Tadek,
The shells are made within a certain tolerance band, which means that
there are very small differences in size. The same when you have a
crankshaft reground, these are also ground within a certain tolerance
band. If you have the smallest journal of the crankshaft with the
largest diameter bearing, the play in that position will be slightly
larger than in the rest. That is why you use the plastigauge, to find
out whitch shells should be combined with which journal to get an as
even as possible play in each bearing/journal.
