The Case 850K Series 2 skid steer is a robust machine used in a variety of construction, agricultural, and landscaping applications. Known for its strength and maneuverability, the 850K Series 2 is typically reliable. However, like any piece of heavy machinery, it can occasionally encounter mechanical issues. One of the more troubling issues that some operators have faced is the lack of steering functionality. This problem can bring work to a halt and pose safety concerns if not addressed promptly. This article explores the potential causes of steering failures in the Case 850K Series 2 and provides solutions for troubleshooting and fixing the issue.
Understanding the Steering System in the Case 850K Series 2
The steering system in the Case 850K Series 2 is a crucial component for maneuvering the machine. It uses a hydrostatic steering mechanism, which relies on hydraulic pressure to control the movement of the wheels. The hydraulic steering system ensures smooth turns and precise control, making the skid steer highly maneuverable, even in tight spaces.
When the steering fails to respond in the Case 850K Series 2, it can be due to several underlying issues. These issues could be mechanical, electrical, or hydraulic in nature. Understanding the potential causes will help pinpoint the problem more efficiently.
To diagnose and fix the no steering issue on the Case 850K Series 2, follow this step-by-step troubleshooting guide:
A construction company operating a Case 850K Series 2 skid steer found that the steering had completely failed during a major earthmoving project. The operator reported that the machine would not respond to steering inputs, making it impossible to maneuver the skid steer.
Upon inspection, the maintenance team discovered that the hydraulic fluid level was low, likely due to a small leak in the system. They refilled the fluid, but the issue persisted. Further investigation revealed that the hydraulic pump was worn, causing a drop in pressure. After replacing the pump and flushing the hydraulic system, the steering function was restored to full capacity.
This case highlights the importance of regular hydraulic system maintenance, including monitoring fluid levels and checking for leaks. Additionally, it demonstrates the complexity of modern skid steer systems, which can be affected by a range of issues, from fluid problems to pump failure.

It uses a hydrostatic steering mechanism, which relies on hydraulic pressure to control the movement of the wheels. The hydraulic steering system ensures smooth turns and precise control, making the skid steer highly maneuverable, even in tight spaces.
- Hydrostatic Steering: This system uses hydraulic fluid to transmit pressure to the steering cylinders, which then turn the wheels. When functioning properly, the steering is smooth and responsive, allowing for tight turns and excellent control on uneven terrain.
- Components Involved:
- Steering Cylinder: This component is responsible for physically turning the wheels when hydraulic pressure is applied.
- Hydraulic Pump: The hydraulic pump generates the pressure needed for the steering system to operate.
- Control Valve: This valve directs the hydraulic fluid to the appropriate steering cylinders, depending on the direction the operator wants to turn.
