 KUBOTA L2350

RECENTLY WHEN I START MY L2350 TRACTOR LARGE AMOUNTS OF BLUE SMOKE COMES OUT OF THE MUFFLER TAILPIPE. IT RUNS ROUGH FOR A LITTLE WHILE BUT EVENTUALY CLEARS UP. HOWEVER YESTERDAY WHEN I TRIED TO START IT LARGE AMOUNTS OF SMOKE CAME OUT, EMGINE WOULD TURN OVER BUT WOULD NOT RUN. OCCASIONALY IT WOULD RUN FOR A SHORT TIME AND DIE. DOES ANYONE KNOW WHAT THE PROBLEM MIGHT BE?

I'm running late today, but will get back to this unless somebody else covers it. My off the top of head comment is to be certain the smoke actually is blue. Black, white and gray smokes indicate different types of problems.

Blue is oil. The two basic sources of oil in the exhaust are down the valve guides and past the piston rings. Generally ring problems also produces blow-by out the crankcase breather. Either problem may be accompanied by low compression. However, compression getting past a valve can sometimes be detected by pressurizing a cylinder and listening for a hiss in the intake manifold. I guess an overfilled crankcase might make blue smoke.

Since this tractor has a diesel engine the smoke could be gray or white and not blue as i first indicated. I though that i had run out of fuel when the engine would not start so i went and got some fuel, also cleaned the air cleaner as it was quite dirty, but engine would still not start. After continually cranking and holding down the accelorator it seem that it wanted to start but would not contiue to run.

It could be a simple problem that the tractor did run out of fuel and got some air in the fuel or injector lines, which now need to be bled. A diesel that has air in the fuel lines usually will start and run for a few seconds and belch gray smoke. If air gets past the pump into the injector lines, a diesel may not start.

I'd start by following manual procedures for bleeding the fuel lines. If that doesn't fix it, continue with procedures for bleeding the injector lines (Care must be taken when opening injector lines because 2,000# pressure may be present even with the engine off). If a lot of air is present, bleeding procedures may have to be repeated. I'd also replace the fuel filter if there's doubt about its condition.

Hope bleeding will do the trick. If not there's a bunch of discussion about this type of trouble-shooting in the archives, and new questions usually receive useful responses.

Jay, your description of what's happening sounds much like I had happen once when I had some water in the fuel.

On poor starting and smoke. If you are getting white or grey smoke smelling very strongly of diesel, then this is called diesel "fog" and you will get it from several reasons. Sometimes it is from a fuel-flooded motor because of trying to start it when it is too cold and/or the motor not turning over fast enough and/or the compression being low. But if the engine is generally OK, and the battery is spinnning the motor at a good clip - then it is probably either water and crud in the fuel or an injector that is spurting fluid instead of spraying a mist. The cure is the same in either case. Drain the fuel, throw it away, replace with good fuel. This means draining the tank and filter housing and swabbing them both out. Add some injector cleaner to the fresh fuel. Good luck. Most diesel problems are simply fuel problems or not enough cranking speed.

In some cases of contaminated fuel with a Kubota it is easy to look at the fuel filter without removing anything and see if you have water in it. Water is heavier than fuel and oil so if to let it sit it will go to the bottom of the tank and filters for easy removal without having to toss it unless you have serious contamination. We do sometimes have to drain as Roger suggested in those conditions.
