Rod Bearings

Using Plastigage method, check rod bearing clearance. If proper oil clearance cannot be obtained with standard bearings, try a combination of undersize bearings. DO NOT use any bearing combinations other than those listed. See UNDERSIZE MAIN & ROD BEARING COMBINATIONS table. To check connecting rod specifications, see CONNECTING RODS table.
If use of bearing combinations does not bring clearance within specification, machine or replace crankshaft as necessary. Always replace bearings in pairs. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS.
