Safety Handweehls Deckel FP

I like to disassembly the Safety Handweehl's of a Deckel FP2, does someone ever made that for whatever reason?
I realy need some expert help, it seems the hardened Pin's kept extreme tight in place. What options do i have to get it apart ??

As you guys can see, one is other than the other; it meens that the bushing from the bigger weehl is one part with the winder/ crank... but inside they may look the same!?



Thanks for any help!!! :skep:
