Description
When you’re hearing that telltale knock from deep in your Oliver’s engine or the oil pressure’s not what it used to be, it’s time to give that old workhorse the rebuild it deserves. This main bearing kit contains everything you need to restore proper crankshaft support and get your engine running smooth and quiet again. There’s no sense in doing half the job when you’ve got the oil pan off anyway.
What You’re Getting
- Complete set of standard-size main bearings engineered for Oliver tractor engines
- Precision-manufactured bearing shells that meet or exceed original specifications
- Quality TISCO construction built to handle the heavy-duty cycles of farm work
- Direct replacement bearings that fit right in place without machining or modifications
Built for Real Farm Work
Oliver tractors were built to work hard, and this bearing kit matches that same commitment to durability. Whether you’re restoring a classic Oliver for show work or rebuilding the engine in your daily-use tractor, these bearings provide the foundation your crankshaft needs to handle years of field work, loader duty, and everything else you throw at it.
Made to Last
Engine bearings take tremendous loads and heat cycles, especially in older tractors that see steady use. These bearings are manufactured with proper materials and heat treatment to handle the demanding conditions inside your Oliver’s engine block. They’re designed to maintain proper oil clearances and protect your freshly rebuilt crankshaft.
Installation Notes
Main bearing replacement is part of a complete engine rebuild – not a job you tackle with the engine still in the tractor. Make sure your crankshaft journals are within specification and properly polished before installing new bearings. Check bearing clearances with Plastigauge and follow proper torque specs for the main caps. It’s also the perfect time to replace your rod bearings, seals, and gaskets while everything’s apart.
