These pics are actually from JV in Florida when he did the Centa conversion. I actually have his old Harley style compensator along with the Mercedes rubber flex coupling and stub shaft with the flywheel bolt pattern. I took it apart and it was clear what goes bad on the early units. I did a picture thing on that some time ago.
So to answer your question about close ups, I've got nut'n...
Maybe Phil has taken some close up pics as he's been working in this area with his prototype urethane inserts.
I would have just linked you back to JV's post, but he's removed or moved his pics and the properties links are no longer valid for his pics. I try to copy everything I can quickly so if they go bye bye I've got them or can share them later.
