Product review (5 stars): Fits Older Kenmore 80 Series Dryer
Bought this kit for the Kenmore 80 series (probably late 1990s model) when the belt broke.  I replaced all components and it now works like new, much quieter.  The dryer did not originally come with the white plastic roller idler, it had a fixed guide that probably contributed to early failure, but the idler in this kit dropped in and is working fine.  The plastic shims for the rollers are a little tricky getting past the first grove, just be patient and don't deform it too much to get it out of the groove, like I did (I'm easily frustrated).  If the shim does not stay in place because it got deformed, just pinch the three corners with some needle nose pliers.  All in all, glad I went with the kit, I think the roller idler will help the belt last longer.
