Orbital Steering Unit for Fiat 90 Series & Zetor 2-Ram Axle Tractors

Description

When your Fiat or Zetor starts wandering down the field or you’re fighting the wheel just to keep straight, a worn orbital steering unit isn’t just annoying—it’s dangerous. These bigger tractors with dual steering cylinders need precise hydraulic control to handle their size and weight safely. This Ognibene 160 OSP orbital unit restores the smooth, predictable steering response you need for everything from loader work to field operations.

What You’re Getting

• 160cc displacement specifically sized for 2-ram steering systems
• OSP (Open Center Priority) design keeps steering responsive at all engine speeds
• 1/2 inch BSP thread connections that match your tractor’s hydraulic fittings
• Ognibene quality engineering that meets or exceeds OEM specifications
• Precision metering that gives both steering cylinders equal response

Built for Heavy-Duty Work

This orbital unit serves the powerful Fiat 90 series tractors and compatible Zetor models equipped with 2-ram steering axles. Whether you’re pulling heavy tillage equipment, operating with a loaded front-end loader, or maneuvering around buildings and livestock, these tractors demand steering systems that can handle the job. The dual cylinder setup provides the muscle needed to turn large tires under load, but only when the orbital unit meters hydraulic flow properly.

Made to Last

The 160cc displacement and robust internal components handle the high pressures and constant cycling that comes with farm work. Ognibene’s reputation in hydraulic steering means this unit is built to withstand temperature swings, contamination, and the daily punishment of agricultural operations. Quality internal seals and precision machining ensure years of reliable service.

Installation Notes

This is a direct replacement for tractors with 2-ram axle configurations and 1/2 inch BSP fittings. Keep everything spotless during installation—dirt kills steering components fast. Flush your entire steering system with clean fluid before installing the new unit, and bleed both cylinders thoroughly to ensure even response. If one cylinder still acts sluggish after installation, check your cylinder seals and mechanical linkages too.
