Model 113.299040

Does anyone have a good tip for getting the key off the arbor?

I have a great running bosh4000 but when this saw came up on CL for FREE DOLLARS i couldn’t help but call and pick it up.

The motor is very clean looking and seemed to start up great. While attempting to remove the arbor to swap the bearings i found the key in the arbor impossible to take off!

I tried to pry it off w/ side cutters, put a torch on it, and tried to wedge it out w/ a chisel. The thing wont move!

Sears parts has the arbor for $60 if I have to cut it off, ouch!

Any advice here?

You can use a Dremel and cut it down the middle lengthwise thus splitting the key and it will come out easier.

soak it in some PB-blaster (this thing stinks, but it can work well in some cases) – it’s a penetrating oil which could help sneak in there and release whatever is stuck inside. then try to force it with some pliers or a metal chisel/pin punch and mallet.

I had a similar problem and found a solution here on Lumberjocks. I used a pair of side cutter pliers to grip the end of the key and then used a small flat screwdriver to pry the side cutters away from the shaft. Between the sharpened edges tightly gripping the key and the large mechanical advantage of the screwdriver so close to the key when forcing the key up, the key shifted and was easily taken out after that. Hope that helps. Took longer to write than to do!

I agree with macatlin1. I’ve used that same technique in similar situations and it worked great.

I free mine up same as PurpLev and toolie. Liquid Wrench or PB-blaster and “help” it with a punch pin and hammer. Works everytime. You should have a woodruff key in that arbor, one with a rounded bottom. They’re the easiest to get out.

I had one stuck in the shaft on my jointer. I put an old screw drive against the end of the key and kept tapping on it until it finally gave up and popped out. I had to buy a new one but that was less than a dollar I think. Acetone and ATF is supposed to work better than all other penetrating oils.

Check this out.

I had one stuck on a table saw I refinished for my dad. I used a chisel and WD-40 and tapped on it until it came out just like Grandpa said. When it came out, it wouldn’t go back in, so i used some 100 grit sandpaper and rubbed on it until it would slide back in there. Worked good as new.

Well I tried all of the non-destructive method above and the thing would not come out. I ended up cutting out the key w/ a dremel…

Good news is now i can get the new bearings on :)
