Crankshaft Main Bearing: Testing and Inspection

Using suitable measurement tools, check the main bearings for the following dimensions:

- Main bearing thrust washers, axial clearance:

^ New: 0.07-0.23 mm (0.0027-0.0090 inch).
^ Wear limit: 0.30 mm (0.0118).

- Check radial clearance with Plastigage:

^ New: 0.02-0.06 mm (0.0008-0.0023 inch).
^ Wear limit: 0.10 mm (0.0039 inch).

NOTE: Do not rotate the crankshaft when checking the radial clearance.
