Description
When your IH tractor starts knocking or you’re doing an engine rebuild, the main bearings are at the heart of the job. These are the bearings that support your crankshaft, and when they’re worn out, you’ll know it—whether it’s through that telltale knock under load or metal shavings in your oil. This standard-size main bearing kit gives you everything you need to get your engine back to running smooth and quiet.
What You’re Getting
- Complete set of main bearings engineered to OEM specifications for proper fit and clearances
- Standard size bearings that work with an unground crankshaft that’s still within spec
- Quality construction from TISCO that’s built to handle the demands of agricultural work
- All the bearings you need in one kit—no guessing which ones to order
Built for Real Farm Work
This bearing kit is designed for International Harvester tractor engines that have seen their share of long days but still have good crankshafts. Whether you’re running a utility tractor for chores around the farm or a larger row-crop machine for serious fieldwork, proper main bearings are what keep your crankshaft centered and your engine running right. These bearings handle the heavy loads and constant vibration that come with farm use.
Made to Last
Engine bearings take more punishment than just about any other part in your tractor. They deal with thousands of combustion cycles, temperature swings, and the occasional dust that gets past your air filter. These bearings are manufactured to handle those conditions with the right materials and tolerances to give you reliable service for years to come.
Good to Know
Installing main bearings means dropping the oil pan and probably pulling the engine, so it’s a good time to check your rod bearings, oil pump, and other wear items while you’re in there. Make sure your crankshaft journals are still standard size and not scored—if they need machining, you’ll want undersize bearings instead. A good machine shop can measure everything and confirm you’ve got the right parts before you start assembly.
