6v92 Detroit Diesel Firetruck, what blew up?
Автокөліктер мен көлік құралдары
This firetruck was bought almost 4 years ago. It burnt a tone of coolant when we drove it. And then it died on one fateful day, completely seizing the engine. Now we need to repair it. The Fire Department had let it sit and idle for around 10 hours. Which had caused...what ever happened to it. So we are starting the process of repairing this big old beauty!

At 15:29 it is supposed to say 1/8th inches not 1/4 I just didn't feel like waiting 5 hours to fix it and re-upload lol
Still my all time favorite video from you guys is when you had to cold start your air compressor when you were mounting some military tires. 😂🙃

Nah, algorithm kind of bits us for a while oh well 🤷
My guess is some enginerd forgot to enage the engine cooler valve that keeps it cool while pumping and achieved maximum toast. If you want some advice for running the pump I'm not the greatest expert at it but I've learned quite abit from my guys at the fire station jut no real experience yet although older pumps are more my specialty. Just ask anytime and I can awnser questions.

sweet thanks! It is unfortunate about this engine though, she really was super clean inside. Fire department thought it blew a head gasket (head ring/seal thing) and didn't want to fix it. It blew up on us a couple days after purchase haha. Although, we now think it may have been the After cooler that was dumping coolant into the engine. Which caused the subsequent sizing of the engine.

@@ThisGuysStuffandStuff The aftercooler leaking would make sense, i see those corrode or get pinholes pretty easy, i think it's block and the copper in the cooler that have dissimilar metal corrosion. There should be a heat exchanger coming from the pump to the radiator system to check at too, where at not sure on this truck. If you ever try pump operations let me know before you do and I can give you a basic guide, those seals are expensive and can be burnt up even if you have water if you don't do it right. There should be a little plaqard in the truck that has the oils and coolants and weights all neat and labeled for the pump, trans, engine, radiators, axles, etc. Ours do atleast in our fire station. I'm not detroit mechanic by any means but I have the 92 series shop manual and was using it for a project quite abit and I know my way around a fire truck mechanically pretty ok. One thing to note is I believe the fire trucks were raised 300-400rpm or so on the governer compared to normal spec. It would usually equal 2300-2400 i think for the 6v92, don't quote me on that as i think it was dealers choice but quite alot of fire forums mention it might want to check there when it comes for the no load governer rpm setting. I think it had to do with getting the right pump RPM or possibly higher output power for response not sure.
