When I first got my CNC mill working I had to pull the pulley for some reason (I don't remember what) so looked at it, measured one hole size, and the distance between two holes, and cut this lovely tool that fit in the pulley with fingers about 0.1mm smaller than the holes, so I could put it in with a 2m long breaker bar on it, then a second breaker bar on the (31mm?) nut, and pop the nut loose.
Except I didn't actually COUNT the number of holes. I figured it would be six holes. There are seven, in a 1200's pulley.
So I made the tool and... nope. I had to remake it for 7 holes.
But then it worked great.
Now I have an A14 with a pulley I got somewhere else (hence the missing index mark) and it has no holes in it to index on. If I had to do this a lot I'd make a clamp-on tool that fits in the v belt flange and clamps tightly enough to let me shift the crank main nut.
