Tom,


I asked the tool and die instructor to mike and machine if necessary a new shaft to press in for the 1510 originally when I left it with him.  When I returned to pick up the motor housing/rotor his assessment was the rear rotor surface needed to be sleeved. All I know is it did the trick, no more chatter after hours of test running it.


When you say the shaft is tapered, are you stating from wear, or factory taper?
Russ,
Try installing the rotor backwards.  The rear bearing surface is slightly under the press-fit diameter.  And the front bearing surface is slightly under the rear by a few thou.
