When your engine starts knocking or you're hearing unusual sounds from the bottom end, it's time to look at those main bearings. These are the critical components that keep your crankshaft properly positioned and supported as it spins thousands of times every minute. A worn set of main bearings won't just make noise—they'll eventually lead to catastrophic engine damage that'll cost you a lot more than this repair. What You're Getting Complete set of standard-size main bearings designed specifically for the Cummins 4B engine Precision-manufactured to OEM specifications for proper clearances and oil flow High-quality bearing material that handles the heat and pressure of diesel operation Direct replacement for worn original bearings—no machine work required when crankshaft is in good condition Set includes all bearings needed for a complete bottom-end rebuild Built for Real Farm Work This bearing set is engineered for the Cummins 4B diesel engine found in Case IH Maxxum 5120 and 5220 tractors. These mid-range utility tractors handle everything from loader work to field operations, and that Cummins four-cylinder provides reliable power for hay operations, livestock chores, and general farm work where you need dependable performance day after day. Made to Last Main bearings are one of the hardest-working parts in your engine, supporting the full weight and rotational forces of the crankshaft under tremendous pressure and heat. These bearings use modern materials and coatings designed to handle the demands of agricultural diesel engines, providing the oil clearances and load capacity your Cummins 4B needs for long service life. Installation Notes Before installing new main bearings, have your crankshaft checked for wear and proper dimensions—worn journals will destroy new bearings quickly. Clean everything thoroughly and follow proper torque specifications when reassembling. Check your connecting rod bearings at the same time since they're likely due for replacement too. A good machine shop can measure everything and ensure you get maximum life from your rebuild.
