The Case 580 CK Extendahoe is one of the most iconic machines in the backhoe loader category. Released in the early 1970s, this model is known for its robust design, versatility, and the unique extendable boom system that gives it extended reach and capabilities compared to other backhoe models. Despite its longevity and performance in various construction and digging tasks, the 580 CK does have its quirks, especially in its hydraulic and steering systems.
In this article, we will focus on one of the common issues experienced by owners of the 1971 Case 580 CK Extendahoe: steering problems. Understanding the root causes and how to address them can significantly improve the longevity and performance of this classic machine.
Steering System Overview
The steering system on the Case 580 CK is a combination of hydraulic power steering and mechanical linkages, making it more responsive and easier to handle than traditional manual steering systems. However, like any hydraulic system, it is prone to certain wear and tear issues, especially in a machine that is over 50 years old.
A key feature of the 580 CK’s steering system is its ability to operate under load, providing enhanced maneuverability even in challenging environments. The hydraulic power steering system relies on a pump, valves, fluid, and hydraulic cylinders to steer the wheels. Problems in any of these components can lead to issues with steering performance.
Common Steering Issues in the Case 580 CK
Here are some of the most common steering issues that owners of the 1971 Case 580 CK Extendahoe may encounter:
1. Low Steering Response or Heavy Steering
One of the most common problems reported is low steering response or unusually heavy steering, which may indicate a hydraulic issue. When the steering becomes difficult or unresponsive, it often points to:
Vibration in the steering wheel while operating the machine is another issue that can arise. This could be caused by:
Leaks are one of the most common and troublesome issues for the hydraulic systems on older equipment like the 580 CK. Common leak sources in the steering system include:
To resolve steering issues on the Case 580 CK, a methodical approach to troubleshooting is necessary. Here’s how to systematically address and resolve the most common steering issues:
1. Check Hydraulic Fluid Levels and Quality
The first step in troubleshooting any hydraulic steering problem is to check the hydraulic fluid levels. Ensure that the fluid is at the proper level according to the service manual specifications.
Visually inspect all the hydraulic hoses and connections leading to and from the steering system. Look for any signs of wear, cracks, or leaks. If any hose is damaged, it should be replaced immediately.
The hydraulic pump is the heart of the steering system. If the steering is heavy or unresponsive, the pump may be failing.
Steering cylinder seals are prone to wear over time, leading to fluid leakage and poor steering performance.
If the hydraulic fluid is contaminated or dirty, cleaning and flushing the system is essential. This process involves removing the old fluid, cleaning the hydraulic components, and refilling the system with fresh fluid.
If vibration persists despite fixing leaks or replacing fluid, you may need to check the alignment of the steering components, such as the tie rods or the steering gear mechanism.
The 1971 Case 580 CK Extendahoe is a durable and reliable machine, but like any older piece of equipment, it may encounter issues over time. Steering problems, particularly related to the hydraulic system, are among the most common complaints from owners of the 580 CK. By following the troubleshooting steps outlined above and addressing potential causes such as hydraulic fluid issues, pump failures, or leaks, you can restore the machine’s steering performance and extend its useful life. Regular maintenance, including fluid checks and system inspections, will help ensure that your Case 580 CK continues to perform reliably for years to come.
The Case 580 CK remains an excellent choice for a variety of construction and agricultural tasks, offering both power and versatility in a compact package. With proper maintenance, this classic backhoe loader can continue to serve as a workhorse on any job site.

Common Steering Issues in the Case 580 CK
Here are some of the most common steering issues that owners of the 1971 Case 580 CK Extendahoe may encounter:
1. Low Steering Response or Heavy Steering
One of the most common problems reported is low steering response or unusually heavy steering, which may indicate a hydraulic issue. When the steering becomes difficult or unresponsive, it often points to:
- Low Hydraulic Fluid Levels: Insufficient hydraulic fluid can cause a lack of pressure in the system, making the steering feel stiff or heavy.
- Hydraulic Pump Failure: The steering pump may be worn out or damaged, leading to a loss of hydraulic pressure, which makes steering harder.
- Clogged Steering Valves: If the hydraulic steering valves get clogged with debris or sludge, they can prevent proper fluid flow, leading to poor steering performance.
Vibration in the steering wheel while operating the machine is another issue that can arise. This could be caused by:
- Worn Hydraulic Lines: If the hydraulic lines or fittings are damaged or leaking, the system can struggle to maintain the necessary pressure, resulting in erratic behavior and vibration.
- Dirty or Contaminated Hydraulic Fluid: Hydraulic fluid that is contaminated with dirt, metal shavings, or other debris can cause the hydraulic system to work inefficiently, leading to vibrations in the steering wheel.
Leaks are one of the most common and troublesome issues for the hydraulic systems on older equipment like the 580 CK. Common leak sources in the steering system include:
- Hydraulic Hoses and Fittings: Over time, the hoses and fittings that carry hydraulic fluid can degrade or crack, leading to leaks.
- Steering Cylinder Seals: The seals in the hydraulic cylinders can wear out, causing fluid to leak from the cylinder, reducing the efficiency of the steering system.
- Pump and Valve Leaks: The steering pump or control valves can develop leaks, leading to a loss of hydraulic fluid and diminished steering performance.
To resolve steering issues on the Case 580 CK, a methodical approach to troubleshooting is necessary. Here’s how to systematically address and resolve the most common steering issues:
1. Check Hydraulic Fluid Levels and Quality
The first step in troubleshooting any hydraulic steering problem is to check the hydraulic fluid levels. Ensure that the fluid is at the proper level according to the service manual specifications.
- Fluid Quality: Inspect the hydraulic fluid for contamination. If the fluid is dirty or contains debris, it should be replaced. Always use the manufacturer-recommended type of hydraulic fluid for the best performance.
Visually inspect all the hydraulic hoses and connections leading to and from the steering system. Look for any signs of wear, cracks, or leaks. If any hose is damaged, it should be replaced immediately.
- Pressure Testing: A pressure test can be performed on the hydraulic system to check for leaks or issues in the pump, valves, and cylinders. A qualified technician can perform this test to identify pressure drops in the system.
The hydraulic pump is the heart of the steering system. If the steering is heavy or unresponsive, the pump may be failing.
- Pump Testing: Use a flow meter to test the output of the hydraulic pump. If the pump is not providing the correct flow, it may need to be repaired or replaced.
- Pump Repair: If the pump is worn, replacing it with a new or refurbished unit is the best solution. In some cases, a pump overhaul kit may be sufficient to restore performance.
Steering cylinder seals are prone to wear over time, leading to fluid leakage and poor steering performance.
- Seal Replacement: If leaks are found around the steering cylinders, replacing the seals is the most effective solution. Be sure to clean the cylinder thoroughly before installing the new seals to ensure a tight fit.
If the hydraulic fluid is contaminated or dirty, cleaning and flushing the system is essential. This process involves removing the old fluid, cleaning the hydraulic components, and refilling the system with fresh fluid.
- Filter Replacement: During this process, it’s a good idea to replace any hydraulic filters, as clogged filters can further compromise the system's efficiency.
If vibration persists despite fixing leaks or replacing fluid, you may need to check the alignment of the steering components, such as the tie rods or the steering gear mechanism.
- Component Inspection: Ensure that all steering components are properly lubricated and aligned. Worn or misaligned parts can cause vibrations that make steering uncomfortable or difficult.
