Main Bearing Journal Diameter (Crankshaft Removed)

WARNING: This page is about a different car, the 2012 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Remove the crankshaft from the cylinder block. Refer to CRANKSHAFT, REMOVAL, 3.7L .

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 (0.0004 inch.) and maximum out of round is 0.005 mm (0.002 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.

Install the crankshaft into the cylinder block. Refer to Engine/Engine Block/CRANKSHAFT - Inspection .

Check crankshaft end play.
