NOTES
All crankshaft main bearing journals, except the rear journal, are drilled for an
oil passage. Therefore, the procedure for removing the upper bearing shells
with the crankshaft in place is somewhat different on the drilled journals than
on the rear journal.
If shims are used between the oil pump and the main bearing caps, save the
shims so that they may be reinstalled in exactly the same location.
Remove one main bearing cap at a time and inspect the bearing shells as
outlined under inspection. Reinstall each bearing shell and bear- ing cap
before removing another bearing cap.
