Description
If you’ve been chasing hydraulic leaks around your Ford NAA’s lift cover, this O-ring kit is exactly what you need. Those small but critical seals keep your hydraulic system sealed tight where it counts most—the lift cover assembly that houses your three-point hitch hydraulics. When these O-rings start to harden and crack from years of heat and pressure cycles, you’ll notice hydraulic fluid weeping around the cover, and that sluggish lift response tells you it’s time for fresh seals.
What You’re Getting
- Complete set of O-rings designed specifically for NAA lift cover assemblies
- Quality rubber compounds that resist hydraulic fluid and temperature extremes
- Proper seal dimensions to restore factory-tight hydraulic system operation
- All the seals you need for a complete lift cover rebuild in one convenient kit
Built for Real Farm Work
Your Ford NAA might be from the 1950s, but it’s still earning its keep around the farm. These tractors handle everything from cultivation and planting to loader work and general farm maintenance. The three-point hitch system relies on proper hydraulic pressure to lift implements smoothly and hold them in position, whether you’re raising a plow at the end of a row or positioning a bush hog for transport.
Made to Last
These O-rings are manufactured from hydraulic-fluid resistant compounds that handle the constant pressure changes of lift and lower cycles. The rubber stays flexible through temperature swings and resists the breakdown that old-style seals suffer from exposure to modern hydraulic fluids.
Good to Know
This is a perfect winter shop project when you can take your time and do it right. Clean all the O-ring grooves thoroughly with a pick or small screwdriver—old seal fragments left behind cause immediate comeback leaks. Use a dab of clean hydraulic fluid on the new O-rings during installation to prevent damage, and never force them into place.
