It would be impossible on at least one of the main bearings, which are
one-piece cylinder type bearings. I usually take that piece in, since the
measurement is so critical. I could do it with telescoping gauges, but
there's always room for error. You want a good inside micrometer on it. The
good thing about telescoping gauges is that the same instrument is used to
measure the gauge that is used to measure the journal, so even if it's out
of calibration, the measurement will be right. But it's just easier and
safer to have it measured at a machine shop.
