Thanks for all the suggestions, have kind of messed up the kevlar so realy regretting that i dissasembed this thing.

Tried wrapping it in paper, tape, feeler gauge and everything else i could put my hand on that fit inside the hole, without any success. At this point my best bet is to contact castle for repair.

Btw i really dont understand why they are using so strange srews, like those holding the rear end bell, today i was visiting several hardware shops and i couldent find a single fitting wrench.
Its torx but no torx wrech is fitting
