Orbital Steering Unit for Massey Ferguson & Case Tractors

Description

When your tractor starts feeling like you’re wrestling a bull every time you turn the wheel, that’s your orbital steering unit telling you it’s time for a replacement. Heavy steering, especially at low RPM, fluid leaks below the steering column, or intermittent steering that works sometimes but not others – these symptoms make precision work frustrating and loader operation downright dangerous. This 100cc orbital steering unit restores the smooth, predictable control you need to safely operate your MF or Case tractor.

What You’re Getting

• 100cc displacement (OS specification) provides appropriate steering response for your tractor size
• 3/4″ JIC hydraulic connections for secure, leak-free installation
• WITHOUT relief valve configuration for specific system requirements
• Direct replacement for multiple MF and Case models – no modifications needed
• Precision-manufactured internals that handle constant use and pressure cycles

Built for Real Farm Work

This unit fits a wide range of workhorses from compact Case C50s perfect for specialty crops to powerful 995XLs handling heavy tillage. Whether your MF 300 navigates orchard rows or your Case 885 operates a loader all day, your orbital steering unit is the heart of the power steering system, located between your steering wheel and hydraulic system, taking constant use and pressure cycles. From 50 to 100+ horsepower machines, they all depend on reliable steering control for safe operation.

Made to Last

This orbital unit is built to handle the demanding conditions of farm work. The valve spool and sleeve must be perfectly smooth for leak-free operation, and this replacement provides the precision engineering needed for years of dependable service. The 100cc displacement delivers strong assist even with heavy implements or when working in difficult conditions.

Good to Know

This is the WITHOUT relief valve version – make sure that matches your system before ordering. Note the 3/4″ JIC fitting requirement too. This unit specifically fits units marked 4655, common across many Massey Ferguson models. Installation requires absolute cleanliness since contamination destroys these precision components. After installation, bleed the system thoroughly – air causes jerky steering. Prime the unit before mounting to prevent dry startup, and test operation at various speeds to ensure smooth response throughout the range.
