The Ford 555A backhoe loader is a versatile machine, widely used in construction, landscaping, and excavation projects. One of the key components of the machine’s functionality is the steering system, which relies on hydraulic steering cylinders. Over time, these cylinders can experience issues, leading to steering difficulties or a complete failure of the steering mechanism. This article will discuss the common problems related to the Ford 555A steering cylinders, how to diagnose them, and steps for repair or replacement.
Understanding the Steering System on the Ford 555A
The Ford 555A backhoe loader is equipped with a hydraulic steering system, which uses hydraulic cylinders to control the movement of the front wheels. This system allows for smooth, effortless turning, which is crucial for maneuvering the heavy machine in tight spaces. The steering cylinders are connected to the steering control valve and receive pressurized hydraulic fluid to move the wheels when the operator turns the steering wheel.
There are typically two hydraulic steering cylinders on the Ford 555A: one for each front wheel. These cylinders are responsible for transferring the hydraulic pressure to the steering linkage, allowing the machine to pivot efficiently.
Common Problems with Steering Cylinders
Steering cylinder issues on the Ford 555A can be attributed to several factors, from worn-out seals to damaged internal components. Below are the most common problems that users might encounter:
To properly diagnose steering cylinder issues on the Ford 555A, it’s important to follow a systematic approach. Here’s how you can do it:
Once the problem has been diagnosed, the next step is deciding whether to repair or replace the steering cylinders. Here’s a breakdown of both options:
The Ford 555A is a reliable and robust backhoe loader, but like all machines, it requires regular maintenance to keep it running smoothly. Steering cylinder issues are among the most common problems faced by operators, but with proper diagnosis and timely repairs, these problems can be resolved efficiently. Whether you choose to repair the cylinders or replace them entirely, maintaining the hydraulic system and steering components will ensure that your Ford 555A remains a powerful, efficient tool for years to come.

Common Problems with Steering Cylinders
Steering cylinder issues on the Ford 555A can be attributed to several factors, from worn-out seals to damaged internal components. Below are the most common problems that users might encounter:
- Leaking Hydraulic Fluid
- A common issue with hydraulic steering cylinders is fluid leakage. Leaking can occur due to worn seals, damaged hoses, or cracks in the cylinder body. If the hydraulic fluid is leaking, it can cause the steering system to lose pressure, making it difficult or impossible to steer the machine.
- Symptoms: Low fluid levels, visible oil puddles around the cylinders, and reduced steering effectiveness.
- A common issue with hydraulic steering cylinders is fluid leakage. Leaking can occur due to worn seals, damaged hoses, or cracks in the cylinder body. If the hydraulic fluid is leaking, it can cause the steering system to lose pressure, making it difficult or impossible to steer the machine.
- Stiff or Unresponsive Steering
- If the steering cylinders are not functioning properly, the steering may become stiff or unresponsive. This can be caused by contamination in the hydraulic fluid, air trapped in the system, or internal damage to the cylinders.
- Symptoms: Difficulty in turning the steering wheel, especially under load or at low speeds, and erratic wheel movement.
- If the steering cylinders are not functioning properly, the steering may become stiff or unresponsive. This can be caused by contamination in the hydraulic fluid, air trapped in the system, or internal damage to the cylinders.
- Uneven Steering
- Sometimes, one side of the steering system may not respond as well as the other, leading to uneven or inconsistent steering. This can be caused by issues such as one steering cylinder failing or becoming clogged.
- Symptoms: The machine turns more easily in one direction than the other, or the steering is slower on one side.
- Sometimes, one side of the steering system may not respond as well as the other, leading to uneven or inconsistent steering. This can be caused by issues such as one steering cylinder failing or becoming clogged.
- Loss of Hydraulic Pressure
- The steering system relies on hydraulic pressure to operate the cylinders. If there is a loss of pressure, it could be due to a problem with the hydraulic pump, steering valve, or the steering cylinders themselves.
- Symptoms: The steering wheel feels loose, or the wheels do not turn properly when the steering wheel is turned.
- The steering system relies on hydraulic pressure to operate the cylinders. If there is a loss of pressure, it could be due to a problem with the hydraulic pump, steering valve, or the steering cylinders themselves.
To properly diagnose steering cylinder issues on the Ford 555A, it’s important to follow a systematic approach. Here’s how you can do it:
- Check for Leaks
- Inspect the cylinders, hoses, and seals for visible signs of hydraulic fluid leakage. If the leak is at the cylinder seals, it may be necessary to replace the seals or, in some cases, the entire cylinder.

- Inspect Hydraulic Fluid Levels
- Low hydraulic fluid can be a sign of leaks or improper fluid levels. Make sure to check the fluid reservoir and ensure it is at the correct level. If the fluid is low, top it off and monitor the system for any changes.

- Test the Steering Function
- With the machine running, check the steering system’s responsiveness. If the steering is stiff or unresponsive, check for air in the hydraulic system. To remove air, you may need to bleed the system.

- Check the Pump and Valve
- If the steering is still problematic, inspect the hydraulic pump and the steering control valve. Low pressure from the pump or a malfunctioning valve can prevent the system from operating correctly.
- If the steering is still problematic, inspect the hydraulic pump and the steering control valve. Low pressure from the pump or a malfunctioning valve can prevent the system from operating correctly.
- Examine the Steering Cylinders
- If all else checks out, the issue may lie within the steering cylinders themselves. Inspect the cylinders for internal damage or wear. A common sign of internal damage is a noticeable decrease in steering power or uneven performance.

Once the problem has been diagnosed, the next step is deciding whether to repair or replace the steering cylinders. Here’s a breakdown of both options:
- Repairing the Cylinders
- Seal Replacement: If the problem is due to leaking seals, replacing the seals may be sufficient to restore proper function. This process involves disassembling the cylinder, removing the old seals, and installing new ones.
- Cylinder Hone and Bore: If there is minor scoring or damage to the cylinder bore, it can often be honed to smooth out the surface. This is an effective repair for minor wear and tear.
- Rebuild the Cylinder: If the cylinder has significant internal damage, a full rebuild may be necessary. This involves replacing damaged components such as the piston, rod, or seals and reassembling the cylinder.
- Seal Replacement: If the problem is due to leaking seals, replacing the seals may be sufficient to restore proper function. This process involves disassembling the cylinder, removing the old seals, and installing new ones.
- Replacing the Steering Cylinders
- If the cylinders are beyond repair, replacement may be the best option. New cylinders for the Ford 555A are available from authorized dealers or aftermarket suppliers. When replacing the cylinders, it’s important to ensure that the new cylinders are of the same size and specifications to ensure compatibility.
- Installation: Replacing the steering cylinders involves removing the old cylinders from the machine, disconnecting the hydraulic hoses, and installing the new cylinders in place. Proper torque specifications should be followed when tightening bolts to avoid any issues with the new installation.
