Q:

Broken sander belts 315117261 Craftsman Belt sander

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you’re having with the belt sander belts breaking so soon after usage. I know how frustrating that is to have happen.

You didn’t mention, but how old are the sanding belts you’re trying to use? If they are over 6 months old, I think your problem is in the age of the belts. Sanding belts age fairly quickly if the heat and humidity of the area where they are stored varies much. The best policy is to try to use the belts you buy within 6 months after you get them. Store them in a controlled environment area until you use them.

If the belts are new, and if they break along the seam, I recommend checking the belts for directional arrows. If the belts are put on backwards, the belt will break shortly after installing it. If the belt is installed in the correct direction and still breaks, I suspect the spring that tensions the belt is too strong. As you’ve mentioned, there isn’t any adjustment for the belts. 99% of the time for this type of issue, the belts have age, which will cause them to break at the seams. 

If the belt is being ripped, I recommend removing the belt and inspect all the surfaces the belt runs on for sharp edges. If you find any, you can file the sharp areas down. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.
