d. Measure the crankshaft journal bearing
inside diameter "b" of each crankshaft jour-
nal bearing at two places.
e. If crankshaft journal bearing inside diame-

ter is "54.98", then the journal oil clearance
is:
Journal oil clearance:

If the oil clearance is out of specification,
select replacement bearings.
