Description
When you’ve got low oil pressure or hear that telltale knock from your Cummins diesel, worn main bearings are usually the culprit. This bearing kit gives you everything you need for a quality rebuild when your crankshaft has been turned 1.0mm undersize – a common machine shop practice to clean up wear and restore proper bearing clearances.
What You’re Getting
- Complete set of main bearings sized exactly 1.0mm smaller to fit your machined crankshaft
- Proper clearances restore oil pressure and eliminate that expensive engine knock
- Quality construction that handles the loads and heat cycles of diesel operation
- Direct replacement when your crank has been professionally turned undersize
Built for Real Farm Work
This bearing set fits Cummins 6-590, 6T-590, and 6TA-590 CDC-B series engines – the reliable 6-cylinder diesels that powered many agricultural and industrial machines through years of heavy service. These engines were built to work hard, and when it’s time for a rebuild, you want bearings that’ll give you the same durability.
Made to Last
Diesel engines create serious pressures and temperatures that standard bearings just can’t handle. These main bearings use materials and coatings specifically designed for diesel service, with the strength to support your crankshaft under load and the oil retention properties that keep everything lubricated properly.
Good to Know
This is for engines where the crankshaft journals have been machined 1.0mm undersize – standard practice when rebuilding worn engines. Always verify your crank measurements before ordering, and make sure you’ve got the matching rod bearings if you’re doing a complete bottom-end rebuild. Fresh bearings deserve clean oil and a new filter.
