One New Aftermarket Replacement Main Bearing (.030 In / 0.75 mm Oversize) for Caterpillar (Cat) D353 / G353 Engines

This aftermarket replacement engine main bearing is an oversize unit ground to +0.030 inch (0.75 mm) for use during engine rebuilds where the crankshaft has been reground to the matching undersize. It fits the Caterpillar D353 and G353 inline 6-cylinder heavy-duty diesel engine -- a large-displacement workhorse used in heavy construction, mining, marine generator sets, oilfield pumps, and stationary power applications. The D353 uses seven main bearing caps supporting a forged steel crankshaft; always verify your engine serial number and crankshaft grind specification before ordering an oversize bearing.
