✅ Cross Reference Information

Common Symptoms

• Drum will not rotate
• Drum rotates intermittently or slips
• Visible belt wear, cracking, fraying, or looseness
• Rubbing or rhythmic belt-related noise during drum rotation

Check Before Replacing

• Disconnect electrical power and, for gas models, shut off the gas supply before inspection.
• With power disconnected, turn the drum by hand and note whether it rotates freely; abnormal resistance may indicate a separate drive-system problem.
• Visually inspect the accessible belt path for breaks, fraying, cracking, glazing, looseness, or displacement from the drum and pulleys.
• If the drum does not rotate, inspect the belt together with the idler and motor-pulley area rather than assuming the belt is the only fault.

Pro Tip

Part Details

Installation Notes

• Disconnect the appliance from all utilities before service and allow hot components to cool.
• Access and installation procedure vary by dryer model; use the model-specific Alliance/Speed Queen service or parts documentation.
• Route the belt around the cylinder and drive components according to the model-specific belt path.
• The Alliance service documentation specifies positioning the belt around the center section of the cylinder, approximately three inches ahead of the rear rib, with the ribbed surface against the cylinder.
• After reassembly, confirm that the belt tracks correctly and that the cylinder rotates normally before returning the appliance to service.
