(3) Compare the two values obtained
through measurement of bearing
inside diameter with the outside
diameters of crankshaft journals and
pins to determine the oil clearance.
(4) If the clearance deviates from the
specified range, have the crankshaft
journals and pins ground and install
undersize bearings.

3) Inspection of bearing spread and crush
(1) Check to see that the bearing
requires a considerable amount of
finger pressure at reassembly opera-
tion.
(2) With a bearing crush aligner, mea-
sure bearing crush.
