Description

When your 4WD tractor starts making grinding noises from the front axle or you’re losing power to the front wheels, it’s usually a sign that differential bearings have had enough. Your 4WD tractor earns its keep when conditions get tough and this bearing is critical for transferring power from your transmission to the front axle. This replacement bearing restores smooth operation and gets your tractor back to pulling evenly through mud, snow, or steep terrain.

What You’re Getting

Precise 65mm inner diameter, 100mm outer diameter, and 23mm width for exact OEM fit
Modern bearing technology with improved sealing to outlast original equipment
Precision machining ensures proper shaft support throughout its service life
Direct replacement—no modifications needed for installation

Built for Real Farm Work

This bearing fits an impressive range of workhorse tractors including Massey Ferguson 200, 300, 3000, 3600, 4200, 4300, 6100, 6200, and 8200 series models, plus Fiat 66, 76, 86, 90, 93, and 94 series tractors. Whether you’re running a MF 3690 with a front loader, pulling heavy tillage equipment with a 6190, or working steep ground with any of these reliable machines, this bearing handles the constant stress of 4WD operation.

Made to Last

Differential bearings take tremendous loads, especially in 4WD applications where they’re constantly supporting rotating weight while handling torque transmission. This replacement uses quality steel construction and proper heat treatment to stand up to the punishment of agricultural work. The bearing maintains its dimensional stability through temperature changes and contamination that would destroy lesser quality parts.

Installation Notes

Replacing differential bearings requires removing the front axle assembly, so it’s a job for someone comfortable with major tractor work. Clean all old grease and debris from the housing before installation, and pack the new bearing with quality differential grease. Check the differential housing for wear or damage while you’ve got everything apart—it’s also a good time to inspect seals and replace if needed.
