Description

Nothing’s worse than walking out to your tractor and seeing a puddle of gear oil under the front axle. When you spot oil on your front wheels or drops on the shop floor, that failed half shaft seal isn’t just messy—it’s letting expensive gear oil leak out while dirt and water work their way in. This replacement seal stops the leak and keeps your front axle components properly protected.

What You’re Getting

Precision 30x44x14mm dimensions that match your factory seal exactly
AG66 type specification designed specifically for your MF 4200/4300 axle
Quality rubber compound that resists hot gear oil while staying flexible in cold weather
Steel reinforcement that prevents distortion under pressure and maintains proper fit
Direct replacement that installs just like the original seal

Built for Real Farm Work

Your Massey Ferguson 4200 and 4300 series tractors put their front axles through plenty—whether you’re working muddy fields with a loader, pulling equipment through dusty conditions, or traveling wet roads between jobs. These seals need to contain gear oil while keeping contaminants out, protecting those expensive differential gears and bearings that keep your 4WD system working reliably.

Made to Last

This seal features precision-molded lips that maintain proper contact with your half shaft throughout its rotation. The 14mm width provides plenty of sealing surface for reliable performance, while the steel reinforcement keeps everything properly positioned even under the pressure spikes common in front axle systems. The AG66 specification ensures it’s built for your specific axle design.

Installation Notes

Clean the seal bore thoroughly and check your half shaft surface for wear or scoring before installing. Use a proper seal driver to install evenly—cocking it during installation will cause immediate failure. Pre-lubricate the seal lips with gear oil and replace both sides for best results. If you keep having leaks after replacing seals, check those bearings—excessive shaft movement from worn bearings will destroy even new seals.
