The frame counter is driven by the first turn around roller on the supply side (thickish black roller) and you have to bond the main roller body to the rubber ring at the insert-top end in order for 35 mm film to drive the frame counter. On my 220 back, I used the tiniest drop of super glue and it appears to work correctly (though I haven't shot another roll of 35 mm film since then).
I've just used two teeny tiny drops of superglue spread with a toothpick and it seems to have made a very solid connection. It's held very strongly in place and spins nice and smoothly. Still need to run a roll through but things are looking good. I wonder why Mamiya had them as separate parts where previous models didn't do that? Anyway I've put in new light seals too so the whole thing should be set for a "real" run soon! The weather in Sydney's been a bit dreary lately—great for taking photos with a camera that I can keep out of the rain under an umbrella, not so much for the RB67 which is too heavy for me to carry for more than a few minutes
