Mamiya Sekor sx 135mm 2.8 assembly

So, I just got a brand new Mamiya Sekor sx 135mm f2.8.

I was attempting to modify the aperture pin as I do many other m42 lenses, but after taking this one apart I quickly learned I have no idea how to re assemble it. I can't find anything online in terms of a service manual, does anyone know of a link they could share as to re-assembly ? When I put the aperture ring back over top the lens I can only get the aperture to change by rotating the entire end piece, aperture ring and mounting ring, as opposed to just the aperture control ring itself. I know this lens has another little pin in it I am wondering that could have something to do with it but I am not sure. Maybe I am missing a piece?

I will add photos soon to show where I am. Thanks in advance.
