One New Aftermarket Replacement Connecting Rod Bearing - 0.25mm Oversize for Caterpillar (Cat) Engines
This 0.25mm oversize connecting rod (conrod) bearing is a precision engine component used in Caterpillar's large-displacement 3500 and 5000 series diesel engines. It fits the crankshaft journal of the connecting rod, maintaining the critical oil film between the rod and crankshaft to prevent metal-to-metal contact under load. This is a 0.25mm undersize journal bearing - confirm your crankshaft grind specification before ordering.
