How to remove gear from arbor shaft on cut off saw?

I need to replace the arbor shaft bearing on my cut off saw. There is a gear on the shaft with a feather key but no set screw and the gear will not come off the shaft. I've smacked it pretty good with a hammer with no movement and I'm concerned if I hit it too much I will deform the other end of the shaft and it won't fit back in it's bearing.

Any suggestions on removing this gear?

The fact that there is no screw suggests its a push fit. Without knowing the machine, I am taking an educated guess, but suggest you will need a hydraulic press.

First guess would be a lock bolt is tightened down. Second guess would be a 90 degree latch or stop. Take a look at this link from "mikestools": http://www.mikestools.com/download/Jet-Owners-manuals/Jet%20Tablesaws/708661.pdf.

Loose pulley arbor


I had a similar problem and after removing the suspect pulley I discovered that the threads for the set screw were not tapped all the way through. The set screw would tighten but not go far enough to lock on the key. With the pulley off the arbor I forced the set screw until it threaded well into the key way. I had to use quite a bit of force to get it to go but it finally pushed through the last portion that was unthreaded. Then I reinstalled it on the arbor with the key and tightened it. It has been months now of steady use without any movement.

You probably need to replace the bearings on the arbor shaft. If you have the means to disassemble and press the bearings off, and you can precisely measure the ID, OD and Width of them (there will be two of them and they are probably both the same) you can buy replacement bearings on-line pretty cheap. Make sure you buy sealed bearings. These will be standard bearings, which you don't have to buy as replacements from Sears.

My jet table saw has excessive vibration.


Sounds to me like the arbor bearings have too much play, or one of them has failed. With the saw unplugged, see how much play there is in the blade by pushing it side to side and up and down. Remove the blade and grab the arbor with your hand and see if you can move it any direction. You should have virtually zero play. If that is the problem, major disassembly is required. If you have a pair of reasonably precise calipers and you get the bearing removed, there are several bearing distributors with good websites to find replacements pretty cheap. If only one bearing is bad you should replace both anyway. Good luck!

I have a powermatic 66 table saw. I removed the motor, to move the saw. when i reinstalled the motor, the blade has moved 5/16'' towards the fence.


Check to make sure the arbor set screw is not loose. The bearings may have shifted when you moved it. I recently rebuilt an old 66. Repositioning the bearings and tightening the set screw could be all it needs.

Arbor pully and motor pully kepts working loose no mater how much i tighten set screws


you might want to check the inner bore on the pulleys and the arbor shafts for wear. The pulleys should be somewhat of a snug fit. Then if they are OK I would replace the set screws and when reinstalling use some looctite/thread sealer to keep them from loosening. (BLUE) should work well for this.

I have a 1/16" tilt


Your question is not very clear. Here are several answers.
By tilt you may be speaking of bevel adjustment 0 - 45 Some saws have hidden under the table or obvious positive bevel stops or screws in the table top for 90 and 45 degree. Adjust them.
You may have a bent or warped blade causing the "tilt."
Thin blades may be stiffened with blade stabilizing washers $14
With the saw unplugged remove the blade. Grab the threaded arbor shaft and pull it up and down. Next push the shaft straight in and out. If there is wiggle the bearings are worn and may need replacing.

The nut is binding on the arbor because the threads are buggered up or clogged with something. It could be the nut (which is probably brass and soft) or the arbor (which is steel). If it got a little cross threaded, the damage will be on the nut. It might be the arbor if the arbor took a whack. Once you have it apart you should be able to see it - although the damage might be pretty small. You aren't likely to have a tap and die to run through the threads, but you can probably fix it with a little rotary tool (like a dremel) using a small disc. If it is the arbor you can use a triangular file. Or you can buy a new nut. I hope this helps.

I have an old craftsman table saw. i believe the "brake" or gears a shot. the saw runs very loud and shakes. now no matter how much i tighten the blade the nut loosens after one cut.


With the saw unplugged and the blade tightened, using your fingers try to wiggle the blade side to side and lift it up and down. Other than a little flexing of the blade, there should be no movement. If you have much movement you have a problem and the saw is dangerous. If this is a belt-driven saw, then you may be able to replace the bearings on the arbor (the shaft the saw mounts to) or you may have to replace the whole arbor. If this is a direct-drive saw (the saw mounts directly on the motor shaft) then the bearings that have failed are in the motor and you are less likely to be able find and install replacement bearings. If you find the model number of your saw, you might be able to find drawings and replacement parts on this site:
