HAVE AN OLD 6IN CRAFTSMAN BELT SANDER & I CANNOT KEEP BELT ADJUSTED,AS SOON AS YOU THINK YOU HAVE IT CENTERED IT WILL RUN OFF ONE SIDE OR THE OTHER & DISTROY THE BELT
The Front Roller may have become Hard and the belt won't hold when you adjust just rough up the roller.

Try removing the adjustment screws and applying some Teflon thread sealant. That should prevent the screws from turning on their own. Another thing you can do it check the pulleys with calipers and make sure it is still cylindrical. I have seen ones that become worn on one side. Finally, roughly check the belt tension on both sides and make sure they are approximately the same tension.

You need to adjust the tracking knob which is by the front handle that looks like a triangle head screw. Make sure the belt tension leaver is tight and the belt has enough tension on it. Quickly press and release the start switch and note the centering of the belt. It should be in the center of the bottom platen. If it is not, adjust the tracking knob and bump the switch again. If the belt is going in the wrong direction turn the knob the other direction. Once you are close the center of the platen, press the power switch to turn the unit on and lock the trigger. Firmly hold the unit vertically from the front handle. Fine adjust the tension knob to center the belt and make sure the belt is not hitting the case which will cause damage. You should be able to use the belt sander without the belt slipping off. Let the sander do the work, do not push down and limit the side to side motion. If the belt will not stay on then the belt is too large or the torsion spring needs to be adjusted to applying more tension on the belt and drive roller.
