Description
When you’re hearing howling from the rear end or noticing gear oil spots under your parked tractor, chances are your differential pinion seal is done for. This seal protects the crown wheel and pinion assembly – the heart of your rear differential that transfers power to the wheels. Once that seal starts leaking, contamination gets in and expensive gear oil gets out, setting you up for a major repair bill if left alone.
What You’re Getting
- High-grade seal that keeps differential oil contained while blocking dirt and moisture
- Precision fit designed specifically for Ford New Holland differential housings
- Heat-resistant materials that handle the temperature swings from field work
- Direct replacement that restores factory sealing without modifications
Built for Real Farm Work
This seal fits a wide range of Ford New Holland tractors from the compact TD series utility tractors up through the powerful TM series row-crop machines. These tractors handle everything from loader work and hay operations to heavy tillage and transport duties. Whether you’re running a TD70 on a livestock operation or a TM190 pulling a big planter, they all depend on proper differential sealing to keep working reliably.
Made to Last
High-quality nitrile rubber construction resists heat, chemicals, and agricultural fluids while maintaining flexibility through temperature extremes. The reinforced design handles the pressure and vibration that comes with heavy implement work, giving you the durability needed for long service life in demanding farm conditions.
Installation Notes
Replacing this seal requires dropping the differential cover and removing the pinion gear – it’s typically a job for someone comfortable with gear work or a qualified shop. Inspect the pinion shaft where the seal rides for scratches and polish out imperfections with fine emery cloth before installing the new seal. Check your differential fluid level and condition while you’re in there, as contaminated oil can shorten seal life.
