I was DEFINITELY overthinking it. I figured there had to be something else to it, because I ordered the 6B versus the 6A and of course the threading is different!Rando wrote:Three set screws? Your spindle motor rotating parts should look like this:
You remove the collet nut and collet insert from the rotating part of the spindle. The threads specified on the Musclechuck must match those on the end, as shown in the picture. All you do is put the collet nut and collet insert away in a drawer, and screw the musclechuck onto those threads. Tighten, period, you're done. If you are thinking it's more than that, um, well, you're overthinking it.
There might be three set screws on the bottom face, but no, you only remove those to service the bearings. The ONLY things you should need to remove for the musclechuck are the collet nut and collet insert, unless the business-end of your spindle is one heck of a lot different than any spindle I've come across! I suppose I'll let you post a photo to show what you mean...

Thanks for the pic, I am a visual learner and it helped tremendously.
Have a great day!
