REMARKS
REMOVAL
2. Main
numbers
1, 2, 3,
4, 5 and 6.
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.
