Clevite Caterpillar D318 333 6 Cyl Main Bearing Set

When you're rebuilding the bottom end of your Caterpillar D318 6-cylinder engine, getting the main bearings right is crucial for proper crankshaft support and oil pressure. This set from Clevite is built to handle the demands of these industrial engines.

Clevite uses a tri-metal construction for these bearings, which is a popular choice for heavy-duty applications because it offers a good balance of strength and wear resistance. The 0.010 inch undersize means these are intended for crankshafts that have been machined down by that amount to correct for wear or runout. Proper installation, including ensuring the crankshaft journals are clean and within the specified tolerance, is key to getting the most out of these bearings.
