Description

When your tractor engine starts knocking or showing signs of bearing wear, you don’t want to be sidelined during planting or harvest season. A failing main bearing causes engine noise and can quickly lead to catastrophic engine damage if left unchecked. This replacement main bearing restores proper crankshaft support and keeps your engine running smooth and reliable when there’s work to be done.

What You’re Getting

Quality construction that’s properly heat-treated and manufactured to handle the demanding conditions of agricultural use
Precision manufacturing with proper clearances for smooth operation and materials that stand up to the punishment
Direct replacement design that fits like the original factory bearing
Engineered for long service life in agricultural diesel engines

Built for Real Farm Work

This main bearing is designed for tractor diesel engines that handle everything from daily chores to heavy field work. Engine bearings take tremendous loads, especially in agricultural applications where engines run for hours at varying RPMs. Whether you’re running a utility tractor for loader work or operating a high-horsepower machine through tough soil conditions, proper main bearing support is critical for engine longevity.

Made to Last

Farm work means dealing with dust, moisture, and heavy loads that can quickly destroy inferior bearings. This replacement bearing uses materials and construction methods designed to withstand the constant vibration, temperature swings, and demanding operating conditions that come with agricultural equipment. It’s built to keep your engine running season after season.

Installation Notes

Installing main bearings requires having your crankshaft machined by a qualified machine shop to the proper dimensions. Always check crankshaft journal diameter with a micrometer before ordering. This is typically part of a complete engine rebuild, so consider inspecting all bearings and engine components while you’re in there. Professional installation is strongly recommended for this critical engine component.
