    If its that cheap buy it! Gently check that its free and will turn over. Then drain the diesel and refill, change the fuel filters, drain and refill oil, change filters, drain and refill coolant, all the time checking for oil and water where it shouldn't be. Maybe squirt a little oil down the bores (a little, not much, just so the cylinder walls aren't dry) Turn over again , bleeding the fuel system .
    Then try firing it up.

    turn it over just to feel for major drag esp. when you first start - if you feel rough drag it might mean the cylinder bores got rusty... is the exhaust stack shield functioning (closed) ?

    if it felt smooth for a revolution or two then i would try to fire that pig...
    a puddle of diesel isnt likley to ignite turning over slowly, or even fastly by hand, you need to turn pretty fast to raise the temp by compression enough to light even the atomised spray.

    Im in the buy it and see how it works out camp, hook up a battery and see how it goes

    I would buy it in a heartbeat! How many CFM is the compressor supposed to be? At 300 or 400 hp it must be in the 600cfm range.

    X2 on this. We have an old excavator that is contaminated and went through the whole fuel system to get it cleaned out. I would suggest that if you can start it from an auxiliary tank that has known clean fuel in it. It would also not hurt to pour in a bottle of 2 cycle oil mix in the fuel if it is an older engine designed to run on high sulfur fuel. The lube is for the injection pump and the injectors.

    no neat sig line

    Guess you haven't seen the Russian videos of WW2 tanks sitting on memorials in small towns being fired up
    after 60 yrs and driven off.

    This lump of iron will bring you nothing but headache and heartbreak. Best to send it as far away as you can, my place for instance!

    Check the pump for water and if equiped with a hand pump pump up pressure. 300-400hp diesel it must be somewhere around 10-15l in size. Not easy to hand crank but you should be able to start it. At the end of the day, if it has anything resonable as far as engine goes. You may be able to part it out even if it is not worth fixing.

    We had a few "dead" garbage wagons in our fleet, out in the back 40. The engines were all tired, but were running when we parked them. When we had to vacate that leased property, We got all of them to fire up fairly easy. One had been there 6 years. Had Cat, Cummins and Green Grenade engines. This was 10 years ago, or so, before ultra low sulfur diesel or any of the bio blends. I have no clue how the modern fuels would affect corrosion or rust issues in the fuel system. Also, these were mechanical fuel systems. Storage issues with electronic engine controls are an unknown for me. I'd have to guess that as long as the engine wiring, sensors, and ECU stayed dry you should be fine.

    We just powered up a 200kw Perkins diesel generator that has been sitting outside since 2013. New battery, checked everything external, cranked it over a few times and vaarooom... big cloud of smoke and it was purring. Old gas too.

    I start and drive our 86 6.9 diesel about once every 3 years or so. The fuel in it must be 10 years old or more. I should maybe change that next time I bring it home.

  • Diesel that has been sitting 4 years - what could go wrong?

    famous last words eh, what could go wrong?

    I'm looking at a diesel powered compressor. Its a Deere that has sat outside and not run for 4 years. Its enclosed so is somewhat protected from the rain/snow, but it hasn't been in a heated building either. Its big, getting exact details, but like 300-400 hp. on one hand it might be expensive to fix, otoh, the opportunity on an "as is where is basis" is at 10 cents on the dollar compared to them running.

    Just wondering how the guys familiar with diesels would react to that - don't touch it with a 10 foot pole....or if you do a b and c no big deal. The owner says it was running when he parked it (he ended up with it when a tenant went belly up). I don't know him, but he's reputable enough around town I'm inclined to believe him.

    Thanks for any insight
