The 9040-073-004 is the OEM wide dryer belt for Dexter commercial tumbler dryers. This belt wraps around the dryer drum and drives rotation via the motor pulley system. When the belt breaks, stretches, or frays, the drum stops turning entirely or produces squealing, thumping, and grinding noises during operation. This is a direct OEM replacement that restores full drum rotation and quiet operation. Replaces 5L590.

✓ Installation Tips

Disconnect power to the dryer before beginning any repair. Access the drum belt by removing the front or rear panel depending on your Dexter model. Release tension on the idler pulley, slide the old belt off the drum and motor pulley, and remove it. Route the new belt around the drum in the same orientation, loop it around the motor pulley, and re-tension the idler pulley. Rotate the drum by hand to confirm the belt is seated correctly before restoring power. Inspect the idler pulley and motor pulley bearings for wear while the belt is off — replace them if they show signs of friction or play.

✓ Frequently Asked Questions

How do I know if my dryer belt is broken? If the drum is not turning but the motor is running, the belt has likely broken. You can confirm by opening the dryer cabinet and visually inspecting the belt. A broken belt will be loose or in pieces inside the cabinet. See our Dryer Drum Not Turning guide for full diagnosis steps.

What causes a dryer belt to squeal? Squealing is usually caused by a worn or glazed belt slipping on the drum or pulley. A worn idler pulley bearing can also cause squealing. See our Dryer Making Squealing Noise guide for more causes and fixes.

Should I replace the idler pulley at the same time? Yes — it is best practice to inspect and replace the idler pulley when replacing the belt. A worn pulley will quickly damage a new belt. Contact us for help identifying the correct idler pulley for your Dexter model.
