No 1406 kits? Oh well the endbells on the front are all the same right? Guess I will just have a rotor for sale unless someone has a front endbell and bearing(3.2 mm) they would be willing to let go. My buddy has a rig dyin for this 4600 1406 four pole.
AFAIK, the bearings are the same on the 5MM and 3.2MM shaft models. The shaft is 5MM where it goes through the bearings.
