Question and Answers

Q:

craftsman belt sander 315117130

A:

Thank you for your question on the belt sander not turns the sanding belt.

Is the sanding belt tight onto the rollers?

Is the drive wheel spinning on the belt or is the rubber drive on the drum spinning?

Is the release lever pushing the front roller forward to get the belt tight? There should be a coil spring on the front roller shaft that puts tension on the belt with the tension release lever in the forward position.

Please let me know what you discover and we can continue to trouble shoot with the answer to those questions.

Thank you for the update on the sander. It sounds like the drive pulley that drives the rear roller is stripped. You may want to examine the cog belt lower drive pulley. Take the drive belt off and check to see if the drive pulley is slipping on the rear roller shaft. Let me know what you find out. Sam A,

Q:

craftsman belt sander 315117130 ( my reply to Sam A.)

A:

Thank you for the update on the sander.

I think you are going to have to go deeper into the drive system to see what the problem is.

After removing the drive cog belt remove the two drive pulleys and then remove the bearing plate to get to the drive gears number 39 in the picture to see if it is slipping on the drive roller drum shaft.

Reference the image below.

Q:

How do I change the spring on the yoke assembly for a Sears model 315117130 belt sander?

A:

The parts diagram looks like the 2 bushings the rod goes through would keep the spring in place.

Maybe you could drill 2 small holes in the rod and put 2 thin washer and 2 spring pins or cotter keys to locate the spring.
