Flux Warp motor disassembly

[herK]

Hello!

I bought a used Flux Warp motor and its whizing at loading. I only can hope only the bearings need to be changed.
Any ideas how to open the motor? I found 3 screws at the back plate, and 2 worm screw in the front plate. I screwed all but dont know how to continue, never opened brushless motor at all.

Thanks for your help!!!
