Rod Bearings

WARNING: This page is about a different car, the 2002 Mazda B3000 and 2001 Mazda B3000. However, it is still accessible from the selected car via links, so may be relevant.

Using Plastigage method, check rod bearing clearance. If proper oil clearance cannot be obtained with standard bearings, try a combination of oversize bearings. DO NOT use any bearing combinations other than those listed. See OVERSIZE MAIN & ROD BEARING COMBINATIONS 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.
