Description
When you’re staring at low oil pressure readings and hearing that telltale knock from deep in the engine, worn main bearings are usually the culprit. This 0.50mm oversize main bearing kit gets your 6T-830 or 6TA-830 diesel engine back to tight tolerances and proper oil pressure, restoring the power and reliability you need for long days in the field.
What You’re Getting
- Complete set of oversize bearings designed for engines with machined crankshafts
- 0.50mm larger diameter to compensate for worn journals and restore proper clearances
- Quality construction that meets OEM specifications for long-lasting performance
- All bearings needed for one complete engine rebuild in a single kit
Built for Real Farm Work
This bearing kit is designed specifically for the 6-cylinder turbocharged 6T-830 and turbocharged/aftercooled 6TA-830 diesel engines found in various Case IH tractors and equipment. These engines see hard work pulling heavy implements, running hydraulics, and powering through tough field conditions where reliability matters most.
Made to Last
Main bearings take tremendous loads and constant pressure cycling as the crankshaft spins. These bearings are manufactured to handle those demanding conditions with proper materials and construction that maintain oil film strength under load. They’re built to OEM standards so you get the durability the engine was designed for.
Good to Know
Installing oversize bearings requires having the crankshaft journals machined to accept the larger bearings – this isn’t a job for basic tools. Make sure your machine shop turns the crank to the proper 0.50mm oversize specification. While you’re rebuilding, it’s smart to check connecting rod bearings, oil pump, and other wear items that could cause problems down the road.
