old seal was disintegrating

As the instructions say: first remove the drum. In the case of my dryer the drum is supported by two rollers on the back panel and the opening in the front panel. Remove the front panel and the drum almost falls out.

Replacing the seal was easy . Just tear out the old seal, lightly sand the rear lip, stretch the new seal over it, being sure the stitching is oriented properly, and then squeeze adhesive from the supplied tube between the seal and the drum lip.

In putting the dryer back together I couldn't figure out how to thread the belt. I suggest that people attempting this repair take digital pictures of the inside of the appliance before disassembling it.

A very good experience and I prolonged the life of the dryer a good ten more years.
