This weekend my 4 year old Kubota M6800 began to lose power and then shut down, and would not restart. It seemed fuel related so I removed the water separator screen/filter and found it packed with what looked like red clay or sediment. I just had a major service in November and the hours are minimal. Since that service (when they changed all fluids and filters, or so they said) I have used maybe 4 or 5 tanks of diesel, always carried in 5 gallon containers. After I cleaned everything and bled the line of air, it runs fine. Where did all of this come from? Surely the fuel was not that dirty. I wonder what composed the muddy looking sediment. I also wonder if my dealer did not really service it properly. I must admit that I have not bled any water from the separator since that service. Could water build up cause this sediment? How often do you guys have to clean this filter screen and bleed any water?
