Description

When your tractor starts knocking or showing low oil pressure, worn main bearings are often the culprit. These 30 thousandths oversize main bearings are designed for engines that have been machined to accommodate the larger bearing size during rebuild or overhaul. If you’re rebuilding an engine that’s seen thousands of hours of hard farm work, these oversize bearings help restore proper clearances and get your tractor back to reliable operation.

What You’re Getting

30 thousandths oversize bearings for engines with machined crankshafts
Precise manufacturing ensures proper clearances and oil flow
Quality construction designed to handle the demands of agricultural work
Direct replacement for worn original bearings in rebuilt engines

Built for Real Farm Work

These main bearings fit a wide range of Case IHC tractors from compact utility models to larger row-crop and specialty machines. Whether you’re rebuilding the engine in your loader tractor, hay equipment, or field cultivator, these bearings provide the foundation for reliable engine operation season after season.

Made to Last

Main bearings take tremendous loads and must maintain proper oil clearances under all operating conditions. These bearings are manufactured to strict tolerances using materials that resist wear and maintain their properties through temperature extremes and high-stress operation.

Installation Notes

These are oversize bearings that require a machined crankshaft – they won’t fit standard journals. Always verify your crankshaft has been properly machined to 30 thousandths oversize before installation. Professional engine rebuild with proper torque specifications and clearance checks is recommended for best results.
