Nips , Buy 2 bolts ( 5mm x .8 pitch x 60mm long ) ... they will screw into the stator, then get a piece of plate  80mm in dia approx  &  10mm  thick  drill a 12mm hole in the centre then weld a M 10 nut over the top of the hole - grind a point onto the bolt  ( 50mm long )  that goes thru the M 10 -  measure the distance the 2 stator threads are apart and transfer that onto your plate drilling the holes @ 6mm dia ...... now you have a puller
