Content-Type: text/plain; charset="iso-8859-1"
In addition to other things mentioned....
Do a test assembly of just the crank and its one trapped bearing in the case
half. When you're sure you have the bearing properly seated in the case
(dowel in bearing's dowel hole) take a *sharp* pencil and make light lines
on the back of the bearing where the bearing meets the case halves.
Remove the crank and do a similar dry fit of the other non-split bearings in
the case half, marking each of them with a pencil as above.
Having those marks will be a big help in lining things up when you're
struggling with a heavy crank/rod assembly, trying to get the thing properly
seated in the case half. As a test to make sure you've got all the bearings
seated properly, take the remaining spilt bearing and put it in place on the
exposed journal; the bearing should sit "flat" against the case and not
"rock" back and forth (even a little) across the journal. If it does rock,
you don't have things seated properly!
