and turning the drum. Without the motor pulley — or with a cracked or stripped one — the belt has no grip point on the motor side and the drum will not rotate even though the motor is running normally.
Why does this pulley have a left-hand (reverse) thread?
The motor pulley uses a left-hand thread so that the motor's rotation naturally tightens the pulley during normal operation rather than loosening it. Since the motor spins in a direction that would loosen a standard right-hand thread, Whirlpool designed the motor pulley with a reverse thread to prevent it from backing off and falling loose during use. This means: to remove the old pulley, turn it counter-clockwise (opposite of standard). To install the new pulley, turn it clockwise to tighten.
What is the difference between 8066184 and WP8066184?
These are the same motor pulley. WP8066184 is the updated Whirlpool OEM part number that superseded the original 8066184. The 8578565 and 3394341 are also cross-references for this same pulley from earlier production runs. This aftermarket replacement is compatible with all of these numbers.
Should I also replace the drive belt and idler pulley at the same time?
Yes — since the dryer is already disassembled, inspect and replace the drive belt (341241) and idler pulley (279640 or W10837240 depending on your model) at the same time. A broken motor pulley often damages or frays the belt, and the idler pulley bearing wears at a similar rate. Replacing all three together in a single repair eliminates the most common drum drive failure points and prevents a repeat teardown in the near future.
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 metal to match the dimensions and thread specification of the original WP8066184 motor pulley.
