6.2.7. Crankshaft bearing and con- rod bearing
1) Visual check
Visually check the crankshaft bearing and the connecting rod bearing for scores, uneven
wear or damage.
2) Oil clearance between crankshaft and bearing.
•
Main bearing clearance
Install the main bearing in the
cylinder block, tighten the bearing
cap to specified torque, then
measure the inside diameter.
Compare the two values obtained
through measurement of the main bearing inside diameter with the outside diameter of the
crankshaft journal to determine the oil clearance.
•
Connecting rod bearing clearance
(Method 1)
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 diameter.
