Draining Water from the Fuel Tank of a Case 1845C Skid Steer: A Comprehensive Guide

[MikePhua]

Introduction
Water contamination in diesel fuel is a common issue that can lead to engine misfires, corrosion, and reduced performance. For owners of the Case 1845C skid steer, addressing this problem promptly is crucial to maintain optimal engine function. This guide provides detailed instructions on how to drain water from the fuel tank, along with preventive measures and maintenance tips.
Understanding the Fuel System
The Case 1845C is equipped with a diesel engine that relies on a clean and water-free fuel system for efficient operation. Water can enter the fuel system through condensation, contaminated fuel, or leaks. If left unchecked, water accumulation can damage fuel injectors, clog filters, and cause engine stalling.
Draining Water from the Fuel Tank
To remove water from the fuel tank of the Case 1845C, follow these steps:

1. Locate the Drain Plug: On the right side of the machine, beneath the fuel tank, you'll find a welded drain plug. This is typically a ½-inch square drive plug designed for easy removal.
   
2. Prepare for Fuel Spill: Before removing the plug, ensure the machine has minimal fuel to prevent excessive spillage. It's advisable to perform this procedure when the fuel tank is low.
   
3. Remove the Drain Plug: Using a ½-inch square drive tool, carefully remove the drain plug. Allow any accumulated water to drain out completely.
   
4. Inspect the Drainage: If only water drains out, it indicates significant water contamination. If fuel follows, the contamination level is lower.
   
5. Flush the Tank: After draining, consider flushing the tank with clean diesel fuel to remove any residual water and contaminants.
   
6. Replace the Drain Plug: Once the tank is clear, securely replace the drain plug to prevent leaks.
   

Maintaining the Fuel System
Regular maintenance is essential to prevent water contamination in the fuel system:

• Drain Water Separators: The Case 1845C is equipped with a fuel/water separator filter. Regularly drain any accumulated water from this filter to prevent clogging and ensure efficient fuel flow.
  
• Use Fuel Additives: Incorporate fuel additives that prevent water accumulation and microbial growth in the fuel system.
  
• Monitor Fuel Quality: Always source fuel from reputable suppliers and avoid purchasing from stations with questionable fuel quality.
  
• Inspect Fuel Lines: Regularly check fuel lines for leaks or cracks that could allow water ingress.
  

Preventive Measures
Implementing preventive measures can significantly reduce the risk of water contamination:

• Install Fuel Tank Vents: Ensure the fuel tank has proper ventilation to prevent condensation buildup.
  
• Store Equipment Properly: When not in use, store the skid steer in a dry, sheltered environment to minimize exposure to moisture.
  
• Regularly Run the Engine: Operating the engine regularly helps to burn off any accumulated moisture in the fuel system.
  

Conclusion
Properly draining water from the fuel tank and maintaining the fuel system are vital practices for ensuring the longevity and performance of your Case 1845C skid steer. By following the outlined procedures and implementing preventive measures, you can safeguard your equipment against the detrimental effects of water contamination.
