Crankshaft Connecting Rod Journal Diameter
- Measure each of the crankshaft connecting rod journal diameters in at least two directions, at each end of the journal.
- The difference in the measurements from one end to the other is the taper.
- The difference in measurements perpendicular to each other is the out of round.
- If the diameter, taper, or out of round measurement is out of specification, install new parts as necessary. Refer to ENGINE for the procedure.
