Can the tracking on the sanding belt on the B&D belt sander 5.2A be adjusted?

yes ther should be a knob on the top front roller (top side) this should affect tracking , also make sure tension taker (lever for changing belt) Is fully off so that belt gets its full tension , if the belt doesnt get full tension it will walk side to side

The sandpaper works its way off the machine almost immediately after turning machine on. We already checked to see if the paper was the right size. We also made sure the tightening lever was secure.

If this is a belt sander then they have a tracking adjustment knob. You will need to adjust it so that the belt stays on and doesn't want to walk off.

Sanding belt seems loose and sometimes gets stuck riding where the vacuum sucks the dust from is there a way to make it tighter without lowering the bottom adjustment for where the belt meets the wood?

  1. Check and make sure you have correct air pressure and that air pressure is adjusted correctly
  2. Check that the air valve is on
  3. check that the lock screw is tight
  4. check and adjust the belt tracking and oscillation
  5. Check the platen graphite strip and felt pad for wear
  6. The Manual for this unit can be downloaded HERE

My Makita 9901 belt sander is used but very slightly and now is just frustrating to even use. What is the most common cause for tensioning roller to keep pulling the sanding belt over against the housing?...

There is a screw that changes the angle of the roller to change the tracking of the belt... this is very sensitive and probably if you are having trouble is more a reflection of the belt quality then the sander...try different belts before you toss the sander... I have had one for years and love it... although the belt tracking is tricky sometimes anss your have to keep after it...
The adjust ment is very touchy only turn it maybe 1/8 turn at a time...

My Makita 9910 sander has the belt jammed. It started to walk sideways until it got jammed under the plastic at the edge. I can't move it after releasing tension. In fact now I have torn the sodding...

There should be a lateral running adjustment knob that corrects for this problem. It's too late for the current belt--get it out any way you can. Once you have a new belt in, bump the power button and try to correct the tracking in bursts. Once it is tracking, make only minor changes in the tracking adjustment so that you don't over-correct. Good luck!

After installing new belt, on Porter Belt Sander 352VS #6 the belt drifts of to one side until it comes completely off. How do I stop this?

There is a tracking adjustment knob on the side of the sander--adjust one way or the other until it tracks properly. This is something that will change by itself as the sander is being used--check periodically.

Belt will not tighten small round spring come loose do not no where it goes

Usually there is a knob with a screw imbedded with a spring around it that screws in and adjusts the "tracking" of the belt so it doesn't run off the side of the rollers. If you lose that screw, then teh belt will come off quickly.

At this site, look at part # 68, 69, and 70

Tool Shop Belt sander - can't align belt tracks to thee inside

The problem is that you have not set the adjustment properly. Back off the adjustment screws,slide on the belt and center it over both rollers, addust a little at a time both screws, after belt begins to tighten up stop adjusting. Turn the power switch on for about 1 second. Is the belt tracking? Adjust as necessary. Try the power again for longer and longer periods untill belt tracks in the center of the rollers. Tighten nuts to keep adjustment screws from backing out.

Slipping belt

OK the belt tensioning mechanism is spring loaded. First what is the quality of the belts are they real flimsy or stiff. You say the rollers spin but my question does the rear roller still spin and the belt remain stationary. If so the rubber belt on motor is bad. I would take a look for excessive wear on the rear roller. Does the yoke mechanism snap forward or move slowly, look for a build up of sawdust in this area that might be restricting movement on the yoke. The wear plate in still good condition. One other thing on the belts are they directional? Do they have an arrow on the inside if so that has to point toward front of tool. I looked at a breakdown and could not see anything else to suggest. I never had this problem except with belts when I was at Makita.
