1. Remove the 4 housing bolts and pull the front housing
off OVER the shaft. Never pull the rear housing off first!!!!
If it is jammed or rusted use some WD-40 on the shaft and alternately
tap the mounting wings with a hammer while applying pressure
to the shaft with your thumb so that the stator and it's delicate
wiring harness is kept in place. NOTE: If the shaft is scored-up
badly you may have to sand the shaft down to it's original 17mm
size to get the front housing off.
2. Now grab the exposed rotor core shaft and pull it out
WHILE holding down the stator ring with your index
