Checking Clearances
CONNECTING ROD BEARING AND CRANKSHAFT JOURNAL CLEARANCE
Measure the connecting rod bore with the bearings installed and the bolts tightened to 100 Nm (73 ft. lbs.) torque.
Record the smaller diameter.
ALTERNATIVE GRADE IDENTIFICATION METHOD
Connecting Rod Journal Diameter Limits
Measure the diameter of the rod journal at the location shown. Calculate the average diameter for each side of the journal.
The clearance is the difference between the connecting rod bore (smallest diameter) and the average diameter for each side of the crankshaft journal.
If the crankshaft is within limits, replace the bearing. If the crankshaft is out of limits, grind the crankshaft to the next smaller size and use oversize rod
bearings.
