Alliance Laundry Systems Dryer Idler Pulley Wheel - D510142P

Restore proper dryer belt tension with this genuine OEM Alliance Laundry Systems Dryer Idler Pulley Wheel - D510142P. This pulley supports or tensions the dryer belt so the motor can rotate the drum smoothly on compatible Alliance-built dryers.

D510142P is a genuine Alliance/Speed Queen dryer pulley component used when the original pulley is noisy, seized, worn, cracked, or no longer keeps the belt aligned.

Compatibility: Fits select Speed Queen, Alliance, Amana-built commercial/residential laundry platforms where the model diagram calls for this exact pulley number.

Fitment / What To Verify: Verify the full dryer model number, pulley style, shaft/bushing size, belt width, idler arm compatibility, spring/tension arrangement, and whether the belt or drum rollers also need replacement.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Dryer squeals, drum will not turn, belt jumps off, burning-rubber smell, or the motor runs while the drum stalls.
• Visible/Sensory Cues: Flat-spotted pulley, seized bearing, melted pulley face, wobble, rubber dust, belt edge wear, or noisy rotation by hand.

Pro Tip: Replace a glazed or cracked belt at the same time as a failed idler pulley. A damaged belt can quickly ruin a new pulley.
