When your International Harvester engine is knocking or showing low oil pressure, worn main bearings are usually the culprit. Getting to them means splitting the tractor or pulling the engine, so when you’re that deep into things, you want bearings that’ll last. This .010″ oversize main bearing kit gets your rebuilt engine back to proper clearances and oil pressure for years of reliable service.
What You’re Getting
- Precision-manufactured bearings machined to .010″ oversize specifications for proper clearance
- High-quality materials that handle the loads and heat cycles farm engines put out
- Complete set for a full main bearing replacement—no hunting for individual bearings
- Direct replacement for worn factory bearings when the crankshaft has been turned .010″ undersize
Built for Real Farm Work
This bearing kit fits International Harvester 100 series, 200 series, Super A-1 series, Super AV-1 series, and Super C series tractors. These are the utility and row-crop tractors that built America’s farms, handling everything from loader work to field cultivation. Whether you’re running a Farmall or IH utility tractor, this kit restores your engine to factory specifications.
Made to Last
TISCO builds these bearings to handle the punishment that farm engines dish out. The materials resist oil breakdown and temperature extremes that can destroy cheaper bearings. These .010″ bearings work with matching .010″ rod bearings to give you a complete bottom-end rebuild that’ll keep running season after season.
Installation Notes
This kit is for engines where the crankshaft journals have been turned .010″ undersize by a machine shop. Make sure your crank work is done properly and that bearing clearances are checked with plastigauge before final assembly. While you’re this deep in the engine, it’s a good time to replace your rod bearings and check the oil pump.
