Description
When you’re turning tight corners with a loader full of grain or trying to line up perfectly with a bale in the field, heavy steering can turn precision work into a wrestling match. When your power steering starts feeling heavy or you notice fluid dripping from the orbital unit, worn seals are usually the culprit. This complete seal kit rebuilds your Massey Ferguson’s orbital steering unit (part 4655), stopping leaks and restoring the smooth, effortless steering you depend on. This Ognibene orbital unit is the heart of your Fiat’s power steering system, metering hydraulic flow to give you fingertip control when you need it most.

Whether you’re running an 80-90 on hay ground or pushing a 180-90 through heavy soil conditions, precise steering control makes the difference between getting the job done efficiently and fighting the machine all day.
Made to Last
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. This Ognibene unit is built specifically for the demanding hydraulic pressures and constant operation that farm tractors require. The precision-machined valve chambers and quality seals resist the wear that comes from thousands of steering cycles through long work seasons.
Good to Know
After installation, bleed the system thoroughly – air causes jerky steering. Make sure your hydraulic fluid is clean before installing – contaminated fluid will shorten the life of any steering component. Check your hydraulic fluid level and condition first – dirty or low fluid can cause steering problems that look like valve issues. This unit also fits some Zetor models, so it’s a versatile replacement for European tractors of this era.
