moving in the bearing
caps or bearing sup-
ports.
4. Measure the thickness
of the bearing shells
at point "C", 90from
the parting line.
Tool J5347-01, placed
between the bearing
shell and a micrometer,
will give an accurate
measurement. The
bearing shell thick-
ness will be the total
thickness of the steel
ball in the tool and
the bearing shell,
less the diameter of
the ball. This is the
only practical method
for measuring the
bearing thickness,
unless a special micro-
meter is available for
this purpose. The
minimum thickness of
a worn standard main
bearing shell is
.1540 inch (0.3912 cm)
and, if any of the
bearing shells are
thinner than this
dimension, replace all
of the bearing shells.
A new standard bearing
shell has a thickness
of .1545 to .1552 inch
(0.3924 to 0.3942 cm).
