What is tri-metal construction?

Tri-metal construction refers to a bearing design with three distinct layers. It typically includes a steel backing for strength, a copper-lead alloy for load capacity, and a thin babbitt overlay for reduced friction and better embeddability. This design is common in heavy-duty engine bearings.

What is the importance of oil clearance for main bearings?

Proper oil clearance is critical for main bearings to function correctly. It allows a thin film of oil to form between the bearing and the crankshaft journal, preventing metal-to-metal contact. This film reduces friction and wear, dissipates heat, and cushions against shock loads, all contributing to engine longevity.

Does this bearing set come with all necessary hardware for installation?

This listing is for the main bearing set only. It includes the main bearings themselves. It does not typically include crankshaft bolts, seals, or other installation hardware, which should be sourced separately if needed.

Product Details

This Clevite main bearing set, part number MS2324P20, is built with a tri-metal construction. This means it has three distinct layers: a steel backing for strength, a copper-lead alloy for load carrying, and a thin overlay of babbitt for reduced friction and improved embeddability. This combination is key to handling the heavy loads and high temperatures found in large displacement engines like the Caterpillar 3406, 3408, and 3412. These bearings are designed to maintain proper oil clearance, which is crucial for engine longevity and performance.

When you're rebuilding a large engine, getting the main bearings right is essential. Clevite has a long history of producing well-built engine components, and this set is no exception. The tri-metal design helps distribute stress evenly across the bearing surface, reducing wear and preventing premature failure. Proper installation, ensuring the crankshaft journals are clean and within spec, is vital for these bearings to perform as intended. This set is a solid option for anyone looking to restore or rebuild their Caterpillar engine with reliable internal components.
