The Case 580C and Its Mechanical Legacy
The Case 580C Construction King was introduced in the late 1970s as part of J.I. Case’s renowned backhoe-loader series. With a 3-cylinder diesel engine and mechanical fuel injection, the 580C became a staple on job sites across North America. Its simplicity and ruggedness made it a favorite among contractors and municipalities. By the early 1980s, Case had sold tens of thousands of these machines, many of which remain in service today due to their rebuildable components and widespread parts availability.
Symptoms of Intermittent Shutdown
A common issue with aging 580C units is that the engine starts easily, runs for a few minutes, and then stalls. After restarting, the machine repeats the cycle—running briefly before shutting down again. This behavior often mimics fuel starvation but can persist even after replacing filters and confirming fuel flow.
Initial Checks and Misleading Clues

• Fuel Filters and Lines: Replacing both primary and secondary filters is a logical first step. If the engine still stalls, check for blockages in the fuel lines, including the pickup tube inside the tank and the return line to the tank.
  
• Air Intake: Removing the air filter can rule out intake restriction, but in most cases, this has no effect on the stalling issue.
  
• Fuel Cap Venting: A clogged fuel cap vent can create a vacuum in the tank, restricting fuel flow. Loosening or removing the cap during operation can help diagnose this, though it’s often not the root cause.
  

• Flex Ring: A plastic ring inside the injection pump that connects the governor weight cage to the pump’s drive mechanism. Over time, it breaks down and sheds debris.
  
• Check Valve: A one-way valve that allows fuel to exit the pump but prevents backflow. When clogged, it traps pressure inside the pump.
  
• Governor Weight Cage: A rotating assembly inside the injection pump that regulates fuel delivery based on engine speed.
  

• Disassembling the pump and removing all debris.
  
• Replacing the flex ring with a modern one-piece weight cage that eliminates the original failure point.
  
• Reassembling and calibrating the pump using specialized tools and torque specifications.
  

• Timing the Pump: Before removal, align the timing marks inside the pump by rotating the engine until the stationary and rotating lines align. This ensures proper reinstallation.
  
• Torque Specs:
  • End Plate: 30–35 in-lbs
    
  • Delivery Valve: 90 in-lbs
    
  • Cam Screw: 300–350 in-lbs (requires special tool)
    
• Rebuild vs. Replace: A rebuilt pump typically costs $1,100–$2,000 with core exchange. DIY rebuilds are possible but require precision and experience.
