Clevite Cummins KT KTA Series 6 Cyl Main Bearing Set

When you're rebuilding the bottom end of your Cummins KTA engine, getting the main bearings right is crucial for long-term reliability. This set from Clevite is built to handle the demands of those powerful 6-cylinder engines, ensuring your crankshaft spins true and oil pressure stays where it needs to be. Proper main bearings are the foundation for a healthy engine, preventing excessive wear and maintaining the critical clearances that allow your engine to perform as it should.

Clevite uses a tri-metal construction in these bearings, which is a well-known standard for heavy-duty applications. This means you get a strong, durable bearing that can withstand the high loads and temperatures common in Cummins engines. The 0.010 inch undersize specification on this particular set (indicated by the 'P10' in the part number) is important to note. This means the bearings are designed to be used when the crankshaft journals have been machined down by 0.010 inches to correct for wear or out-of-round conditions. Using the correct undersize bearing ensures you achieve the proper oil clearance, which is vital for lubrication and preventing bearing failure. This set is designed to fit right and perform reliably, giving you confidence in your engine rebuild.

When installing these bearings, always refer to the manufacturer's service manual for the correct torque specifications and assembly procedures. Ensuring the crankshaft journals are clean and free of debris before installation is also critical. This set is a solid option for anyone undertaking a serious rebuild on their Cummins KTA series engine, aiming for a durable and reliable outcome.
