Topic tags/keywords: question

not sure if I am posting this in right place but I have a craftsman belt sander and the drive belt keeps running off the drive pulley. I got it from a friend who was moving and he told me did not know what to do to make it work. Has anyone had similar or have ideas to fix. All shafts appear to be straight and solid.

Is there no type of a small adjustment Knob or Lever to Adjust the Tracking? I’ve owned 3 BS and they’ve all had an adjustment somewhere. If it keeps running off the Drive Pulley it’s pretty well for sure that it needs Adjustment.

Has to be a Nut/Bolt on the Drive Pulley that you could loosen off and reset. Might even just be Dirt or Something in the release Mechanism that you slacken off to get the new Belt on.

Do you have a Model Number? Apprx. Age? Looked on the www for a Manual?

Not sure on the age, mod #315.11720. Looking for manual find it is actually made by Ryobi all those years ago. The sanding belt stays on fine just don’t find much of a way to adjust drive belt. It may be that I need a new belt which I will try to get locally.

If you don’t have an obvious adjustment knob there may be an adjustment screw right behind the front roller.

I’ve had a similar issue with my belt sander.

I turn the screw so that the belt rides in the appropriate track, but as soon as I apply the sander to some material the belt starts to run off. When I lift the sander off the board it auto-tracks itself back to where it should be.

I find that this only happens with Gator brand 3×18… the Norton brand 3×18 works just fine.

Maybe try a different brand of belt?

this is not a sanding belt issue it is the belt that drives the sanding belt. there is a knob to adjust the sanding belt but I haven’t located any for other belt. Am on quest for a manual which may help some. Think I might purchase new drive belt as well.

So does the belt slip when you apply it to the lumber?

Take it apart and clean it, especially where the tracking knob meets the lever thingy.
