Topic tags/keywords: jet supersaw jwss-10lfr timing belt eccentric shaft elevating worm broken table saw tool repair

I purchased a used Jet Supersaw in excellent condition. It worked perfectly when I bought it. I brought it home in a truck without any problems. When I tried to raise the blade it would not raise. Opened up the saw and found that the upper Timing Pulley (#67) had fallen off. The silver shaft is the housing (Eccentric Shaft #28). Inside this shaft is the Elevating Worm (#25) which held the Timing Pulley. But now the Elevating Worm has moved into the Eccentric Shaft (silver shaft in picture) and now the Eccentric shaft is about 1/4” inside the housing. I need to get it out to connect the timing pulley. I have attached pictures an the schematic of the saw. Any ideas how to proceed? Thank you!

Can’t you push the worm shaft from the other end to get it to stick through where you can get the pulley installed?

Thanks for your suggestion. I was not able to do this….

But, I figured it out….just in case anyone else ever has this problem…

You need to flip the saw upside down…it takes the weight off the shaft… and then you can push it through… Simple solution…but if you do not flip the saw you will never get it to move.

I’m a little late to this conversation and I assume you have solved this problem by now but next time a lift belt breaks…and it will…you can disconnect the drive belt and lift the arbor by reaching through the large door on the back of the saw. When you lift the arbor, it pulls the gear away from the worm gear. Then you can push the shaft back through. If you have the shaft and worm gear in your hand, go ahead and replace the tapered pin that joins the worm gear to the shaft because it will shear eventually too. The designers neglected to put a lock collar on the sprocket side of the shaft to secure the worm gear assembly.

As you can tell, I have been through this saw recently and I am underwhelmed with the overall design of the machine.
