Description

When your engine starts knocking or showing signs of bearing wear, it’s time for more than just an oil change. This main bearing kit gives you the precision-engineered bearings you need to restore proper clearances and get your Case IH tractor back to reliable operation. The 0.75mm oversize means you can machine the crankshaft slightly and still maintain proper oil clearances.

What You’re Getting

Complete main bearing set sized at 0.75mm oversize for proper crankshaft clearance
Precision-manufactured bearings that meet or exceed original equipment specifications
Durable tri-metal construction designed to handle the demands of turbocharged engines
Direct replacement for worn bearings in 6T-830 and 6TA-830 diesel engines

Built for Heavy-Duty Work

These bearings are specifically designed for the 6T-830 6-cylinder turbocharged and 6TA-830 6-cylinder turbocharged/aftercooled diesel engines found in Case IH tractors and combines. These powerplants are workhorses that handle everything from heavy tillage to harvest, and they need bearings that can keep up with the demands of commercial farming operations.

Made to Last

Main bearings take a beating in turbocharged engines, dealing with higher pressures and temperatures than naturally aspirated motors. These bearings feature the tri-metal construction and precision tolerances needed to handle the extra stress while maintaining proper oil flow and pressure throughout the engine.

Good to Know

This is typically an engine-out job that requires machining the crankshaft journals to 0.75mm oversize. Make sure to check all main journals for proper sizing and roundness before installation. It’s also a good time to inspect the connecting rod bearings and replace them if needed—having the engine apart is the perfect opportunity for a complete bottom-end rebuild.
