If you are managing a fleet of heavy machinery, maintaining engine health starts with clean fuel. The 600-311-9731 fuel water separator (also known as 6003119731) is a critical component for Komatsu 6D102 and SAA6D107E engines. Designed to remove contaminants and water before they reach your fuel injectors, this filter ensures your excavator maintains peak performance even in harsh construction environments.
Our 600-311-9731 replacement is engineered to meet or exceed OEM specifications. It is primarily used in the Komatsu PC200-7, PC220-7, PC270-7, and PC300-7 series. By preventing water-induced corrosion in the fuel system, this part safeguards your high-pressure common rail system from expensive downtime.

Exact Fitment: Guaranteed compatibility with Komatsu 600-311-9731 mounting bases without modification.
Reduced Wear: Specifically prevents abrasive particles from entering the fuel pump.
Corrosion Resistance: Internal coating prevents rust within the filter canister.
Cost Efficiency: High-capacity media holds more dirt, extending intervals between changes.
Global Supply: Ready stock for PC200-7 replacement filters with international express shipping.
Technical Support: Our engineers help you verify the correct filter for your engine serial number.
This is often caused by a clogged 600-311-9731 fuel filter. If water or sediment accumulates, fuel flow is restricted. Solution: Drain the water bowl daily and replace the filter every 500 hours or when the "Fuel Filter Clogged" light appears on your monitor.
If the sensor detects water, stop the engine immediately. Locate the 6003119731 separator, open the drain valve at the bottom, and let the water flow out until clean diesel appears. If the warning persists, the filter media may be saturated and requires a full replacement.
OEM-standard tri-metal structure ensures the casing won't burst under pressure. It is trusted by repair shops and equipment fleets for its consistent micron rating and leak-free performance.
