Description
If you’ve got oil streaks running down your rear wheels, you know it’s more than just a messy problem—every drop on the ground is one less drop protecting your expensive axle bearings and brakes. This precision axle hub seal stops leaks at the source, keeping gear oil where it belongs while preventing dirt and moisture from destroying your hub components. When you’re dealing with tractors that put in long days, a failed seal can turn into bearing replacement or worse.
What You’re Getting
- Precision dimensions (12.89 x 135.51 x 165.50mm) for ZF APL345/350 axles ensure a perfect fit without guesswork
- Heavy-duty construction handles high-pressure gear oil without leaking even under demanding conditions
- Double-lip design keeps oil in and contamination out for reliable protection
- Heat-resistant materials maintain seal integrity in demanding conditions through temperature extremes
- Direct replacement that restores your original sealing performance
Built for Real Farm Work
Whether you’re running a Ford TW series handling heavy tillage, a John Deere 3640 on hay duty, or a Case IH 956 working livestock, they all share similar ZF axle designs that need proper sealing. These tractors ranging from 75-150 HP are the workhorses on many farms, and a leaking hub seal doesn’t just waste expensive gear oil – it can contaminate brake linings, destroy wheel bearings, and leave you stranded when components run dry.
Made to Last
This isn’t just any rubber ring – it’s a precisely engineered seal designed for the specific challenges of agricultural axles. The 165.50mm outer diameter fits perfectly in your hub housing, while the 135.51mm inner diameter grips the axle shaft with just the right pressure. That 12.89mm width provides the sealing surface needed to handle gear oil pressure without distortion. The materials are formulated to handle the constant flexing and heat cycles that eventually destroy lesser seals.
Installation Notes
Installation requires removing the wheel and hub – budget 2-3 hours per side. The key is cleanliness; any dirt during installation causes immediate seal failure. Use a proper seal driver to install evenly without damaging the seal lips. Inspect the axle shaft where the seal rides – even minor scratches create leak paths. Polish out imperfections with fine emery cloth. If one seal has failed, the opposite side probably needs attention too.
