When your International Harvester tractor starts knocking at idle or you’re noticing oil pressure dropping off, worn main bearings are often the culprit. These bearings sit at the heart of your engine, keeping that crankshaft running smooth and protecting your engine block from expensive damage. This .020 oversize bearing set gets your engine back to running strong and reliable for years to come.
What You’re Getting
- Complete main bearing set sized .020 oversize for rebuilt crankshafts
- Quality materials that resist fatigue under the constant loads these engines face
- Proper clearances engineered to maintain oil pressure and reduce wear
- Direct replacement for worn original bearings during engine rebuild
Built for Real Farm Work
International Harvester tractors are known for their durability and these main bearings are built to match that reputation. Whether you’re running a utility tractor for loader work, a row-crop machine for field operations, or an older workhorse that’s been in the family for decades, these bearings handle the constant vibration and loads that come with real farm work.
Made to Last
Engine bearings take some of the hardest punishment in your tractor, especially during heavy pulling, PTO work, or long days in the field. These bearings use quality bearing materials that maintain proper oil clearances even under the temperature swings and contamination that agricultural engines face.
Installation Notes
Main bearing replacement requires complete engine disassembly and is typically a job for experienced mechanics or engine rebuilders. It’s the perfect time to have your crankshaft checked and machined if needed, since these .020 bearings are designed for cranks that have been turned .020 undersize. Always check bearing clearances with plastigauge before final assembly.
