Description
If you’ve noticed oil weeping from the steering box or felt sloppy steering that’s getting worse, this inner steering rocker shaft seal is likely what you need. When this small but critical seal fails, it lets gear oil leak out while allowing dirt and moisture in—a recipe for expensive steering box damage. This quality replacement seal keeps your Ford’s steering system properly lubricated and protected.
What You’re Getting
- Precise fit that stops oil leaks without affecting steering feel
- Durable rubber construction that handles temperature swings and gear oil
- Metal case provides proper retention and prevents seal migration
- TISCO quality that meets or exceeds original Ford specifications
- Direct replacement for worn original seals—no modifications needed
Built for Real Farm Work
This seal fits a wide range of Ford tractors from the classic Major and Super Major models through the popular 4000 series utility tractors. Whether you’re running a 1950s Major for hay work, a 4000 for general farming, or a 4600 with a loader, these tractors see hard use where reliable steering is essential for safe operation and precise implement control.
Made to Last
The steering box takes constant abuse from road vibration, loader work, and turning against implement resistance. This seal uses quality rubber compounds that resist hardening from heat cycles and won’t swell from contact with gear oil. The metal case ensures the seal stays put even under the pressure changes that occur during steering operation.
Installation Notes
While you can replace this seal without major disassembly, it’s smart to check the rocker shaft for wear grooves while you’re in there. Clean the seal bore thoroughly and apply a thin coat of gear oil to the seal lip before installation. If the steering has been sloppy for a while, consider checking the sector gear and other steering box components at the same time.
