Description
When your steering starts feeling heavy during loader work or you’re wrestling the wheel while turning around at the end of the field, your orbital steering unit is likely wearing out. This orbital unit is the heart of your power steering system, metering hydraulic flow for effortless control as it sits between your steering wheel and hydraulic system. This replacement gets you back to fingertip steering so you can focus on the work instead of fighting your tractor.
What You’re Getting
- Complete orbital steering unit with integrated relief valve for proper system pressure control
- Factory-spec unit designed specifically for tractors with the 4655 part reference
- 3/4 JIC hydraulic fittings for secure, leak-free connections to your hydraulic lines
- Built-in pressure relief protects your steering system from damage during high-pressure situations
- Direct replacement that installs with your existing mounting hardware and hydraulic connections
Built for Real Farm Work
This orbital unit handles the daily demands of both Massey Ferguson and Case IHC utility tractors. From compact models perfect for livestock operations to mid-range workhorses used for row crops and hay production, these tractors see everything from gentle pasture mowing to heavy tillage work. The integrated relief valve ensures your steering system stays protected even when you’re muscling through tough conditions with a loaded loader or pulling heavy implements.
Made to Last
Farm tractors put steering systems through constant pressure cycles and temperature changes. This orbital unit is built with precision-machined components and quality seals that handle the hydraulic pressures and vibration that come with serious farm work. The integrated relief valve provides an extra layer of protection, preventing pressure spikes from damaging internal components when you hit obstacles or make sharp turns under load.
Installation Notes
Mark your old unit’s position relative to the steering linkage before removal – proper timing during reinstallation keeps your steering geometry correct. The 3/4 JIC fittings connect directly to your existing hydraulic lines without adapters. After installation, bleed the system thoroughly since air causes jerky steering. Test the steering at various RPMs and loads to ensure smooth operation.
