Topic tags/keywords: band saw repairs wheel

I purchased my first band saw over the summer and have only used it twice. I was given some extra blades along with my purchase. I wanted to change the blades to test how some of the smaller ones worked etc,. However, I began having some problem getting the new blade to stay on the wheels. After spending some time trying to get the new blade on, i left the saw alone for a few months. Last week i returned to my band saw for a rematch. This time, it resulted in disaster! I played around with the knob where “height adjustments” are made then SNAP! a metal piece fell off the saw. I took apart some of the parts to try to remove the wheel, but cant get the top wheel off. I plan on using some sort of epoxy to reattach the broken piece.

Will someone please advise of what to do. How do i remove the wheel?

Don’t epoxy a metal part! especially a moving part. It’s a SAFETY issue. buy a replacement part

Is that the bottom piece of the upper hinge assembly? (That’s the piece you crank on to tighten the blade, and then adjust a knob in the back of the saw to make the upper wheel tilt forward/back.)
If so, it breaks a lot because they are made with cheap pot-metal. They take a lot of pressure and epoxy isn’t going to fix it.
Search this forum and you’ll find a couple of threads where someone machined a new part, or a replacement part can be bought online.

If you search the model # online you should be able to find at least an exploded diagram fairly easily. If it’s not a press fit then there should be a bolt right in the middle that holds the wheel onto the shaft (which should be sticking out from that upper hinge assembly).

Looks like the shaft hinge broke. It is part #85 in the manual.

It looks like there is a nut and two snap rings that retain the upper wheel.

Good luck

Did you look and see if it’s a press fit or if it has that bolt in the middle? You’ve got it hidden in the pic:

If it’s a bolt then it’s probably LH thread. If there is no bolt then it’s probably just bearing pressed on like David said you just use a puller.
That’s all I can offer without a model #.

I think what you are looking for is available here:

http://www.ereplacementparts.com/jet-jwbs14os-708113a-14inch-woodworking-band-saw-parts-c-32652_32684_155040.html

It is the part A-34. I had one of those break on mine and I ordered one and replaced it and everything has been fine.

Thanks for all your feedback. It looks like both suggested parts will work, only question is the material that they are made of that would require some extra research. Luckily it is a $10 part!
