I am new here, but have been woodworking most of my life as a hobby (I am a Licensed Clinical Psychologist) and have an unusual problem. After 35 years of use the motor on my JTS10 saw quit. I bought a Leeson motor supposedly set up specifically for woodworking. After getting it mounted and the electrical connection going in the right direction (their directions are backwards, CCW directions ended up turning the blade CW) I had to get a new belt because this motor has the overheat electrical connections on the side of the motor facing the saw rather than on the other side. This prevents the motor from rising to accept the shorter belt. Now I don’t have enough movement for the motor to tighten the new, 1” longer belt.

The motor is mounted on a trunnion system that holds the saw blade. On the end of the trunnions facing the saw (back of the saw) there are bolts on the top of the trunnion and in the face of each – I’m wondering if I can loosen the saw mount and move it back about an inch? buy loosening these bolts? I have them soaking in Kroil now.

Yes of course I’m in the middle of two projects, both requiring my table saw!

I have the same Jet saw—just curious if you were able to resolve the problem? I was going to suggest that you use a link belt and perhaps you could shorten the belt to take up the distance.

What is the model number of the motor you purchased?

What is a jts10. When I’ve had a motor not start when I switch it on the first thing I do is check the breaker. Then I use a multi meter to see we’re the power stops.
What does quit mean? You mentioned that in your post then you started taking about belts and who knows what.

Found out that a motor with the electric input on the right side is not available – so I am having mine rewound – and hopefully it will give me another 35 years. Of course, at 67 years old I’m not likely to be around 35 years from now! My electric company researched for two days and did not find a motor suitable, which surprised me. No, on a one phase motor they cannot be turned around – three phase can. That is – the whole motor can be turned around in the case and the drive come out the other end. Not on a single phase. It’s not the direction of rotation that is the problem, it is that the electric cable and the overheat switch are on the wrong side. Leeson does not make a motor with that configuration and apparently no one else makes a single phase motor like it either.

My JTS10 is a 35 year old Jet construction grade 10” table saw. I decided that I was better off fixing the motor than trying to play with the mount and screw up something else!

Wayne, Have you had any problems with your fence slipping? I have the same saw…

I’m trying to remember if I replaced it 25 or so years ago. I have one face covered with a 1.5” thick piece of oak, on the saw side, and a router table mounted on the wing so a router piece mounted on the other. It is a solid piece, and I don’t think I’ve had problems with it slipping. I replaced the miter with the Vega years ago, love that piece.
