      I am out of town right now but will pull the toasted motor as soon as I get back into the shop, and check the flange and shaft dimensions.  Some of the posts on this subject from 2009 seem to be referring to belt drive units that have a smaller than normal (24mm) shaft.  My mill has a 6 speed geared head.  The truth is out their...and I will find it as soon as I can.

      Check the shaft size it might not be standard for the sized motor.

      Be well,
