Connecting rod bearing clearance
Install the connecting rod bearing in the
connecting rod bearing cap, tighten the
connecting rod cap bolts to the specified
torque, then measure the inside diame-
ter.
Compare the two values obtained
through measurement of connecting
rod bearing inside diameter with the
outside diameters of crankshaft pins to
determine the oil clearance.
•
If the clearance deviates from the
specified range, have the crankshaft
journals and pins ground and install
undersize bearings.

Connecting rod bearing clearance
(Method 2 : with plastic gauge )
Assemble the crankshaft on the cylinder block and put the plastic gauge on 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 plas-
tic 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 reassembly operation.
