Typically what happens is the sheaves don't move which causes your speed control issues and a belt getting jammed.

And the one which causes the quadrant gear wear/pivot bending is the floating sheave(motor shaft).

I was pleased to see how clean the inside of the headstock was - very little sawdust. I lubed everything, but probably had less than 10 hours on the machine since its last maintenance.

Why the discourse re: oiling? see your question in your post #6. "What's the secret for keeping the spring behind the speed dial in place? As careful as I was, when I was cleaning up I found the spring on the floor!"
I'll have to wait until tomorrow to do the high speed adjustment, and replace the speed dial spring.

Like others said - other issues happen when past oiling has been stingy. Many of us don't realize the effect sticky motor sheaves have on the speed control mechanism. So - therefore went with the oil commentary.
Although you may not need to be reminded - this is a forum with lots of newer members.

Remove the clip off the quadrant.

Remove the speed control(this allows opening the sheaves so the belt can be freed).

Raise the belt away from the idler pulley(control and idler sheaves).

Set the speed control to 'fast'. There is a high speed stop. This places the quadrant towards the dial. Reinstall the speed control. Position the outer ring to 'fast' and reattach the knob. Make sure the set screw seats in the depression in the shaft.

Place the loop over the clip on the quadrant gear arm.

Lower the motor belt onto the idler pulley and then onto the motor pulley.

At this point you should be able to rotate it all by hand.
So when installing the quadrant it has to be on slow or fast?

Should I put the speed control back in on slow or fast. Is the quadrant open or shut when installing? that's the question

FAST
Quadrant AWAY from the idler pulley

Control sheave 'OPEN'.
