NOTE
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 bearing cap before removing another bearing cap.
