D511255P Genuine 5 Rib Belt for Speed Queen Laundry Machines, Speed Queen Multi Rib Drive Belt Replacement Part

D511255P is a genuine Speed Queen belt with a five rib profile. Multi rib belts like this run in matching grooves on the motor pulley and the driven pulley, giving a strong grip in a compact width. Our record lists it simply as a 5 rib belt and doesn't name the Speed Queen models it suits, so check the number in your parts list. Belts that look alike can differ in length.

Speed Queen belt slipping or broken

The belt transfers power from the motor to the part it drives, whether that's a washer drum or transmission or a dryer drum. Over time the rubber hardens, the ribs crack across, and the belt stretches, so it starts to slip under load. You might hear squealing on start-up or spin, smell hot rubber, see black dust around the pulleys, or find the motor running while the drum barely turns. A snapped belt usually means the motor hums or spins freely with no drum movement at all. Check the pulleys for wear or damage while you're in there.

Fitting a Speed Queen belt

Unplug the machine, and turn off the taps if it's a washer. Photograph the belt routing before removing the old one. Ease the new belt onto the smaller pulley first, then roll it onto the larger one while turning by hand, making sure every rib sits in its groove. Run the machine empty to check it tracks straight without squealing.
