Massey Fermec 650/660 3-Point Lift Troubleshooting

[MikePhua]

Introduction
The 3-point lift system is a crucial component of the Massey Fermec 650/660 backhoe loaders, allowing operators to easily attach and detach implements, such as plows, harrows, and other attachments. However, when the 3-point lift system stops working properly, it can lead to a significant disruption in the machine's functionality. In this article, we'll explore some common issues associated with the 3-point lift system on the Massey Fermec 650/660, potential causes of failure, and troubleshooting steps to get the system working again.
1. Common Issues with the 3-Point Lift
The 3-point lift system may experience various operational problems, including:

• Failure to Lift or Lower: The most common problem is the failure of the system to lift or lower attachments properly. The lift arms might not move, or they could become stuck in a raised position.
  
• Uneven Lifting: In some cases, the lift arms may rise unevenly, with one side of the attachment lifting higher than the other. This can create instability, especially when operating in uneven terrain.
  
• Slow or Jerky Lifting: The lifting action may be slow or jerky, which could be an indication of hydraulic issues, such as low fluid levels, air in the system, or internal leaks.
  
• Hydraulic Fluid Leaks: Leaks from the hydraulic cylinder or lines can prevent the lift system from operating correctly. Leaks can reduce pressure, causing the system to malfunction.
  
• Erratic Control: The control lever or joystick that operates the lift system may become erratic or unresponsive, making it difficult to control the attachment.
  

2. Troubleshooting the 3-Point Lift
To address these issues, follow these troubleshooting steps:

• Check Hydraulic Fluid Levels: Start by checking the hydraulic fluid levels in the system. Low fluid levels can cause the 3-point lift to malfunction. Refill with the recommended hydraulic fluid if necessary. Be sure to check for any leaks in the hydraulic lines or cylinders.
  
• Inspect for Leaks: Look for any visible leaks around the hydraulic cylinders, hoses, and fittings. If you notice any leakage, repair the affected parts, and refill the hydraulic system as needed.
  
• Examine the Hydraulic Pump: If the system is slow or jerky, the hydraulic pump may be faulty or in need of maintenance. Inspect the pump for wear or damage, and ensure that it is providing sufficient pressure to the lift system. A failing pump can lead to inconsistent performance.
  
• Check the Control Linkage: If the 3-point lift is unresponsive or jerky, inspect the control linkage. Look for any loose connections, worn parts, or obstructions that might be preventing the lever from engaging the lift system smoothly.
  
• Test the Lift Arms: Manually test the lift arms to ensure they move freely. If the arms feel stuck, there may be an issue with the hydraulic cylinder or a blockage in the hydraulic lines. Clean or repair any parts as necessary.
  
• Bleed the Hydraulic System: If air has entered the hydraulic system, it can cause the lift to perform poorly. To fix this, bleed the system to remove any trapped air. Follow the manufacturer's guidelines for proper bleeding procedures.
  
• Inspect the Relief Valve: The relief valve is a critical component in the hydraulic system that prevents excessive pressure buildup. If the relief valve is malfunctioning or set incorrectly, it could cause lifting issues. Make sure the valve is functioning correctly and replace it if needed.
  

3. Solutions to Fix 3-Point Lift Issues
Once the cause of the problem has been identified, you can implement the following solutions:

• Refill Hydraulic Fluid: If low hydraulic fluid is the issue, simply top off the fluid to the correct level. If the fluid is contaminated, it may be necessary to drain and replace it.
  
• Repair or Replace Leaking Components: For any leaks in the system, replace worn or damaged seals, hoses, and cylinders. Ensure all hydraulic components are tightly secured and leak-free.
  
• Replace the Hydraulic Pump: If the hydraulic pump is found to be faulty, replace it with a new one. A malfunctioning pump can drastically affect the performance of the 3-point lift system.
  
• Fix or Replace Control Linkage: If the control linkage is damaged or malfunctioning, repair or replace the necessary components to restore smooth control of the lift.
  
• Bleed the Hydraulic System: After removing air from the system, check the lift performance to ensure it operates correctly. This can be especially important after opening the hydraulic lines for repairs.
  
• Adjust or Replace the Relief Valve: If the relief valve is malfunctioning, adjust or replace it to ensure proper hydraulic pressure regulation.
  

4. Preventive Maintenance for the 3-Point Lift System
To avoid future issues with the 3-point lift system, regular maintenance is essential. Follow these tips to keep the system functioning smoothly:

• Regular Fluid Checks: Periodically check the hydraulic fluid levels and condition. Change the fluid as recommended by the manufacturer, and replace filters when necessary to maintain a clean and efficient hydraulic system.
  
• Inspect Hydraulic Components: Regularly inspect the hydraulic cylinders, hoses, and fittings for signs of wear or leaks. Replace damaged components before they cause more significant issues.
  
• Lubricate Moving Parts: Lubricate the lift arms, pivots, and other moving parts to prevent premature wear and ensure smooth operation.
  
• Test the System: Before each use, perform a quick test of the 3-point lift system to ensure it’s functioning correctly. If there are any signs of issues, address them immediately to prevent further damage.
  

Conclusion
Troubleshooting the 3-point lift on a Massey Fermec 650/660 backhoe loader can involve checking hydraulic fluid levels, inspecting for leaks, and ensuring that all components, including the control linkage and hydraulic pump, are functioning properly. Regular maintenance, including fluid checks, inspections, and lubrication, will help prevent future issues and ensure smooth operation of the lift system. If problems persist, it may be necessary to consult with a professional technician for further assistance.
