Replacement Parts

Replacement motors are available on most models, the 85915/85916, and the 85615/85616 are unique.

They come with a pre installed worm on the motor shaft. In an effort to eliminate confusion on which gear ratio you have, review the pictures below and match up the number of leads on the worm.
