Description
When you’re deep into a major engine rebuild, there’s no room for compromise on the parts that matter most. Your crankshaft depends on quality main bearings to keep spinning smoothly through thousands of hours of hard work, and worn bearings mean metal-on-metal contact that’ll destroy your crank faster than you can say “seized engine.” This standard-size main bearing set from TISCO gives you the precision fit and durability your International Harvester engine needs to run like new again.
What You’re Getting
- Complete main bearing set in standard dimensions – no machine shop work needed if your crank journals are still in spec
- Precision-manufactured bearings that meet or exceed original equipment tolerances
- Quality materials designed to handle the high loads and temperature cycles of farm tractor engines
- Direct replacement for your International Harvester – same specifications as what came from the factory
- TISCO quality construction that mechanics trust for reliable engine rebuilds
Built for Real Farm Work
International Harvester tractors have powered American farms for generations, from the smaller utility models perfect for hay operations to the big row-crop machines that handle corn and soybean production. Whether you’re rebuilding the engine in your vintage Farmall or getting a workhorse back into service, these bearings are engineered to handle the demands of real farm work – long hours, heavy loads, and everything from cultivating to harvesting.
Made to Last
Engine main bearings take tremendous abuse in farm tractors. They support the full weight of rotating assemblies while dealing with combustion pressures, temperature extremes, and the constant vibration of agricultural work. These TISCO bearings are manufactured with proper clearances and oil groove designs to ensure adequate lubrication reaches all bearing surfaces, preventing the hot spots and scoring that lead to premature failure.
Good to Know
Before installing new main bearings, have your crankshaft journals checked with a micrometer – standard bearings only work if your crank hasn’t been turned undersize. Clean everything thoroughly and use proper torque specifications when reassembling. A good mechanic’s tip: check your oil pump and change the oil filter during the rebuild to make sure those new bearings get clean oil from day one.
