What You’re Getting

  • Complete orbital steering unit seal kit with all necessary O-rings and seals

  • Quality materials designed for millions of steering cycles
  • Saves significant money over buying a replacement orbital unit

Built for Real Farm Work

Your Massey Ferguson’s orbital steering unit is the heart of the power steering system, metering hydraulic flow for effortless control. Located between your steering wheel and hydraulic system, it takes constant use and pressure cycles. Whether you’re plowing tight headlands, maneuvering around buildings with a loader, or making precision passes for planting, smooth power steering makes the difference between comfortable work and a back-breaking day.

Made to Last

Each seal is manufactured from materials that resist hydraulic fluid breakdown while maintaining flexibility through constant pressure cycles. The kit includes every seal needed for complete rebuilding, ensuring all wear points are addressed. These aren’t generic seals—they’re specifically designed for orbital unit service and maintain proper sealing under the demanding conditions of farm work.

Installation Notes

Rebuilding an orbital unit requires cleanliness and patience but saves significant money over replacement. Mark the unit’s position relative to steering linkage for proper timing during reinstallation. Clean all parts thoroughly and inspect the valve spool and sleeve—any scoring causes continued leaking. Install new seals carefully using proper tools, lubricate with clean hydraulic fluid, and pay attention to seal orientation as many are directional. After installation, bleed the system thoroughly since air causes jerky steering.
