Hmmm. Okay, I have the manual, but I don't see how you
did the calculation. I see crankpin diameter, bearing
internal diameter, and bearing diametrical clearance,
but not something that tells me the internal diameter of
the rod (without the bearing in place). I seem to be
missing something . . . ?

I have a micrometer set, but unfortunately the block and
crankshaft are already at the machinists, so I couldn't
take the measurement. I was trying to figure out what
size bearing was used last time. I suspect they are
already undersized. In any case, I took rods and the head
and everything else over to the machinists today. So, with
his help I should be able to get it all sorted out.
Thanks again.
