Description
When your disc harrow starts leaving oil spots in the field or you can see grease working its way past the hub seals, it’s time to swap out those worn seals before dirt gets in and damages your bearings. This Timken oil and grease seal fits the hub on your John Deere 630 disc harrow, keeping lubrication where it belongs and contaminants where they don’t.
What You’re Getting
- Genuine Timken quality construction that matches OEM specifications
- Double-lip design that seals tight against oil and grease leakage
- Durable materials that handle the heat and pressure of field operations
- Precise 0.3 inch width dimension for proper fit and function
Built for Real Farm Work
This seal is designed specifically for the 6-bolt hub used on John Deere 630 disc harrows, along with other JD disc and cultivator models. Whether you’re working heavy clay ground in the spring or doing light discing after harvest, your disc harrow takes a beating bouncing over rocks and through tough soil conditions.
Made to Last
Timken seals are built to handle the constant flexing and pressure changes that come with disc harrow operation. The quality rubber compound stays flexible through temperature swings while the metal case provides structural strength that won’t distort under load.
Installation Notes
This is a direct replacement seal that installs just like the original. Clean the hub bore thoroughly and check for any nicks or scratches that could cause the new seal to leak. A thin coat of grease on the seal lip helps it seat properly and extends service life.
