So I was cutting some pallet wood on my 1981 Craftsman contractor table saw when smoke began bellowing out of the throat plate and by the pulley belt. After a short panic, I cleaned all the saw dust from my gravity feed dust collector beneath the saw. Not a single ember was found.
I took the belt off the arbor and gave the blade a spin. Well, actually I tried to give it a spin. With a good flick, I could not get one rotation of the blade. I’m thinking I burned up my bearings. What do you think?

Maybe a sliver is stuck between the arbor and the trunion plate???

Bandit571: Good thought. I will check on that as there was no bearing squeal or blade wobble before the smoke.

Gjd, I had a similar issue but it turned out to be friction on the sawdust but you have checked that one out. Good luck with it.
Would be grateful if you let us know when you find is the cause.

sounds like dead bearings. disassemble, press out and replace, nor expensive but tedious. never done it on a table saw. keep us posted. Good luck

On that model of saw, there is a bit of room near the bearing at the arbor. I have had to clear it many times of thin slivers from cut offs. If one were to wedge inthere, tight, then the smoke will roll, and the blade will not more. Blade friction on the piece of scrap might be enough for the smoke to start, BUT, I would also check the v belts. That is because THAT will be where the smoke comes from. You may have burned some “rubber” in there.

Bought mine new. Never had a bearing problem, yet. The trunion got froze up one year, and split.cracked. Replaced that with parts from another saw, along with a newer double pulley system and a larger motor. The replacement trunion was actually an older model. Still no issues with bearings.

Clean out around the arbor, with the blade removed. Watch when you take the blade off, the culprit might just drop out. Check the belts, too, as they may get glossedover from the burn. They can then slip a bit.

It’s taken a while but I have my TS working again. I disassembled all of the insides of it but could find no reason for the smoke that was bellowing out of it. I have to say it must have been as bandit571 said, a scrap caught in the wrong place. Took the bearings out and they were fine. I ultimately ended up buying a new belt as the original was quite clunky. After a lot of cussing and monkey business, my saw now works as well as when it was new. Amazing what a good cleaning will do to make the tilt and blade height adjustment work with little effort.
