Description
When your steering starts getting heavy or develops those nerve-wracking dead spots, you know something’s wrong with that orbital unit. Your Massey Ferguson’s orbital steering unit is the heart of the power steering system, metering hydraulic flow for effortless control, and when it starts wearing out, every turn becomes a wrestling match. This 125 OSP orbital steering unit with M18 thread connections gets you back to the smooth, predictable steering these workhorses were built for.
What You’re Getting
- 125cc displacement that gives you the right steering ratio for your tractor’s size
- OSP (Open Center Priority) valve design that prioritizes steering flow when you need it most
- M18 thread hydraulic connections that match factory specifications exactly
- Direct bolt-in replacement – no modifications needed
- Precision internal components that restore original steering feel
Built for Real Farm Work
This orbital unit fits Massey Ferguson 300 and 3000 series tractors that have been the backbone of countless farms for decades. Whether you’re running a loader, working tight spaces around buildings, or pulling implements that require precise control, these mid-range tractors need reliable steering to stay productive and safe. When the orbital unit wears internally, you’ll deal with everything from excessive play to complete loss of power assist.
Made to Last
Located between your steering wheel and hydraulic system, it takes constant use and pressure cycles, so this unit is built to handle the punishment. Quality internal components and precision machining ensure it’ll give you years of reliable service, just like the original.
Installation Notes
The M18 thread specification is critical – make sure your tractor uses this size before ordering. Mark the unit’s position relative to steering linkage for proper timing during reinstallation and bleed the system thoroughly – air causes jerky steering. Keep everything spotlessly clean during installation, as contamination destroys these precision components fast.
