Diesel system contamination can cause serious problems in any engine, however within the earthmoving industry today’s high-performance, low-emissions models are especially vulnerable to contaminants.
Contaminants can cause critical components to wear prematurely, resulting in reduced engine power, increased fuel consumption, and increased likelihood of costly repairs and production downtime.
Job sites can reduce expensive diesel contamination by ensuring each stage of the fuel transfer process has well maintained service equipment and strict procedures to ensure cleanliness when it enters your equipment.
Minimising Diesel Contamination Tips
- Regularly drain and flush all fuel storage containers, including tankers and fixed tanks, removing sediments that can easily enter the fuel stream;
- Ensure all injectors, lines, water separators, filters and tank caps are regularly maintained and cleaned prior to fueling;
- Conduct regular maintenance on all hoses, lines, filters, screens, gaskets and seals in your fuel storage and transfer equipment;
- Provide service technicians with training on proper maintenance and repair processes;
- Ensure all fuel transfer equipment has in-line filters and water separators installed;
- Don’t open new filter packaging until they are being installed;
- Use a high-pressure water wash to clean the engine and powertrain before opening it for repairs;
- Perform a visual inspection, for any leaking diesel or worn gaskets and replace immediately;
- Ensure diesel tank vent tubes are open and functioning correctly;
- Never run equipment to the point where the diesel tank is completely empty;
- Never use old diesel.
