Martin,
From what you've written, just replace the shells and don't worry about
measuring
the journals. You said the old bearings looked good with no scoring,
that's a good
indication the cranks in good condition. If you want to make a big job of
it, then go
ahead and pull the crank and do your stuff. But it doesn't sound to me as
if it's
necessary. Oh, do measure the crank end float for fitting new thrust
washers.
