CATERPILLAR-3003-CONROD-BEARING-SET-STD

153-5520 is a standard-size connecting rod bearing set for the Caterpillar 3003, supplying the shell bearings that sit between the rod's big end and the crankshaft journal. Standard size fits an unmachined, factory-diameter crank journal — if the crank has previously been reground, one of the corresponding undersize bearing sets is needed instead.
