9.2.7. Crank shaft bearing and connection rod bearing
1) Visual check
Visually check the crankshaft bearing and
connecting rod bearing for scores, uneven
wear or damage.
2) Oil clearance between crankshaft and bearing.
•
Main bearing clearance (Method 1)
Install the main bearing in the cylinder
block, tighten the bearing cap to speci-
fied torque, then measure the inside
diameter.
Compare the two values obtained
through measurement of main bearing
inside diameter with the outside diame-
ters of crankshaft journals to determine
the oil clearance.
