john deere 4024t injector removal

Looking for expert advise. We have John Deere based generator. After few weeks of use it died and wont start. Local mechanic couldnt get it going so we called John Deere guru, who did manage to get it going by manually flipping some start relay but now says that first guy didnt put injectors in right order resulting in rough operation.

This is the first time I hear that you need to match injectors with cylinders. Is there such a thing and whats the way to get it back in order? Back to top. If nozzles were pulled out and put back a good chance they went into different cylinders need to be re adjusted. What engine is in a ?? The engine is marked TF So there is no link between cylinder and injector, right? How hard is to re adjust those? I'm still not sure what engine you have, I've never heard of aI want to think It's along the line of abut not sure, if it is there is no match-up needed with the injectors.

After having a brand new John Deere T engine go bad on us at work we called the local John Deere service company. They worked on it for 4 days and could not get it straightend out.

Yesterday we pulled the engine and replaced it. That engine also smoked like a freight train as soon as it hit operating temperature. John Deere sent a factory tech down from Chicago to work with the two local service guys today. To their credit all three of them plus two of the sales reps from the company that we buy the engines from showed up at am sharp this morning.

They worked on the engine replacing shims under the injection pumps and finished about this morning. We fired the engine off and it ran great so we shut it down while everyone gathered their tools. After the two local techs left our assembly line forman fired the engine up again.

I was talking to my sales rep about 75 yards away and knew from the sound that something was wrong. Sure enough we see great billowing clouds of white smoke rising from the assembly line.

I mean it looks like there is a major fire inside our building!!! The John Deere tech calls the two local service guys back in and they work on it for another hour. After consulting the factory they decide there is nothing that can be done for this engine and that we would need to replace itClick to Post a New Message!

Post: The old injector is proving impossible to pull out. I have tried threading a 6in bolt into the top of the injector and using it as a sort of slide hammer with a 5 lb weight. Still no luck. I am getting very frustrated.

I would appreciate any and all suggestions. Also, I am not worried about saving the old injector - just need to get it out. Hard to Remove Injector I wish I had a magic answer for youbut I have had to resort to removing the cylinder head and driving it out with a big drift and hammer.

This ruins the injector and the pre-combustion chamber cups in the process. The slide hammer idea works sometimes, but you are going to need longer than a six inch stroke. I use a OTC silver slapper slide hammer with a custom fabricated adapter to screw into the injector. This gives you a sixteen inch stroke with a five pound hammer weight. Soak it thoroughly with penetrating oil a couple of days ahead. If the engine is still runnable, You might run it and warm things up first to try and expand the cylinder head a little.

I would not suggest using a torch to heat it for fear of warping the head. Good Luck! Hard to Remove Injector I too am experiencing difficulty in removing the injectors on my The machine shop just notified me that they were unable to remove them. I hate to buy another head knowing someone will eventually rebuild this one. Are there any remanufactured ones available and where.

The engine oil cooler has been checked, the engine has never overheated so i dont think thet the head gasket is any problem. The engine has a gear case cover that houses the oil pump and pressure discharge valve.

The cover has no gasket and uses only a silicone gasket maker type seal. I can see there is point where the oil crosses between the discharge valve and the water pump housing area. I would like to know if anyone else has this problem, as I also have a t engine on another genset that has the same problem.

Do I use the silicone gasket maker again or make a gasket the old fashion way? Thanks for your help. Reply With Quote.

However, because the engine was 2. So we ended up paying lots of money to get the engine operational again. So yes, other people have had similar problems especially me. Re: Oil contaminated coolant I second the oil cooler problem. You say it was checked, but it can be difficult to make it leak in a test.

Hard to dulicate pressures, and temperatures that occur while running. And there have been issues with the original aluminum coolers. Bruce, I would be putting a call into deere to complain. Low hours and a known issue with cooler should translate into some kind of help on your failure.
