Frigidaire Top-Load Washer: Replace Drive Pulley
When a Frigidaire top-load washer spins weakly or not at all while the motor still runs, the drive pulley has usually worn smooth and the belt slips on it. Replacing the pulley is an intermediate job of about 30 to 45 minutes, working from the bottom of the machine.
The drive pulley rides on the transmission shaft, and the belt from the motor wraps it to turn the tub. As the pulley surface glazes, grooves, or cracks, the belt loses its grip under load — the motor spins but the tub agitates weakly or never reaches full spin. It is a gradual failure that worsens as the belt wears matching grooves into the pulley. This procedure is for belt-driven FFTW top-load models; front-load washers use a different rear-accessed belt system.

Before You Start#
Safety warning: Unplug the washer. Machine must be tilted or cabinet removed to access bottom. Disconnect fill hoses to prevent spills.
Step-by-Step#
1. Diagnose the pulley#
Run a spin with a small load. If you hear the motor running at the bottom but the tub never reaches full speed, or the belt squeals and slips, suspect the pulley. Check the belt first — if it is intact and tensioned, the pulley surface is the likely culprit. A good pulley feels slightly textured for grip, while a worn one shows grooves, a mirror-smooth glaze, or cracks.
2. Remove the cabinet#
With the washer unplugged and the fill hoses off, release the cabinet spring clips by slipping a putty knife in about 3 inches from each front corner. Tilt the cabinet back on its rear pivots and steady it against the wall so the bottom is open to you.
3. Take the belt off#
The belt wraps the small motor pulley below and the larger drive pulley on the transmission shaft. Relieve tension by sliding the motor mount where the model allows, or ease the belt off the small motor pulley first, then pull it clear. Inspect it and plan to replace it with the pulley if it shows wear matching the old grooves.
4. Remove the drive pulley#
How it comes off depends on the model. A bolt-mounted pulley has a center bolt — usually a 1/2-inch or 9/16-inch socket — that you remove before pulling the pulley off the shaft, using a puller or two flat-blade screwdrivers if corrosion has bonded it. A press-fit pulley has a set screw in the hub to loosen first; if it is seized, a little penetrating oil and ten minutes helps. Note the shaft keyway or flat that sets the pulley's rotational position.
5. Fit the new pulley#
Line the new hub up with the shaft keyway or flat and push it on until fully seated, then fit the retaining bolt or tighten the set screw. The pulley must sit solid on the shaft — any wobble or play means it is not fully seated and it will fail early.
6. Reinstall the belt and test#
Route the belt around the new drive pulley and the motor pulley and restore tension so it sits in the grooves. Spin the pulley by hand and confirm the belt tracks straight without riding to one edge, which would mean the pulley is not square to the shaft. Stand the machine back up, reconnect everything, and run a full cycle — the tub should reach full spin with no slipping or squeal.
Safety First — Know the Risks
High-voltage components and pressurized water lines create flood and shock risk. A single loose fitting can cause thousands in water damage. Our techs are licensed and insured — let them handle the risk.

Troubleshooting#
- Belt still slips: the belt itself is glazed from the old worn pulley — replace it too.
- Pulley wobbles on the shaft: the hub is not fully seated, or the shaft keyway is damaged — recheck alignment and seating depth.
- New pulley is a slightly different diameter: verify the exact part number, since even a small difference changes belt tension and spin speed.
- Grinding after replacement: a worn transmission bearing, which is separate from the pulley but often shows up once you are in there.
When to Call a Pro#
Call a technician if the transmission shaft is damaged with a rounded keyway or a bend, if the transmission bearings are worn so the shaft itself has play, or if the transmission grinds independently of the pulley's condition.
