When you hear that telltale knocking from deep in your engine or feel excessive vibration while idling, worn main bearings are often the culprit. This .020″ undersized main bearing kit is designed to restore proper crankshaft support and get your International Harvester tractor back to running smooth and strong. These bearings provide the precision fit needed when your crankshaft journals have been machined .020″ undersized during an engine rebuild.
What You’re Getting
- Complete set of main bearings machined to .020″ undersize specification for proper crankshaft clearance
- TISCO quality construction that meets or exceeds original equipment durability standards
- Precision-manufactured bearing shells that handle the loads and stresses of farm work
- Direct replacement for original International Harvester main bearing sets during engine overhaul
Built for Real Farm Work
This kit fits International Harvester 100 series, 200 series, Super A-1 series (prior to S/N 310300), Super AV-1 series (prior to S/N 310300), and Super C series tractors. Whether you’re running a utility model for daily chores or a row-crop machine for field operations, these bearings restore the smooth crankshaft rotation that keeps your engine running efficiently under load.
Made to Last
Farm engines take a real beating from constant operation under heavy loads, temperature swings, and exposure to dirt and contaminants. These replacement bearings use quality materials and precision manufacturing to deliver the same reliable performance as original equipment, ensuring your rebuilt engine will provide years of dependable service.
Good to Know
These .020″ undersized bearings are specifically for crankshafts that have been machined undersize during rebuilding. Always verify your crankshaft measurements before ordering, and check that your connecting rod bearings match if you’re doing a complete rebuild. Proper torque specifications and assembly procedures are critical for bearing longevity.
