I have a belt sander Rockwell Shop Series Model # RK7866. It is out of warranty. I have use it for over 4 years with out problem.

Lately the rollers that drive the belt stop spinning, and I have to encourage the rollers to start.

Before I tear into the unit looking for the problem would some one explain how belt sander of this configuration are constructed and where I should start to look to solve the problem. When the belt stops, the disk part of the unit continues to spin. ie motor problem?, drive belt problem?
