Product review (5 stars): making this repair kit a great addition for a total overhaul
The price of this repair kit was the same as a locally provided belt, which made this repair kit a favorable option. This kit was used on a Kenmore Series 90 dryer, Model: 110-66902691.  The kit was ordered at the same time as a replacement motor, making this repair kit a great addition for a total overhaul.

This kit included the following parts necessary for a complete fix:
1 each belt
1 each replacement tension wheel with washer
4 each replacement carrier wheels
9 each triangle clips

The replacement triangle retainer clips appear not as heavy duty as the original clips, but are sufficient in performing the job. As per a recommendation from another post, I used brake fluid to clean all the wheel axles.  After the repairs were complete. the dryer appeared to perform more quietly.
