Description

When you’re hooking up implements or adjusting your three-point hitch and notice hydraulic fluid leaking around where the top arm enters the rockshaft housing, that’s this seal calling for replacement. A worn top arm seal doesn’t just make a mess—it lets expensive hydraulic fluid drain away while allowing dirt and moisture to contaminate your hydraulic system. This seal keeps things sealed up tight so your three-point hitch lifts properly when you need it to.

What You’re Getting

Precise fit that seals the top arm shaft where it enters the housing
Quality rubber construction that handles hydraulic pressure and temperature swings
Durable design that stands up to the constant movement of three-point operation
Direct replacement—no modifications needed, just remove the old and install the new

Built for Real Farm Work

This seal fits a wide range of Ford New Holland tractors from utility models up through row-crop machines. Whether you’re running a compact tractor with a box blade, a mid-size machine pulling a disc, or a larger tractor handling heavy implements, your three-point hitch gets plenty of use raising and lowering equipment all season long.

Made to Last

Farm hydraulics work hard, and this seal is built to keep up. The rubber compound stays flexible in cold weather and won’t break down from hot hydraulic fluid or exposure to farm chemicals. It’s designed to handle the constant cycling that comes with regular implement use.

Good to Know

Installation usually requires removing the top arm, so it’s a good time to check the arm bushings and pins while you’re at it. Clean the shaft and housing thoroughly before installing the new seal—any dirt or scratches can cause the new seal to leak. A light coating of hydraulic fluid on the seal lip helps it slide into place without damage.
