618931 Genuine Drum Bearing Sleeve for Bosch, Siemens Clothes Dryers, BSH 00618931 Dryer Drum Bearing Bush Replacement

Part 618931, also 00618931, is a genuine BSH drum bearing sleeve, a plain bearing bush for a clothes dryer drum. We've filed it for Bosch and Siemens dryers that use this number. A worn sleeve lets the drum wobble and scrape, so it's a common repair on older dryers. Check your parts list for 618931 before ordering, as BSH has used several drum bearing designs.

Dryer squeaking, grinding or the drum wobbling?

A drum bearing sleeve is a plain bearing, a bush the drum shaft or spindle turns in, rather than a ball bearing. It's designed to wear slowly over thousands of hours of tumbling. Once worn, the drum sits lower or off centre, so you may hear squealing, grinding or a rhythmic thump, see the drum rub the door seal or felt, notice marks on clothes, or find the belt wearing early. A drum that moves up and down when you lift it by hand points to bearing wear.

Replacing the bearing sleeve

Unplug the dryer and give yourself room to work, as the drum normally has to come out to reach the bearing. Take photos at each step, particularly of the belt path and any wiring. Clean the shaft or spindle and check it for scoring before fitting the new sleeve, as a damaged shaft will wear a new sleeve quickly. Reassemble, turn the drum by hand, then run a test cycle.

Questions about this part

Should I replace the felt seals and belt at the same time?

If they are worn, yes. The drum has to come out to replace the bearing sleeve, so it's a good chance to check the belt, felt seals and drum sliders and replace anything showing wear.
