G'day ,we have got an old pc 200-6 for occasional farm use and I cant find a fuel water separator anywhere.Where should it be ?Should have one according to the manual and everyone tells me any water in fuel will ruin injectors .Is it possible it didnt come with one , should i fit one or just change the fuel filter regularly ? The subject came up because my old diesel landcruiser just went under water up to its roof in a flooded river . thanks for any help -- mat .
should be right beside your fuel filter on the backside of the engine...if i remember correctly
Water seperator or no, most all excavators I've worked on have a drain valve on bottom of fuel tank. Some don't even require removing a cover panel, just reach through a hole in bottom panel under tank. It's easy to once a week drain water/dregs out of fuel tank using this drain valve, plus you keep this garbage from even getting to seperator or filter.
Water separators were always an option on those machines. Generally the gray market units that came into the states had them mounted in the pump compartment. They were always a problem because the operators would removed the bowls to dump them out and loose the gasket. The thing would suck air from then on. Since they were an option we could not get the gasket and would have to bypass them. ATCOEQUIP is correct about the drain valve. On the Komatsu it is directly under the tank and there is no cover to reach through or have to remove. I used to carry a cut off welding rod to bust up the sediment that would plug the valve. Unless you are working in a rain forest you can do without it with a little care.
The really poorly translated manual makes it sound like they're standard but not so. There should be a tank drain. On our 150 it's conveniently located for an occasional branch to grab and open.
