Holy crap, if 3 of my 6 machines id bought just this yr had burned I dont think Id get near the other 3... How much damaged to the 2 that didnt go to the ground? What's in the around the fuel tank that might possible be starting them or is there just enough engine heat in the area? Whats been your dealer/case response?
Just about burnt up a 7010 yesterday was burning under the radiator and air screen melted some plastic. I think the fires are starting on the turbo manifold area and then spreading across the machine. Pretty stupid fuel tank design with all the channels in there that dust can settle in and very hard to get cleaned. Seems to be when dust is sticking blow off every 1 hr to 1 1/2. we put 15 gallons water on back. Also there is a cover above fuel tank make sure take these bolts out so youcan clean this area out. If anyone else has ideas to help fire problems let me know
That is high. I know that about 40-50 percent of the first two years' 8010's had the same problem, too. That was way higher than any other combine, until the 70 Series John Deeres were introduced. It was about that, for the first few hundred 70's. In 37 years of observation, I've never seen such a high percentage of fires, period. My theory is that plastic holds/generates more static; add to this, the fact that today's combines are all full of electronics, more wiring than a three bedroom house and a lot more hydraulics than just 25 years ago.
Why is it that combine manufacturers don't even have recalls like the auto makers do? I think it was only a rather small number of Ford Pintos that actually burned, but the recall was fast and effective. At the same time, at least 4 out of 5 or even 9 of 10 Model 815's [International Harvester] with those dual exhaust stacks, burned during their first three years. IHC made no recall on those.
they don't have "recalls" per se, but they do have mandatory programs to fix issues that are deemed worthy (whatever that means). Dealers get a list of machine serial numbers that are affected, and are allotted x amount of labor dollars (with parts provided) to fix the problem.
Not something that hits the front page of the NY Times, but it is relatively effective in most cases.
There are antistatic kits available if that is what is starting the fires. Think they work with the rotary screen and the rad fan. You harvesting a high oil crop of some sort like sunflowers? If conditions are very dirty blow the alternator out regularly, could be the cause of your problem.
Combines 30 years ago were lucky to have over 200 horse power, and had ZERO emissions. There are now combines with over 500 horsepower in the fields and that takes a serious amount of fuel to acheive that. If you pump fuel to an engine you are going to generate a lot of exhaust heat and when you work in an invrioment that is nothing but dust something is bound to happen some time.
Then you add to the fact the emissions requirements all manufactures are suppose to deal with and that compounds the problem. They have raised cylinder temps to counter act NOx emissions and once again that raises exhaust temps.
Customers demand that these machines do more per hour so manufactures of all colors have answered that demand and this is what we have to work with. There are static kits that that help reduce static, but exhaust temps have to be lowered which would require a major drop in horse power and customers would loose productivity or eliminate dust and we know that is not going to happen.
You're so right, Bigblock. Our combines see more pressure and workload than ever before.
However, we also have the technology of automatic fire suppression, such as used in aircraft. It needs to be installed at the factory.
