There’s nothing more frustrating than pulling your tractor out for spring fieldwork only to hear that telltale knocking sound from the engine. When your main bearings are worn out, you’re looking at serious engine damage if you keep running. This main bearing kit gets you back on solid ground with bearings sized 0.010″ over standard to compensate for wear on your crankshaft journals.
What You’re Getting
- Precision-sized bearings at 0.010″ oversize to restore proper clearances on worn cranks
- Complete set of main bearings for your International Harvester engine rebuild
- Quality aftermarket construction that meets or exceeds original specifications
- Direct replacement for worn factory bearings without modifications
Built for Real Farm Work
This kit fits a range of International Harvester engines found in tractors from the Super A series through various utility and row-crop models. Whether you’re running a smaller utility tractor for chores around the farm or a larger row-crop machine for serious field work, proper main bearing clearance is critical for engine longevity and oil pressure.
Made to Last
These TISCO main bearings are manufactured to handle the constant stress and vibration that farm engines endure. The 0.010″ oversize dimension allows your machinist to clean up wear on the crankshaft journals while restoring factory oil clearances. Quality materials and construction mean these bearings will give you years of reliable service.
Installation Notes
This is an oversize bearing set, so your crankshaft will need machine work before installation. Take your crank to a qualified machine shop to have the journals turned 0.010″ under standard size. Check main bearing bore alignment while you’ve got the engine apart – it’s cheap insurance against future problems.
