Bearing Selection

There are 3 methods to determine the correct replacement bearing size.

• Connecting Rod Bearing Grade Chart Method uses production markings on the crankshaft and the connecting rod to determine original bearing size.
• Micrometer method uses measurements of the crankshaft rod bearing journal and the connecting rod large end bore to determine the correct bearing size.
• Plastic gauging method is a way to verify the bearing clearance once the bearings are installed.
