My dad's 240 Massey Ferguson set for about two years without being started. I was able to get it started without changing fuel filters. I did change the air filters. I have run it about 10 hours since starting. It starts easy and has good power. It makes a lot of white smoke when first started and then gets down to a light haze but never clears up when you run it. If you idle it for a while it will increase the white smoke. What might be the problem and are there any adjustments I could make? I am a decent mechanic on gas but never worked on diesels.

Thanks Bill Perry

I think Royin UK has hit the nail on the head. I'd change the fuel filters. I'd also stick a bottle of Stanadyne High Performace Fuel Additive in it. No, I don't sell Stanadyne and don't feel comfortable recommending any product, but this stuff has made a believer out of me. It will clean the gunk out of your injection pump and injectors.

I agree with saltherring. I once had a Case 801B that sat for about 2 years also(gift). I drained the fuel tank, changed all fuel filters, let water and sediment settle out of the drained fuel then poured off the fuel while leaving the dreggs. I poured the old filtered fuel back into the tank with some diesel injector cleaner, installed a good battery, turned the key and it started right up. Smoked-whew! It took about a day for it to clear up. White exhaust smoke from a diesel engine indicates unburned fuel, especially in cold weather. I would'nt get excited, just use the tractor after cleaning the fuel system and it should clear up.

If it had been stood all that while I would change the fuel filters anyway. They could have a quite a bit of grit/ and or moisture in them by now.

bill, you could have a sticky cold start solenoid or a sticky injector nozzle. remove fuel pipe from cold start located on intake manifold and test run, if no improvement put half a quart of auto trans fluid in fuel tank and try, last of all i would replace fuel filters.if no better i would remove injectors and re con.hope this helps! cheers.

fellas, if the fuel filters are choked, the engine would starve for fuel and cut out. it still has heaps of power as stated by the owner, havent seen a perkins yet that will perform well with choked fuel filters. i agree fuel conditioners work well, so do you fit new filters, add conditioner to fuel tank to clean out the gunk, where does it end up?, do you then change the fuel filters again,? the owner stated he used the tractor for 10hrs so surely he had to refuel with fresh fuel in that time. its only my opinion anyways. good luck!!!

I ran a full tank thru it this past week. I assume white smoke means too much fuel for a given power setting. It is worse idling but never clears up completely even when pulling a double gang disk. A slight haze comes from the exhaust pipe. It does run strong. It also starts easily, turning over maybe one or two times and is running. Maybe I need to run some conditioner thru it. When I first started it about two years ago I did run some conditioner thru it and maybe it cleared it up a little. It seems to be worse now than it was then. I will look at all the items you pointed out on my next trip to the farm.I don't see a lot of cold start stuff on it to check out. Maybe the injectors are just gunked up and won't close at low rpm. However I have never experienced a rough idle indicating they aren't misting properly. I did have a slight leak on the fuel pump at the diaphragm and tighten some screws to eliminate that as a problem. Anything else you can think of I will look at.

bill, a word of warning, some and i quote, some ,fuel conditioners are very highly corrosive to metal components if left in fuel systems for extended periods. a very popular japanese auto manufacturer have warnings on their fuel cond. bottle to state this. if you use it only leave it in the system for the amount you are going to use immediately. do not leave it in the system for extended periods. cheers, sibby.

I think I will just put the auto transmission fuel in. No problem with corrosion, I assume

iwould suggest changing the fuel filters.fill it with fresh fuel and add a quart of tranny fluid to the fuel.find a project to make it work to maximum output,get it warmed right up and work it hard.if it still does this after areally good work out,you may have to look at new injectors.from sitting,they made have been damaged from moisture coolecting in the cylinders.mother nature has no mercy on diesel engines.

no problems with corrosion with a.t.f. Bill. a.t.f. contains anti oxidents, which combat corrosion! cheers.
