One of our test machines at work recently fell ill..... It is our test machine that we install prototype equipment on. I believe it was the one with the 275hp cummins but I'm not sure. Anyway, it started missing and running poorly...lots of smoke. The engine was under warrantee so Cummins came to check it out. I have heard a few different stories, but one guy told me it dropped a valve...one guy said it was ALL of the injectors that failed...one guy said a rockerarm came apart... So at this point I really don't know. I do know fuel samples were taken, the engine was pulled, the top end was rebuilt along with new injectors and the engine was reinstalled. The same fuel that was in it previously was put back in it. The machine was ran one hour and started missing again....but only under load at first. It would idle and high idle fine.....load the engine and it was start missing. Then the missing got worse till it wouldn't idle up at all and at low idle the smoke was black as coal.
FYI, this piece of equipment is hydrostatically driven. The engine either operates at low idle or high idle - 2400rpm.
Cummins came back again...tore the top end down and found the crank and cam position sensors bad and claimed all 6 injectors were bad as well. This time they blamed it on the fuel. The injectors were replaced as well as the crank/cam sensors and god knows what else. Fuel samples were sent off again. New fuel was put in the machine this time. We have about 20 hours on it and no issues.
So there sits the fuel in two 55 gal barrels. Work doesn't want it. They said I could have it....
So, I'm concerned it is contaminated ....sugar? That was the techs theory....
Although, Cummins did pay for all of the repairs, even the second time when they first insisted it was a fuel related issue. I haven't seen the fuel reports yet.
I think I'm going to snag it while the gettin' is good and wait till I hear something back from the fuel report.
If it is bad, what can I do with it ?
