Q:

How do you adjust tracking. Belt walks off of drum and side knob (tension?) does nothing. 31522670 Craftsman Craftsman 4-inch dustless belt sander

A:

Hello glad to help.  Thank You for choosing Sears PartsDirect.com
 
I am sorry and do understand your frustration when there is trouble with the belt sander.

Glad to help out.   Im  looking at your Craftsman model number 315.22670
 
Sorry about the belt walking off.    Was it dropped or off the table and damage to any part?
 
 To adjust sanding belt, connect sander to power supply.  Place Sander in upside down position.  This position is for adjustments only.  The sander is not in operating position.  Pull switch trigger and release immediately.  Observe tracking of sanding belt.  If the sanding belts runns inward, turn the tracking screw clockwise.  If the sanding belt runs outward, turn the tracking screw counter clockwise.  This should be done until you are sure belt will not run off sander, or come into contact with internal parts.   After installing a new sanding belt, it may become necessary to change the adjustment several times until the belt becomes pliable.
 
When correctly adjusted, the outer edge of the belt will be even with the outer edge of the base of the sander.  Belt life will be greatly increased if a few seconds are spen adjusting the belt tracking.
 
Good luck.
 
 
 If you have further questions please let me know.

A:

I can understand why this information is very important, however I was able to see that this manual is no longer available. While you are waiting for your expert answer, I was able to locate a manual for a sister model. I hope that this will help you.

Q:

how to change belt on sander#31522670

A:

It can sometimes be difficult to work with your machine, but sometimes the answers you are looking for are in your handy owners manual. I understand completely how hard it is to keep track of them. Something that is really handy about Manage My Life is that you can find just about any owners manual. I have attached a link with your owners manual to view how to fill a bobbin. Hope this helps.

Thank you for your question.

Not being able to change the belt can be a concern.

  • In looking at the parts breakdown of this sander it has no lever for pulling back the front spring loaded roller to change the belt. It has a constant belt tensioning.

  • Compress the front roller and roll the sanding belt off the front roller.

  • When installing the new belt put the belt of the front roller first push the front roller against a stop block to compress the tension spring and slide on the rear drive roller.

I hope this will help.

Thank you for using Manage My Life.
