Ford 655C Power Steering Hose Replacement: A Step-by-Step Guide

[MikePhua]

Introduction: Importance of a Functional Power Steering System
The Ford 655C tractor loader, like many heavy-duty machines, relies on a well-functioning power steering system for smooth and efficient operation. A common issue that can arise with the system is a damaged or leaking power steering hose. A faulty hose can cause a loss of steering fluid, resulting in difficulty steering or, in some cases, a complete failure of the power steering system. This guide outlines the process of diagnosing and replacing the power steering hose on a Ford 655C to keep the machine operating at its best.
Identifying a Faulty Power Steering Hose

1. Signs of Power Steering Hose Issues
   

The power steering hose in a Ford 655C can wear out over time due to factors like exposure to heat, pressure, and vibration. A damaged hose can lead to a loss of hydraulic fluid, which in turn causes poor steering performance. Below are signs that your power steering hose may need replacing:

• Leaking Fluid: Visible power steering fluid around the hose or under the machine.
  
• Difficulty Steering: Increased difficulty or stiffness when turning the steering wheel, especially when the machine is idling or under low speed.
  
• Whining Noise: Unusual noises from the power steering pump, often caused by low fluid levels due to a hose leak.
  
• Fluid Level Drops: A noticeable drop in the power steering fluid reservoir level.
  

1. Locating the Faulty Hose
   

Before replacing the hose, inspect the system to locate the exact source of the leak. The power steering hoses are usually made of rubber or braided steel and can deteriorate at the connection points, causing leaks. Check both the high-pressure and return hoses, as either one could be the source of the issue.
Steps to Replace the Power Steering Hose

1. Preparation and Safety Measures
   

Before starting the replacement process, ensure the tractor is turned off, and the engine has cooled down. Power steering systems are under high pressure, so working on them requires caution. Gather the necessary tools and replacement parts before beginning the job:

• New power steering hose
  
• Wrenches (adjustable and socket wrenches)
  
• Jack and jack stands (if necessary for extra clearance)
  
• Fluid catch pan (to collect any fluid that may spill)
  
• New power steering fluid (specific to the Ford 655C)
  

1. Disconnect the Battery
   

For safety reasons, disconnect the tractor’s battery before working on any hydraulic or steering components. This will prevent accidental electric shocks or shorts during the process.

1. Locate and Remove the Old Hose
   

The power steering system consists of two hoses: a high-pressure hose and a low-pressure return hose. Start by locating the hoses attached to the power steering pump and steering valve.

• Remove the Pressure Hose: Use a wrench to loosen and remove the high-pressure hose from the pump and steering valve. Be ready for some hydraulic fluid to spill out.
  
• Remove the Return Hose: Loosen the connection of the low-pressure return hose from the steering valve, and carefully remove it from the system. Once both hoses are disconnected, remove the old hoses completely from the tractor.
  

1. Install the New Hose
   

• Fit the New Pressure Hose: Take the new high-pressure hose and connect it to the power steering pump and the steering valve. Ensure that the fittings are properly aligned and secure them tightly with a wrench.
  
• Attach the Return Hose: Connect the new low-pressure return hose to the steering valve and secure the fittings.
  

1. Check for Proper Alignment and Fit
   

Before tightening everything fully, double-check that both hoses are properly routed and free from any sharp bends. The hoses should not be in contact with any hot or moving components. Once everything is aligned, tighten the connections securely using a wrench.

1. Refill the Power Steering Fluid
   

Once the new hoses are installed, refill the power steering fluid reservoir with the correct type of fluid. Ensure that the fluid level is appropriate and check the manufacturer’s specifications for the proper fluid to use.
Testing the New Power Steering Hose

1. Start the Engine
   

With the new hoses installed and the fluid topped up, reconnect the tractor’s battery and start the engine. Check for any signs of leaks around the hose connections.

1. Test Steering Operation
   

Turn the steering wheel from lock to lock while the engine is running to ensure the system is pressurizing properly. Pay attention to any abnormal sounds or resistance. If the steering feels smooth and the fluid remains at the correct level without leaks, the replacement is successful.

1. Check for Leaks Again
   

After operating the machine for a short period, recheck all connections to ensure there are no leaks. If any leaks are detected, tighten the hose connections or inspect the hose for damage.
Preventing Future Power Steering Hose Issues

1. Regular Inspections
   

Regularly check the power steering hoses for signs of wear or leaks. Look for cracks, bulges, or abrasions in the hoses that could lead to failure. Early detection of these issues can prevent unexpected breakdowns.

1. Proper Fluid Maintenance
   

Ensure that the power steering fluid is changed regularly and topped up as needed. Contaminated or old fluid can cause damage to the power steering components, including the hoses.

1. Avoid Overloading the Tractor
   

Excessive pressure on the power steering system can cause damage to the hoses. Avoid overloading the tractor and be mindful of the machine’s limitations to prevent undue stress on the steering components.
Conclusion: Maintaining Your Ford 655C Power Steering System
Replacing a faulty power steering hose on the Ford 655C is a relatively straightforward task that can greatly improve the machine’s steering performance. Regular maintenance, including checking hoses for wear, ensuring proper fluid levels, and avoiding overloading, will keep the power steering system functioning efficiently for the long term. If you're unsure or uncomfortable performing the replacement yourself, consider seeking help from a professional mechanic to ensure the job is done correctly and safely.
