Clevite Caterpillar D339 4 Cyl D342 6 Cyl Con Rod Bearing Set

These Clevite connecting rod bearings are built with an aluminum alloy overlay that’s 25% harder than standard materials. This improved hardness helps them resist wear and fatigue, especially in engines that see a lot of work. They are designed to fit Caterpillar D339 4-cylinder and D342 6-cylinder engines, providing a solid option for rebuilding or replacing worn bearings.

The aluminum alloy construction is a key feature here, offering a good balance of strength and conformability to the crankshaft journal. This helps ensure proper oil film formation, which is critical for reducing friction and heat buildup. When you're putting an engine back together, getting the bearing surfaces right is crucial for long-term reliability, and these Clevite bearings are made to handle that job.
