I'm having trouble reading several dimensions on this technical drawing.
First, I don't know how big is the diameter of the marked cylinder.
M24 is a threaded hole in my opinion and that cannot say anything about the cylinder.
And what is the diameter of the rotor ? Is it 40 ? if yes then why they didn't put any diamater mark next to the number 40 ?
And I cannot find out the angle of the central key relative to slots?
