When your International Harvester starts knocking or you notice oil pressure dropping, it’s often the main bearings telling you they’ve had enough. These bearings take all the punishment from the crankshaft, and when they wear out, you’re looking at serious engine damage if you keep running. This .010 inch oversize main bearing kit is what you need when your crankshaft journals have been machined .010 undersized to clean up the wear.
What You’re Getting
- Precision-manufactured bearings sized .010 oversize to match your machined crankshaft
- Complete set includes all main bearings needed for your engine rebuild
- Quality construction that handles the heavy loads and heat cycles of farm work
- Direct replacement during engine overhaul or rebuild projects
Built for Real Farm Work
This kit works with a range of International Harvester tractors that have had their crankshafts machined for rebuild. Whether you’re overhauling the engine in your utility tractor or rebuilding a work horse that’s been pulling implements for decades, these bearings restore the tight clearances your engine needs for proper oil pressure and smooth operation.
Made to Last
Engine bearings don’t get second chances – they either do their job or your engine pays the price. These bearings are manufactured to handle the constant rotation, heavy loads, and temperature swings that come with agricultural use. The precise tolerances ensure proper oil film thickness and long service life.
Good to Know
Installing main bearings requires the crankshaft to be removed and the engine block prepared properly. Make sure your machine shop has turned the crankshaft journals .010 undersized before ordering these oversize bearings. Check bearing clearances with Plastigauge during assembly – proper clearance is critical for oil pressure and bearing life. This is typically part of a complete engine rebuild, so consider what other components need attention while you’re in there.
