Removing and adjusting the speed dial

I watched the "sawdust session" video #24, where Nick Engler replaces the speed control.

I don't need to replace the speed control; I just want to adjust the speed dial.

Do I need to remove the belt & unlatch the cam before I can loosen the 3/32 set screw and remove the speed dial? Or can I just loosen the 3/32 set screw & remove the speed dial? (The speed indicator ring is not moving reliably. The speed control mechanism works fine, that is, I can spin the speed up and down, but the indicator ring sometimes does not rotate while I'm adjusting the speed).

Thanks!

Yes! You will 'discover' either stripped teeth on the small spur gear on the control or that it was not meshing with the gear on the indicator ring.

The set screw is in a depression(hole) in the shaft, so it will not pull out off the shaft unless you back out the setscrew a little further after it becomes loose. Make sure the set screw goes back in that hole when it is reassembled. It is easy to booger up that shaft, so do be careful when tightening the set screw. A boogered shaft may be the cause of your 'problem'. File any rough spots until the shaft is back to normal size.

No, you do not need to pull the belt to do what you want. Run the unit up to high speed and position the access hole near the top so that you can gain access to the set screw.

Once you have the Speed Control Dial off, you will be able to inspect that small gear and dial ring and you will be able to determine if the high speed stop is properly adjusted.

If you discover that you have broken teeth or for any other reason you want to remove the quadrant then is the time to remove the drive belt (which is most easily done set at high speed) - this is when the belt tension is the least).

Thanks, Dusty & JPG40504.

I have the feeling (unfortunately) that I have a 'boogered' shaft, and probably a loose/broken spring and teeth which engage the speed indicating ring. I did loosen the set screw, and could rotate the dial, but couldn't pull off the dial. Clearly, I didn't loosen it enough (though I'm concerned that if I totally remove the set screw, I'll never be able to put it back in!)

Maybe if I'm unable to fix it, it's an excuse to get that PowerPro upgrade!

I'd recommend that you completely remove the set screw and do what is necessary to remove the Dial. If it is not working as is, this will have to be done eventually anyhow. If the shaft is boogered, the dial will be difficult to pull off but there is no other way.
