Worked with my ss almost all day. Spent a lot of time in the drill press mode drilling holes in schedule 40 PVC. Stopped several times to clear drill bit and vacuum the table of debris. Out of the blue, the ss wouldn't work. I was working in speed mode D (slow drilling). When I flip the start switch, the motor whines but the spindle and the drive sleeve assembly will not rotate. I removed the belt cover to check for a broken or badly stretched belt. With the belt cover removed, I switched the ss on and found that the control sheave, the floating sheave, and the idler sheave did not move. The drive belt was a little loose but not stretched out of shape or broken.
Anyone have an idea what might be wrong? I bought the ss new in March, 1990 and have had no problems. If the headstock needs repair or rebuilding where does one go the have this done keeping in mind that I'm on the West coast?
This had to happen now just as I had a project planned over the 4th of July weekend.

If the floating sheave on the motor does not move and the motor Is operating, then does the fan sheave rotate? There is only a key to keep the floating sheave attached to the motor shaft. I have never found the key to be a problem. Did you change speed before this happen? Have you been lubicating the floating and control sheave with a few drops of oil? I find the floating sheave may stick when operated at a slower speed for some time. At the slower speeds, the fan and floating sheaves should be spread apart with the belt deep into the sheaves.
Did you remove the Logo cover and check the control sheave and the retaining loop on the quadrant. I would install a sanding disk on the quill and while rotating it, slowly turn the speed control handle toward FAST. The floating and fan sheaves on the motor should slowly close as the control sheave and idler sheaves move apart. I would stop turning the speed control handle and quickly turn the motor on and off to see if the motor belt and control sheave rotates at several speed control points. If the floating sheave does not close while rotating toward FAST, then I remove the motor belt from the floating and fan sheaves and use a penetrating oil on the motor shaft on each side of the floating sheave. Then using your hand or a rubber hammer, push or tap the floating sheave toward the fan sheave. Once I get the floating sheave unstuck, then I use the normal oil hole in the floating sheave and oil it using #10 non-detergent oil (instrument, air compressor or sewing machine) and work the floating sheave in and out with your hands being careful where you place your fingers. Do not let the floating sheave go when in the open position. This is what I find when the Shopsmith stops operating at a slow speed.
Let us know what the results of any further testing

still won't run
Bill, sorry for the long delay but had other projects going, vacation in CT, fishing in Alaska and worked on my golf handicap.
Followed your directions and mounted sanding disk and moved speed dial to fast position. The motor fan sheave and floating sheave moved apart and the idler and control sheaves moved together just like you said. None of those sheave appear to be stuck. Tried to turn on motor and simply got a loud humming sound. Nothing moved! The speed control is ready hard to move when trying to get in slow position (while turning the mounted sanding disk). Oiled floating sheave and oil hole in shaft by quadrant. Still no luck when turned on...just humming sound. Sounds like the motor ceased. Could that be?
I'm afraid the headstock is toast. As much as I hate to admit it, my maintenance schedule was very lame, or non existent really. Should I replace the headstock or have this one rebuilt? Any suggestions where or who? Do you do rebuilds? I would love to know the details and price including shipping from the West coast as you sound like you really know what your doing.
Anxious for your reply cause I need to get going on some real cool Christmas ideas.

rdewinter;
It sounds to me like you have a bad motor...............and a speed dial mechanism that needs some cleaning, lubrication and possible adjustment.
After following Bill's recommendations (as stated ) I conclude that your sheaves are all working fine.
To confirm that I would remove the drive belt from the motor sheave and then turn on the motor (standby to turn it off immediately if it doesn't move).
At this point, removing the motor is simple. Unplug the power. Drive belt has already been removed. Reach up inside and pull the wires (either 2 or 4) off the switch. Take the 5 screws that hold the motor pan in place out of the motor pan. Carefully, the motor is not light. Let it rest on the tubes. Raise the Shopsmith to the drill press mode (lock the table, carriage) just to get it out of the way.
I would have told you too pull the switch out to get to the wires but I always have trouble with the switch removal. If you have the old style switch, just remove the retaining ring and the switch pushes right out (in actually). It then goes with the wires and motor.
Putting the motor back in is just the reverse process. Good luck. Keep us posted.
If you haven't been following the Sawdust Sessions from episode to episode you may want to look them over. Nick has recently covered most of what you have to do to be able to make sawdust again.

Murphy is alive and well. I have had 2 motors with key problems since I wrote the below response. In both cases the fan sheave set screw came loose allowing the key to slide out of the fan sheave. On one motor the fan sheave rotated to where the floating sheave and fan sheave tips ended up on each other and would not close anymore. On the other motor, the fan sheave actually rotated on the motor shaft ruining the fan sheave and the motor shaft. Now I remove the motor from the motor pan on all repair jobs and insure the fan sheave set screw is seated firmly using LocTite. I added this check to my rebuilding check list.
While at the Owner's Weekend, I noticed bottles of Zoom Spout Turbine Oil - 93240 setting around that was beening used for the headstock lubication. I have switched to using this oil. The Zoom Spout makes oiling the sheaves really easy and quick. Thanks, Nick.
