Ouch! wasn't expecting $45. Know of anything aftermarket? I don't need it to last another 50 years.

So use a M5 belt.

Maybe this will help with cam follower assembly.

And this.

Yes, that really helped a lot. I am not sure what I did wrong, but I flipped it over again following your directions and all is right in the world again. The follower is not binding on the side anymore, and I have the "skinny" side facing the increasing diameter, but I still seem to have to rotate the eccentric opposite what you recommend to not have it touch. I am going to get the new belts anyway. She deserves it.

Thanks again JPG.

Is the control knob shaft tight or is there end play? I wonder about he duplicate pin holes???

Nope, no end play to speak of, no wobble, everything is tight. Duplicate pin holes?

Maybe different thread, but previous posts mentioned more than one pin hole.

I don't remember any alternate pin holes on my speed cam. I did have an alternate key way on the sheave which I thought was odd. It is all back together and operating really well, so I better not push my luck. I think I will try to find a new eccentric end nut and safety washer. The nut is not a very tight fit to the threads and I question if it is original. Maybe that is why the square nut was being used as well?

By M5 belt you mean the thinner version used by the Mark V that I read will work on the Mark VII, correct?

here is a link to the thread about 2 roll pin holes thru the MKVII speed cam shaft.

Thanks for the link. Interesting, I took a pic and can only see the one roll pin. I suppose it could have an alternate drilling under the plastic, but I'm not going to mess with that. I would likely crack it and create a new problem.
