Description
When you’re wrestling with a loose or missing power steering ram nut, you know it right away. The steering starts feeling sloppy, the ram moves around where it shouldn’t, or worse—hydraulic fluid starts leaking from the connection points. This small but critical fastener keeps your power steering cylinder securely mounted so you can maintain that smooth, effortless steering control your tractor’s supposed to have.
What You’re Getting
- Precision-threaded nut designed specifically for Fiat power steering rams
- Heavy-duty steel construction that handles hydraulic pressures and vibration
- Exact-fit replacement that secures your steering cylinder properly
- Corrosion-resistant finish that stands up to hydraulic fluid and weather
Built for Real Farm Work
This nut fits the power steering systems on Fiat 90 Series tractors (55-90 through 180-90) and Winner Series models (F100-F140). These are solid, dependable machines used for everything from cultivation and hay work to loader operations around the farmyard. When you’re making tight turns with a loaded bucket or navigating between buildings, proper power steering operation isn’t just about comfort—it’s about safety and getting work done efficiently.
Made to Last
Farm equipment takes a beating, and even small fasteners like this need to hold up under constant pressure and vibration. This nut is built with high-strength steel that won’t stretch or strip under the hydraulic pressures your steering system generates. The threads are precision-cut for a secure fit that won’t back off during operation.
Installation Notes
This is a straightforward replacement—just make sure to torque it to specification once installed. Before removing the old nut, depressurize your hydraulic system and have some rags ready for cleanup. If the old nut was really loose, inspect the ram mounting point for wear before installing the new one.
