Compare the two values obtained
through measurement of connecting rod
bearing inside diameter with the outside
diameters of the crankshaft pins to
determine the oil clearance.
If the clearance deviates from the
specified range, polish the crankshaft
journals and pins ground and install undersized bearings.
Connecting rod bearing clearance (Method 2 : with plastic gauge )
Assemble the crankshaft on the cylinder block and put the plastic gauge on the journal and
pin of crankshaft and then after assembling bearing cap, tighten the bolts at the specific
torque. Again after disassembling the bearing cap by removing the bolts, take out the flatted
plastic gauge and measure the width of plastic gauge by means of plastic gauge measuring
scale. This is the oil clearance.
3) Bearing spread and crush
Inspection
Check to see that the bearing requires
a considerable amount of finger
pressure at re-assembly operation.
