Crankshaft: Testing and Inspection
Journal
Connecting Rod Journal Diameter
1. Measure the crankshaft connecting rod journal diameters in at least two directions perpendicular to each other. The difference between the
measurements is the out-of-round. Verify the journal is within the wear limit specification. Undersize connecting rod bearings will need to be
installed.
Connecting Rod Journal Taper
1. Measure the crankshaft connecting rod journal diameters in two directions perpendicular to each other at each end of the connecting rod journal.
The difference in the measurements from one end to the other is the taper. Verify the measurement is within the wear limit. Undersize connecting
rod bearings will need to be installed.
Main Bearing Journal Clearance
1. Remove the crankshaft main bearing caps and crankshaft main bearing.
NOTE: Crankshaft main bearing journals must be within specification before checking journal clearance.
