Hydraulic Pump Shaft Oil Seal for Ford NAA, 600-900 and 2000-4000 Series Tractors (1953-1964)

Description

Nothing ruins a good day of farming like hydraulic fluid puddled under your tractor and a three-point hitch that won’t lift properly. When you notice that telltale red puddle or feel the hitch drifting down while you’re trying to work, there’s a good chance this little but mighty oil seal has given up the ghost. This shaft seal keeps your hydraulic pump fluid where it belongs and prevents dirt from getting into places that’ll cost you serious money.

What You’re Getting

• Precise dimensions (0.9350″ inner diameter, 2.004″ outer diameter, 0.5315″ width) for a perfect seal
• Quality materials that handle the constant rotation and pressure of hydraulic pump operation
• Direct replacement that fits like the original – no modifications needed
• Proven design that’s been keeping these classic Fords running for decades

Built for Real Farm Work

This seal fits the hydraulic systems on Ford’s workhorse tractors from the NAA (Golden Jubilee) through the early 4000 series models built from 1953 to 1964. These are the tractors that built American agriculture – from the compact NAA perfect for smaller farms to the robust 4000 series handling serious fieldwork. Whether you’re running a three-point mounted cultivator, operating a loader, or powering hydraulic cylinders on attachments, this seal keeps everything working smoothly.

Made to Last

Farm equipment seals take a beating from heat, pressure, and the constant flexing that comes with pump operation. This seal is built with materials designed to handle the specific demands of hydraulic systems – resisting the breakdown that cheaper seals experience from exposure to hydraulic fluid and temperature swings.

Good to Know

When replacing this seal, it’s smart to inspect the pump shaft for wear or scoring that could cause premature seal failure. Clean everything thoroughly before installation – any dirt or debris will damage the new seal quickly. A thin coat of clean hydraulic fluid on the seal lip during installation helps it seat properly and prevents dry-start damage.
