How do I get the BBSHD stator out of its casing?

I was being stupid... I tested the motor without assembly its entire body together, basically just the stator and the shaft, plus I forgot to put all the screws that supposed to hold the stator in place....so apparently when I pressed the throttle the stator moved for half an inch away from its original spot so I can't put everything back together anymore. I tried to insert screws around the holes of the stator and turned it back to the old spot but it's impossible, I think it's pressed-fit into the case. Does anyone have any tips to get it out?
I tried to google out the way to fully disassemble the bbshd but they always skip the part of getting the stator out on camera, I think it must be a very hard job to do. For the rotor shaft, I don't think it's that hard to get it out 'cause I have seen people try getting it out before.
