Description

When you notice knocking sounds from your engine or see oil pressure dropping during long work days, worn main bearings are usually the culprit. These critical components keep your crankshaft properly positioned and lubricated, preventing catastrophic engine damage that can sideline your tractor for weeks. This main end bearing set gives you the foundation for a reliable engine rebuild that’ll keep you working when the crops need attention.

What You’re Getting

Complete bearing set engineered specifically for the 1104C Perkins engine’s operating demands
Precision-manufactured surfaces that maintain proper oil film thickness under varying loads
Heat-treated steel construction designed to handle the stresses of agricultural work
Direct replacement bearings that restore original factory clearances and performance
Quality materials that resist wear from contaminated oil and high operating temperatures

Built for Real Farm Work

These bearings power through your toughest jobs in Massey Ferguson tractors equipped with the reliable 1104C Perkins engine. Whether you’re running a loader through rocky soil, pulling heavy implements during planting season, or powering PTO equipment for long hours, proper main bearing support keeps your engine running smoothly under load.

Made to Last

Engine bearings take tremendous loads, especially in agricultural applications where engines run for hours at varying RPMs, and these bearings are manufactured to handle the stresses of farm work while providing the proper oil film thickness for reliable lubrication and heat dissipation. The materials resist the thermal cycling that comes with stop-and-go field work and maintain their structural integrity through seasons of demanding use.

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, and consider replacing the connecting rod bearings at the same time if you’re doing a complete bottom-end rebuild. Keep everything spotlessly clean during assembly and use the proper torque sequence specified in your service manual.
