After a bit rounded 'teeth of the crown to make it look like a gen, I replaced the gasket with a thicker one. Regard the pressure of the lever, I noticed that my rep 177L allowed to wind movement with the lever closed (see the video that I put on youtube: http://www.rwgforum....my-first-pam-d/ ) . I don't know if the gen do the same thing, but I doubt is possible. If there is pressure to push the lever against the crown than the crown cannot rotate, but if the crown is free to move then I think that pressure is not so good. The crown must remain pressed against the hexagonal tube and the force against the gasket must to stop the crown. Now can say that I have not encountered problems, lever closes and opens properly. Now is not possible to wind movement when lever is closed, so the crown is locked.
