I shamefully admit that I haven't used my SS in 2 years. So the other weekend I turn it on to do some sawing and when I tried to adjust the speed, I heard a prang and then the motor wouldn't speed up. I took off the name plate and noticed the ring that moves the speed control to adjust the belt was off. I've been trying to put that darn thing back on, but between I can't my hand inside and not having a third hand I can't get it back on. Back in the good old days SS had store around California, I guess there is no more since Chpt 11. Do I need to remove the headstock and send it back to SS or how do I get it fixed?
Thanks for the help.

Before you put the spring (retaining loop) back on I would suggest that you find out why it came off in the first place. Not using the machine for two years may have caused the control sheave to become frozen on the shaft causing excessive pressure on the spring when you tried to move the speed control. I assume that the machine was running at the time?
You said that the motor would not speed up. By this I assume that you mean that the spindle would not increase speed. Actually the motor always runs at a constant speed and the varying ratio between the two sets of sheaves is what causes the change in speed. Try putting some oil in the oil holes on the sheaves (see the manual) and letting it sit overnight and see if you can get the control sheave(the one with the retaining loop) to move along it's shaft.
With that long of a period of idle time it may be time for a complete tear down and cleaning and lubing to prevent future problems and possible damage.
I put the retaining loop back on by using a small bladed screwdriver through the loop and pressing down on the spring with the tip of the screrwdriver and reaching through the hole with one finger or a dowel to slip the retainer back on. My hands don't fit through the hole either.

One other thing. Please post your location. You may find that you are near enough to another member to get some help.

Bill..... Thanks for the reply and help. I'm located in Bakersfield,CA. I understand about the belt on the pulley changing the speed and not the motor increasing. I guess I didn't explain that well. I've tried to get the lever up close to the shaft to put the retaining loop into the shaft, but can't seem to get it over the spring. Maybe I'm not holding my tongue right. I'll give it some trys.

I have rather big hands and the way I do it is by holding the spring down with a long screwdriver from outside the headstock casting and reaching in with the free hand to slip the retaining loop over it. It's tricky but perseverance will pay off.
Good luck

You need to have the belts and pulleys in the high speed position to be able to do that. I'm not certain exactly how to do that.
That loop is held in a roll pin which is probably now under the motor in the pan. That will have to be found and held in the hole when hooking in the loop.
Before you place the loop over the pork chop.
Check your Private messages. I'm in Bako and should have a little time tomorrow afternoon.

Jim... Are saying the pulleys have to be in high speed location to make this easier???? Then that makes sense as to why I'm having such a hard time. Now to figure how to move the pulleys.

That's the way I was shown to do it. that would mean hand turning the motor/pulley system by hand until you could move the belt outward on the motor sheave. Have to remove the belt cover and using finger pressure pull outward on the idler pulley to allow the belt to go to a smaller diameter. I think it would take 3 or 4 hands to do it at all. Unless someone has a better system.:confused:
