Belt Replacement Instructions

    When I broke my belts installing a zero-clearance throat plate, the search engine was down. The tech place where I bought the replacement belts didn't provide much help or direction.

    For those who have the problem later on, here is the procedure I figured out, which is quite fast:
    1. Unplug the saw.
    2. Remove the six screws holding the angled cover onto the left side of the saw and remove the cover.
    3. Remove the seven screws holding the dust cover on, then remove the cover.
    4. Remove the saw blade, guard, arbor spacers and nut.
    5. Remove 4 screws holding the slides together.
    6. Remove the 2 screws holding the arbor bearing in place. Pull straight out on the bearing assembly, exposing the two shafts and belt area.
    7. Fabricate a "spoon" tool. I used a foot-long piece of regular electrical conduit and made a 1" cut lengthwise through the middle of the tubing, then cut off one of the halves, creating a hollow tube / spoon lever or pry bar.
    8. Start the first belt with about 1/3 of its edge halfway onto the upper shaft (left side), and hold it with your left hand. Stick the spoon tool through the free end of the belt (hollow side toward the shaft) and using a right-handed circular motion, pry the bottom of the belt onto and around the lower shaft, while turning the upper pulley clockwise with the left hand. Once the belt is started on both shafts, prying with the tool in a circular motion on the lower shaft will stretch and work the belt back onto the shaft. Then, turn the upper shaft with a wrench or other tool.
    9. Repeat this process 3 or 4 times until the lower belt is seated. Remember, while you are turning the upper shaft with a wrench, as long as you hear a "snapping" sound, the belt is still moving back onto the upper shaft.
    10. When the first belt is all the way to the rear of both shafts, repeat the process with the second belt. When done, the second belt will be exactly flush with the outer edge of both shafts.
    11. If you haven't done so already, clean off all sawdust, etc. from everything.
    12. Using a dab or two (small) of wheel bearing grease or Vaseline, align the two flat shims onto the motor. (You should be able to tell the correct orientation by the wear marks on the shims). The two shims with the 90-degree bend mount onto the arbor bearing housing; again, their proper orientation can be determined by friction marks.
    13. Working carefully, just start the two screws holding the arbor bearing onto it's back plate. Then start the four screws holding the entire arbor bearing assembly. When all are started properly, tighten the two bearing screws alternatively, then tighten the other four screws last.
    14. If still needed and you are careful, mount the blade and the zero-clearance throat plate. After checking that the blade rotates freely, not binding on the throat plate or saw body, plug in the saw, turn it on, and by gradually raising the blade, cut the slot in the throat plate while you can see what's going on. (Wear glasses, because plastic bits will fly everywhere!)
    15. When done, re-install the dust catcher and the end panel and you are done! Total time 20-30 minutes, depending upon speed and dexterity.

      Thanks a lot!!
      The Craftsman appears to be identical to BT3000. Documentation from Sears and Ryobi was not at all clear so we were pretty concerned. I think this will be VERY helpful. I'll let you know if we discover anything during final re-assembly of the Sears saw.

  • Lonnie's No Measure Alignment procedure
    By member Lonnie in Orlando
    Hi Guys -

    I haven't been on the forum much lately ... I bought a '55 MGTF-1500 that is taking up space, time, and money that is(was) used by my woodworking shop. The car has a wood frame beneith the body panels, so I guess it counts as woodworking.

    Thanks for resurrecting my No-Measure alignment thread. I see that it has lost some of the attachments. So I reposted it below.

    Note - there are a lot of good ways to adjust a BT3K or any other table saw. This is the one that I found is best for me. Any method that achieves the intended result is just as good.

    I set my rip fence to be parallel to the blade. I rip on both sides of the fence (bevels, size of workstock, etc.), so a setting that will allow extra space on the outfeed of one side of the fence could bind the stock on the other side of the fence. The No-Measure tool is easy for me to use for initial setting plus is a fast way to check that the fence is still in alignment.

    TIP: When you determine which direction the rip fence needs to move to get into alignment, and before you...

  • BT3K Shim Replacement
    By member Black wallnut
    Since it seems time for my semi-annual maintenance and due to several posts asking how to lately I deciced to take pictures during mine. Keep in mind this is specifically for the BT3000 only.

    Step 1: double un-plug saw at outlet and onboard outlet. Remove throat plate, Sharkguard, Big dog clamp, and splitter (or the stock POS []). Remove blade and spacers.

    Step 2: remove left side cover and dust shroud.

    Step 3: remove the four...

  • BT3000 To 3100 Shim Upgrade
    By member crokett
    Upgrading the shims avoids the issue of the BT3000 shims dropping out and causing the blade-raising mechanism to bind.

    Before you begin:
    Call Ryobi technical support at 1-800-525-2579 with the serial number from your saw to
    verify that your saw is eligible for the upgrade. Some earlier BT3000s are not.

    ‘Right’ and ‘Left’ designations assume you are starting by looking at the front of the saw.
    These instructions assume a stock saw with no modifications to the blade guard assembly
    or saw body.

    Parts you will need for the conversion:
    2 each 0181010314 spring shims BT3100 part $0.43 ea
    1 each 0181010110 guide holder BT3100 part $15.07
    When you order these parts to save on shipping costs, it is recommended that you also
    order the following parts. Inspect the flat shims and belts and replace if necessary while you have
    the saw torn down. It is a good idea to have the belts on hand as spares.
    2 each 969600001 flat shim BT3000 & BT3100 part $0.45 ea
    2 each 662329001 belt BT3000 & BT3100 $13.49 ea
    You can order from,,

  • Stripped elevation and Helicoil installation
    By member richclemson
    So I rushed out and bought my first table saw, than discovered this site and all the helpful information "like how to buy a BT saw). What I didn't know was I had an elevation problem. The screw that runs from the 90 degree bevel gears up through the aluminum motor housing was badly worn. Once I had the two parts out of the saw, the damage to the aluminum threads was worse. After a little help from others on this site, I choose to put in a helicoil. The attachments show the pictures and how to. Of note, I would...
