- Rebuilding the Craftsman 4x36 belt sander. I decided to take a subscribers advice and rebuild my belt sander rather than buying a new one. They are not that expensive, but hey, maybe we can fix this one for peanuts, you never know. In this video we tear it down and find out what we need to do to stop the squealing! Please subscribe if you enjoyed the video!

Pl...
A big thank you Great Plains Craftsman for creating this video! The disassembly was rather simple. It's always nice to know what you're getting into beforehand.
*** For anyone looking for the bearings for the drive roller with the belt pulley on it *** They (both of them) are standard 6001-ZZ bearings (ZZ = shielded on both sides). 12mm ID, 28mm OD, 8mm width
I decided to try 6001-2RS bearings (rubber seals on both sides) to help keep some of the crud out of them, especially on the side opposite the pulley, where the dust collector connects and pretty much will suck crud right through the bearing. My tension pulley was a bit sloppy but I just greased the bushings for now. Will probably be replacing them soon enough. So far so good.
Also worth mentioning, my drive roller was held to the shaft with a double set screw down in the hole... one on top of the other. Had I not read about this possibility, I would likely have beat my drive roller to death trying to get it off since I had already removed the set screw, never thinking there may have been a second set screw down in there below it.
LOL great job, really glad to see you rebuilding it. Now when it is all done and working as it should, if you need a bigger or better sander you can pass on this perfectly fine sander to someone that will put it to great use. Or just keep using it as you did before.
jim stew great idea. You called me out LOL. Had to do it!
I was thinking you should try to fix it when you said you needed a new one, good to see ya go for it.
Great video on how to repair a belt sander. Im off to find part 2. Thanks for sharing!
-Will
Onward to part 2! Nice work btw.
We have the exact same belt sander. Howver, we don't have an issue with it, but your title just told us what size of belt we need to get! Thanks!
Try flashing a little heat on the bearings, they should drop off easy, just keep in mind if it doesn't work quickly the heat will move into the shaft and you will have to let it cool before having another attempt
techron mattic thanks for the tip. Got them off ok, waiting for parts.
Nice work. What kind of motor do these have?
Would have been much more interesting (and helpful) if you had explained more of the "take apart...", but thanks for what information I was able to glean from this.
This video was basically worthless to me because it was already half taken apart!
I cannot even figure out how to get the guard off of my Craftsman model
315.251140 sander.
Where did you find the replacement bushings for the idler pulley and the pulley itself? Having trouble locating online.
Una pregunta donde puedo conseguir las poleas dentadas
I have this sander also - I'm using the motor for another project and don't have the wiring layout for the switch. Would you be able to show how the red, black and white wires are arranged in the switchbox? Thank you!
Great video I have the same Can parts still be purchased? Mine in 18 yrs old Need the 6" Disc Aluminum part. Came loose and broke Thanks
Type the model number into Google and see what comes up.
Yes some sites have various parts. It is really spending time searching. Good luck
I have the same sander that needs the front idler arm brass bushings, they are pressed in as well, I looked on Sears website and it looks like you have to buy the hole pulley but unavailable, any suggestions, where did you get yours? Thanks
I got them from another site, repair clinic I think.
How did you get the aluminum disc sander backing plate off? I have removed the allen screw but now the backing plate does not want to slide off of the shaft. Thanks for the good video.
Never mind, I found a way to pry it off from the inside.
ok how do i get the gard off . its odd to start a rebuild viedo with the first steps not involved. its not helping me much! how do i get the gard off to change the belt im confused?
Just one screw Stephen, you will see it.
@@GreatPlainsCraftsman i dont see it. i have exact same model as your. the guard itself is rubbing the disc. any help would be appreciated.
@@longhornation There is a allen key set screw holding on the disk, the allen key is 1/8". Looking from the top there is a hole in the plastic guard, shine a light into the slot below that hole and rotate the disk until you can see the set screw, loosen it and pry off the disk. It does take some force to remove the disk. I removed my set screw all the way to do it.
@@scotttravis8014 Thank you for answering!! I've spent the better part of a half hour with a flashlight and studying the grainy online parts fiche photo to try to figure it out and I would have spent a lot more time if not for your explanation. That set screw is really buried deep!
@@scotttravis8014 Thank you as well for posting this... I saw the allen wrench on the back of the disk guard just wasn't sure where the mating set screw was hidden. The "look down from the top" was key.
Have one off those. Mine the motor went bad. I wish I could find another motor.
Mine the drive belt a drive pull needs to be replaced.
Did sears did Sears guarantee the bushings for free ? If not nice work on the replacement.
Brian K Shaw Thanks and yes they did.
I have one of these that I need to make a repair to. I can't find the parts I need anywhere. Where did you get the parts?
On line but they are getting hard to find. The bushings and bearings should be available at your local bearing shop. They can get you something that will work
What parts are you needing?
@@derrickwood1453 side disk
Anyone know how many teeth are on the drive pulleys? Sears doesnt make them anymore and I'm looking into finding some replacements
20 on the top one mounted to the sanding belt pulley, 18 on the lower one mounted to the motor shaft.
Where can I get drive pullies and drive belt for the sander You repaired in The video ?
Sears website had the pulley as a complete unit. I googled the belt and found it on line. If you repair the pulley, your local bearing shop should have the bearings and bushings.
Thanks!
Do you have an extra motor pulley (#41, 814105) or do you know where I can acquire one?
No John. Do a web search, try the site Repair Clinic
who is playing the lovely guitar work.? Great repair!
James Colby Thank you. Johann Glossner
Just looked all the parts up ~ SAYS OBSOLETE ~ NOT AVAILABLE ~
Looking myself for bearings so I'll post if I find something and if you have any luck the help would be appreciated.
