Not a model though fairly small. A 2hp 1000rpm engine-driven direct-coupled
genset. The flywheel and dynamo drive flange each have pins (3/4" and 1 1/4"
respectively) bolted to them which engage in holes in the other and there is
1/4" leather sandwiched between the flanges.
Its obviously been run both out of alignment and long after it should have
been sorted. The pins are a very odd shape and the holes are sort of
elliptical. I've worked out how to set up and re-machine but am unsure of
how much clearance to leave twixt holes and pins. How does say 0.002" sound?

thanks for any thoughts
