When your International Harvester’s engine starts knocking or you notice oil pressure dropping, it’s often telling you the crankshaft bearings are getting worn. During a rebuild or major overhaul, you’ll likely need undersized bearings if the crankshaft has been turned. This .020 undersized main bearing set gives you a proper fit when your crank journals have been machined down to restore their surface.
What You’re Getting
- Complete main bearing set sized .020 under standard for properly machined crankshafts
- Precision-manufactured bearings that restore proper oil clearances and pressure
- Durable construction designed to handle the demanding loads of farm work
- Quality materials that provide reliable lubrication and heat dissipation
Built for Real Farm Work
This bearing set fits International Harvester tractors that need main bearing replacement during engine rebuilds. Whether you’re overhauling a utility tractor that’s been running the farm for decades or rebuilding a larger row-crop machine, these bearings are engineered to handle the constant loads and varying RPMs that come with field work, loader operation, and PTO-driven implements.
Made to Last
Engine rebuilds aren’t something you want to do twice, so these bearings are built with the same quality standards as original equipment. The bearing material provides excellent wear resistance and maintains proper oil film thickness even under heavy loads. They’re designed to give you years of reliable service when properly installed with correct clearances.
Installation Notes
These are .020 undersized bearings, so make sure your crankshaft has been properly machined to the correct undersize before installation. Always check bearing clearances with Plastigage and verify oil pressure after installation. If you’re doing the work yourself, take your time with torque specs – main bearing cap bolts are critical and need to be tightened to specification in the proper sequence.
