[Mg-mmm] PB Crank Flange Removal.

[Clive Sherriff]

There is a bit of a problem with these flanges, in that the flange can in 
effect fret weld itself to the taper.  An hydraulic puller and a damn sharp 
tap (=clout!) with a 4 lb hammer might do the trick.  I've had this problem 
a few times on Pheonix and other close tolerance taper shafts.  Have you 
tried talking to John at Phx. about this?
