Description
When your trusty Cummins engine starts knocking or the oil pressure drops, it’s often time for a main bearing rebuild. This undersized bearing set gives your worn crankshaft journals a second lease on life, letting you machine them 0.75mm undersize and get back to reliable operation without the expense of a complete overhaul.
What You’re Getting
- Complete main bearing kit with all shells needed for one Cummins 6-cylinder engine
- 0.75mm undersized bearings that match machined crankshaft journals perfectly
- Quality construction that handles the demands of diesel operation and heavy loads
- Direct replacement for worn standard bearings – no guesswork on fitment
Built for Real Farm Work
This bearing set is engineered specifically for the Cummins 6-590, 6T-590, and 6TA-590 CDC-B series engines found in Case and other agricultural equipment. These are the workhorses that power combines, tractors, and other heavy-duty machines through long harvest days and tough field conditions.
Made to Last
Diesel engines run hard and these bearings are built to match that intensity. The bearing material and construction handle the pressure, heat, and vibration that come with agricultural work, giving you the durability you need to keep your equipment running season after season.
Good to Know
This is an undersized bearing kit, so your crankshaft will need to be machined 0.75mm undersize before installation. It’s a job for your engine shop, but once it’s done, you’ll have an engine that runs like new. Make sure to check your connecting rod bearings and other wear items while you’ve got everything apart.
