Description
When your 4WD isn’t pulling like it should, or you’re hearing clunking noises from the front axle during turns, chances are your drive shaft is calling it quits. This vital connection transfers power from your transmission to the front wheels, and when it fails, you lose that extra traction you need for tough field conditions. Your 4WD tractor earns its keep when conditions get tough – pulling through muddy fields, climbing steep slopes with a loaded spreader, or pushing snow in winter. This bearing and carrier assembly is critical for transferring power from your transmission to the front axle.
What You’re Getting
- Precision-manufactured 1120mm length shaft built to exact specifications
- Heavy-duty construction designed to handle the torque loads of agricultural work
- Direct replacement for your worn or damaged original shaft
- Quality materials that resist wear from constant rotation and stress
Built for Real Farm Work
This kit fits Massey Ferguson 300 series (365, 375, 390, 398, 399) 4WD tractors that see demanding duty in all kinds of conditions. Whether you’re pulling through heavy soil in spring, handling loader work around the barn, or tackling tough terrain where you need maximum traction, this shaft keeps power flowing to your front wheels when you need it most.
Made to Last
Driveshaft bearings take tremendous loads, especially in 4WD applications where they’re constantly supporting rotating weight while handling torque transmission. This replacement assembly uses modern bearing technology with improved sealing to outlast original equipment. The robust carrier housing resists the flexing and stress that cause premature bearing failure, while precision machining ensures proper shaft support throughout its service life.
Installation Notes
This is a major repair that typically requires splitting the tractor and specialized tools for proper installation. If you’re tackling this yourself, make sure to inspect related driveline components while you’ve got everything apart – worn universal joints or bearings can quickly destroy a new shaft. Always follow proper torque specifications during reassembly to prevent premature failure.
