M8560 Engine dies frequently

[art]

I go with the crap in the tank! Many of the fittings going in are able to drop plastic into the tank and then clog fuel outlets from the tank. They might change the frequency depending on the amount of fuel in the tank! We do see it from time to time on newer tractors. Another thing we see from time to time is someone put gas in the tank. This to will cause problems on different slopes.

I had an issue on a M7040. I spend days and even tried a new fuel pump after draining the fuel, replacing filter, taking of the fuel and checking for vaccuum, etc. Tractor would run fine for a while then after being under load would start to sputter then die. Let it sit a while and it would crank and run for a while then eventually die. Check the 90deg fitting and shutoff valve on the fuel water separator. Take the separator off and take the shutoff valve apart. There is plastic cylinder that is the internal part of the valve. This was packed with trash and eventually starved the engine of fuel when under load. At idle it would run for a while, but high fuel demand for several minutes and it would start to starve.

I had heard of this issue but bc the tractor would run fine for a little while, I thought it couldn't be a blocked line. I went as far as talking a 5 gallon can an stapling to the hood and feeding the injector pump directly to rule out an injector pump issue. I kept working my way back in the system adding components until the separator was identified. Wish I would have just checked this first.

Thank you sir. There was a bug stuck on the inside of the water separator as u described. I also drained the tank and put fuel back in with a metal screen just in case anything else was inside. Runs great now. Frustrating for sure..

Wow. Thanks for posting the fix. I am really careful with my fuel on these new tractors. I bought a Mr. Funnel and use it religiously. Anytime my tractor fuel cap comes off the funnel goes in it. Many times clean fueling conditions are not ideal especially when I have to use the 5 gall can.
