  1. IH 684 D239 injector rings?

    Thanks for the feedback - I'm going to replace the sleeves - I thought that it wouldn't such a big problem to take the injectors out and back in again. about the water in oil problem - when I took out the oil sump out i saw that the water was coming out from the engine block lateral oil holes. From this I figured that it had to be from 1) a severe engine block crack as the water flow was high 2) head gasket or 3) cracked head i took the head to a shop which pressure tested, refaced and did the valves. The test result was ok, they found holed expansion seals and corrected the seals. I replaced the head gasket - seemed too be too glued to the engine block to be in a healthy state. Reassembled the whole thing and no more water in oil. As such, I don't believe the water in oil was due to the cylinder sleeves.
  2. IH 684 D239 injector rings?

    Well, installed the injector nozzles and used the tractor for a while. Sounds and worked good. But when I stopped It I noticed that two of the injector nozzles were wet with diesel near the dust seal rings. The injector nozzles clamps were torqued according to manual. as such I have two questions: 1) could these small leaks mean that the sleeves and injector nozzles should be replaced? 2) I read somewhere that the injectors should be installed in such a way as to have the return line screws face the rocker cover - when I bought the tractor these were facing the left out side of the tractor - as such I reinstalled the injectors in this same way - can any of you confirm how the injectors should be installed? thanks in advance.

    Thanks a lot - I'm going to install the injector nozzles and check how it goes.

    Is it supposed for any rings to be put at the bottom end of the injector nozzles inside the liners?
  5. IH 684 D239 injector rings?

    Hi, After having noticed the IH 684 was heating up and having water in oil, I removed the engine head and replaced the head gasket - the problem was really not the gasket but one of the head's expansion seals. Anyway, I'm in the process of putting the injector nozzles back in the head. To do all this i bought an engine head gasket set which includes a set of rings. As the nozzles were not removed by me (it was done in a shop which tested and faced the engine head) I'm uncertain which of the engine head gasket kit rings should be used in the injector nozzles... I have attached an image of the injector nozzles and another with the rings included in the gasket set. Would you guys be able to indicate where each of these rings should be used? And if any should be used in the injector nozzles? Thanks a lot for your help, Antonio Lourinho
  6. IH 684 - oil in water

    Hi, Thanks for the photos. So you put a water hose into the engine coolant inlet and watched it go out by the engine outlet as if the water was coming back to the radiator - is this right? Thanks you,
  7. IH 684 - oil in water

    Thanks a lot for the response. Although I know I should have avoided it I couldn't resist starting the tractor today again - it worked ok and no overheating nor black stuff coming out of the radiator. I will not try it again before doing a radiator flush until is becomes clean. Regarding the radiator flush, do you have an idea of how it should be done in this model? Is there a valve in the engine to let the water out while I put the hose in the radiator filler hole? Should I start the engine to warm it before starting? Thanks in advance.
  8. IH 684 - oil in water

    Hi, Before I started working I put some tap water in the radiator. I thought it would be enough - apparently not. Should I use tap water at all? The radiator started to overheat and push water out. The black stuff I assumed it was oil but I'm not sure. Ive never put antifreeze in the radiator...since I bought it - this is the first time I've ever put the tractor to work since I bought it besides putting it at idle. thanks in advance,
  9. IH 684 - oil in water

    Hi, lookinh at the oil cooler again it is connected only to two hoses, which I believe are the oil inlet and outlet. Water does not seem to get in the oil cooler. If so, oil cannot be getting in the water in the oil cooler. Am I thinking this right?
  10. IH 684 - oil in water

    The oil engine level seems ok - nevertheless the oil coming out from the radiator filler was not much - it might not to be noticeable in the oil level due to that... I took a look at the oil cooler - in the outside it doesn't have oil in it but I suppose that the problem can be on the inside. Should it be pressure tested under heat to check whether this is the problem? thanks in advance,
  11. IH 684 - oil in water

    Hi, Today i have been using the ih 684. After about an acre it started blowing vapor from the radiator cap. After stopping it I noticed a black liquid that was coming out of the radiator overflow tube - I've had water fully refilled before starting the day and as soon as I stopped the tractor it was completely empty. What can be causing this? What things should I be checking? Thanks in advance.
  12. Ih 684 hydraulic related noise and vibration

    Hi, That was it - putting the lever in the center position solved the problem. thanks a lot.
  13. Ih 684 hydraulic related noise and vibration

    Hi, where is the remote hydraulic control valve located? thanks in advance.
  14. Hi, today i started the ih 684 and noticed a strange noise underneath - I noticed that the noise does not occur when I steer the wheel (which is hydraulically assisted) or if I move the rear hydraulic arms. The noise comes back immediately after. I tried to find the origin of the noise and found a leak - by smell it seems to be hydraulic oil. The pipe is quite thick located under the fuel tank. This pipe vibrates a lot. is there any way of fixing this kind of pipe? Is it normal for this kind of pipe to be vibrating due to a leak? additionally, in this tractor there is an oil cap in the rear and a stick near the left foot step. Using the stick I can see that the oil level is ok - are these stick and cap for the hydraulic oil - can oil be put into the rear cap if needed? thank you.
  15. IH 523 D179 Neusse normal oil pressure?

    Hi, i do not know about the oil pressure but I always use 15w40 on my ih 684 as I believe is the best replacement for the sae 30. Could you elaborate on why you used 15w30?
