Main Bearing Journal Diameter (Crankshaft Removed)
WARNING: This page is about a different variant/trim than selected.
CAUTION:
If the engine encounters a catastrophic failure, the engine oil cooler and lines must be replaced or damage to the new engine or components could result.
Crankshaft removed from the cylinder block.
Clean the oil off the main bearing journal.
Determine the maximum diameter of the journal with a micrometer. Measure at two locations 90° apart at each end of the journal.
The maximum allowable taper is 0.008 mm (0.0003 inch). The maximum out-of-round is 0.005 mm (0.0002 inch). Compare the measured diameter with the journal diameter specification (Main Bearing Fitting Chart). Select inserts required to obtain the specified bearing-to-journal clearance.
