Hello Brenda,
You should be able to take the end off the machine to get to the belts, so many manufacturers made models for Kenmore I can't picture your machine at the moment, on some models you had to take the balance wheel off to get the belt off, if it is possible for you to e-mail me some pictures below I will be able to help you further.
