555A Ford Backhoe Lubrication Guide

[MikePhua]

Overview of the 555A Backhoe
The Ford 555A backhoe, produced in the late 1970s and early 1980s, is a versatile construction machine widely used for digging, trenching, and material handling. It combines a front loader and rear backhoe on a compact chassis, making it suitable for both urban and rural construction projects. Its reliability and ease of maintenance contributed to its popularity, with thousands sold across North America and Europe.
Engine and Hydraulic System
The 555A is equipped with a diesel engine, typically producing between 70 and 80 horsepower. Its hydraulic system powers the boom, dipper, and bucket, providing smooth and precise control. Proper lubrication is essential to prevent wear, maintain efficiency, and extend the life of both the engine and hydraulic components.
Recommended Lubricants

• Engine Oil:
  • SAE 15W-40 or 10W-30 diesel engine oil, depending on climate.
    
  • Change every 250–300 hours or according to the manufacturer’s schedule.
    
• Hydraulic Oil:
  • ISO VG 46 hydraulic oil is recommended for the backhoe and loader circuits.
    
  • Ensure oil cleanliness to avoid contamination and premature pump wear.
    
• Transmission and Differential Oil:
  • SAE 80W-90 gear oil for the rear axle, differential, and transmission.
    
  • Regularly inspect for metal particles indicating excessive wear.
    
• Grease Points:
  • Use lithium-based multi-purpose grease for all pivot points, pins, and bushings.
    
  • Grease daily under heavy usage to prevent scoring and corrosion.
    

Lubrication Maintenance Practices

• Daily Checks:
  • Inspect engine oil, hydraulic oil, and coolant levels before operation.
    
  • Look for leaks in hoses, fittings, and seals.
    
• Weekly Maintenance:
  • Grease all boom, dipper, and bucket pivot points.
    
  • Check the loader and backhoe cylinder rods for nicks or scratches.
    
• Monthly or Periodic Maintenance:
  • Replace hydraulic filters to maintain flow and prevent contamination.
    
  • Drain and refill gear oil in the transmission and differential as needed.
    

Tips for Optimal Longevity

• Avoid mixing different brands or types of oil, especially in hydraulics.
  
• Warm up the engine before heavy operation in cold climates to allow oil circulation.
  
• Use high-quality filters and lubricants to minimize downtime and repair costs.
  
• Maintain a log of oil changes and greasing intervals to ensure consistent maintenance.
  

Conclusion
Proper lubrication is a cornerstone of maintaining the Ford 555A backhoe. By following recommended oil types, greasing schedules, and routine inspections, operators can maximize performance, reduce wear, and extend the operational life of the machine. Attention to lubrication not only prevents mechanical failures but also enhances productivity and safety on the job site.
