The basic purpose of the Chevrolet C1500 Rod Bearing is to maintain the free rotation of the crankshaft by forming a thin film of pressurized oil that prevents metal components from grinding against each other. Positioned between the connecting rod and journal, each Rod Bearing has precise oil clearances of approximately two to four thousandths of an inch and a small crush fit so that it locks solidly into its saddle once the cap bolts are torqued. Oil pumped through block passages is supplied to the bearing grooves to suspend the crank on a liquid to reduce heat and wear. Over the generations of the Chevrolet pickup, two styles dominate. The bi-metal Rod Bearing combines an aluminum-silicon alloy with a stiff steel case providing excellent seizure resistance for everyday C1500 duty. Higher stress applications depend on the tri-metal Rod Bearing design, where a copper layer and a soft lead-tin overlay provide added strength, fatigue resistance and capability to embed grit that might scar journals. Although both Rod Bearing styles have the same outer dimensions, the tri-metal design has a higher tolerance for heavy loads and higher engine speeds, making it popular with performance-minded Chevrolet owners who drive their C1500 harder. Selecting the right bearing size after any crank regrind will ensure proper clearance and long engine life.
