NOTE
The upper and lower main bearing shells are not alike: the upper bearing shell is
grooved and drilled for lubrication - the lower bearing shell is not. Be sure to install
the grooved and drilled bearing shells in the cylinder block and the plain bearing
shells in the bearing caps, otherwise the oil flow to the bearings and to the upper
end of the connecting rods will be blocked off. Used bearing shells must be
reinstalled on the same journal from which they were removed.
3. Install.
Start the plain
end of the
bearing shell
around the
crankshaft
journal so that,
when the bear-
ing is in place,
the tang will
fit into the
groove in the
bearing support.
