Crankshaft And Main Bearings
WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Main bearing caps are numbered 1-5. If crankshaft bearing journal dimensions are not within specification, grind journals or replace crankshaft and bearings as necessary. Using bore gauge, check main bearing bore for concentricity and alignment. Replace engine block if crankshaft bearing bores are out of specification. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS.
