Speed Control Dial rattle

On putting back the speed changer and turning on, the speed control dial rattles at lower speeds, between SLOW and Saw/Jointer setting. The rattle goes away beyond Saw/Jointer setting. Seems like the SPRING does not help much in preventing the rattle cause of the grove on 'speed control dial' between SLOW and Saw/Jointer setting.

I do not recall hearing the rattle previously. Am I missing something ? This is the first time I removed the speed changer after I got the used SS couple of months ago.

Thanks

There is a small spring that goes behind the dial called the dial spring

number 83 on this diagram

that keeps it from rattling.

Page b6 of this pdf shows a better diagram.

Thanks Mike. The dial spring, #83, is in place. The speed control dial is the one rattling. I have the spring under it and it is set properly and it does seem to have good amount of tension. Wondering if there is any other thing I need to pay attention to or do differently or change the spring.

Thanks,

Sometimes the little finger-knob on the speed-control "big red" knob will be loose. It can loosen over time and be a rattler. But if you buy a new one and see it staked very tight, you notice the difference.

Check for #73 in Mike's post.

You can use a center punch to tighten the existing finger knob on the "big red" knob as many finger knobs will become loose and rattle. I allow for a slight movement of the little knob when tighten this knob. A little should do the trick.
