Topic tags/keywords: question tablesaw refurbishing

I may have messed up. I oiled the motor on my table saw with just plain 3 in 1 oil, and thought ‘what the heck’ I’ll put a drop on the bearings on the arbor shaft. And now it smokes like a chimney when it’s under any kind of load. It doesn’t seem to bog down or lose power, or cut any better or worse or faster or slower, it doesn’t make any odd noises, the belt isn’t slipping, the blade is sharp, it doesn’t burn the wood, the motor’s thermal protection doesn’t trip, nothing in the table saw seems to get hot that I can tell, in fact it seems to work just fine, except for lots of white smoke. I don’t think the smoke is coming from the motor, it’s an old machine and it hangs out the back, seems like the smoke is coming from the cabinet, but I wouldn’t swear to it. It’s an old Rockwell 9” table saw with a 1/2 HP motor, a lower end hobby saw pushing 60 but until now it’s served my purpose admirably. Anybody smarter than me know what’s going on?

Ted – can you have someone cut a board on the saw and you look around
the cabinet with a flashlight to try to see where the smoke is coming from ?
what does the smoke smell like ? wood – electrical – petroleum, etc.
I doubt very seriously that a few drops of 3 in 1 oil would produce as much smoke
as you are seeing. so something else is going on. (the smell could isolate the source).

For right now, I’m on my own, and to make things a more difficult I suffer from anosmia, I can’t smell anything. If I had to guess I’d say petroleum the smoke looks similar to what you might see from cutting oil on a metal lathe or something. I might be able to set up a camera and record what’s going on behind the table saw.

Started smoking right after oiling !
Oil slinging on belt, oil excess oil on shafts burning, you say you put the oil on the shaft How? thru oil cups or just on shaft?
I wouldnt worry to much if it starts to clearup after awhile but if it continues you have something else going on.

Looking forward to seeing pictures of the smoke… and hopefully, it’s source.

My guess is “OIL”... :)

My guess is the bearings are shot. The bearings are running hot and when you added oil, the heat of the bearings caused the oil to burn.

The oil probably thinned the grease in the bearings cups You might just need to replace the bearings and you’d be fine again. But I’ll bet they were ready to retire anyway..

If you can bear it, it looks like the bearings are shot… (big grin)
