The tensioner isn't working on our Ryobi BE 321 Type II belt sander. We took it apart and that part seems to be working. Is there another related part we should check?

Remove table assembly.
Remove pointer and then slide cover up and out from dust reflector.
Release belt tension by pushing tension lever toward idler drums.
Note: there may be an arrow on the inside of the belt.
The arrow should point in the direction of belt travel to ensure that the splice in the belt will not come apart.
Slide new belt over the drive and idler drums; center belt on drums.
Push tension lever towards drive drum to tension belt.
Hope this helps.
I tried the model number and can't find it on their site, but if this is a belt sander or planer you can "roll" the new belt in place without loosening anything. If this is another tool let me know and please give me all the information (tool type) and I will check further.
There is a lever on the side at the front right near the roller that you can use to release the spring tension on that roller (moving it slightly to the rear). Once the tension is released you can slip the sanding belt onto both rollers from the side. Release the lever and the spring will put tension on the belt to hold it in place. Use the knob on the left side to center the belt on the roller if it starts to slip sideways when in use.
Is that a BE321VS belt sander? I'm not getting any hits on that number you listed, and Ryobi is a little picky about what model number you use to search their parts database... If it is, try this link to see a page where you can access a parts list. http://www.ryobitools.com/support/parts_batteries Click on the button to go to the Power Tools Parts Store, then click Repair Parts Catalog, then agree to terms and enter the catalog page. Select the Model tab, type 321 in the box and press Search... That brings you to a page listing the BE321VS sander. Select Illustrated parts list and click on belt sander. This will open the parts view. From there you can scroll down to see if that is in fact your sander, and if so, scroll down to part 23, and select the switch (#760390001) and add it to your cart. Now close the window with the part view, and navigate back to the page titled "Ryobi Electronic Parts Catalog" (a tab on your browser), click on shopping cart at top, and when that opens click on the button to proceed to checkout and enter your info and pay, etc. The cost of the switch is $4.44 USD. This web site will only ship to a street address in the US, so let me know if you reside elsewhere....
Check and see if the pulleys on the sander are not glazed this somtimes will cause the belt to slip. Give them a good cleaning. If this does not help there is a good chance the spring on the belt tensioner is weak and need changed.
I have a Ryobi sander with a belt slipping issue as well. The problem seems to be in the design, not on the user end. The drive barrel is made of a semi-hard, non-gripping material. Wood dust becomes a final release agent that breaks any grip that the barrel may have had. To compound the problem, the more the belt slips the smother the underside becomes allowing for greater slippage. I now know why this model was the least expensive unit. >.<
Hi, Consult your user manual for the instructions to install a new belt. Follow these instructions selectively to tighten the belt tension. Here they are....
CHANGING DRIVE BELT
Using a phillips head screwdriver, remove the two screws in the center of the pulley cover. Remove the cover. Raise sanding belt to the vertical sanding position. Next, loosen the hex head set screw. Raising the motor pulley releases the belt tension. Remove the old drive belt. Fit the new drive belt on the drive pulley first and then on the motor pulley. Test belt tension by squeezing the belt with your fingers. Adjust the belt tension with the hex head set screw until there is about 1/4 in. (6 mm) of give. Tighten the belt tension nut securely. Note: Excessive tightness on the drive belt may cause increased noise and overload the motor. Excessive looseness on the drive belt may cause the drive belt to fail prematurely and make a severe chattering noise. Using a phillips head screwdriver, reinstall the pulley cover and the two phillips head screws. Tighten securely.
