    IH 666 Injection Pump Problem

    You're right, I would not know what to look for in the gear pump unless the function is simple and obvious. The atory again from the beginning is that the tractor would not start after sitting several months in winter. I tried the primer and it did not work. II changed filters and put in...

    IH 666 Injection Pump Problem

    Dieseltech, thank you for your efforts to help me. The primer does not work and cranking the engine also does not deliver any fuel to the transfer pump outlet, even though there is a good flow of fuel to the inlet. I am tempted to remove the transfer pump from the reat of the injection pump to...

    IH 666 Injection Pump Problem

    Neglected to say I used higher pressure when pressurizing the inlet line. Will try it again tomorrow with no throttle. The hand primer will suck up fuel but completely resists down pressure.

    IH 666 Injection Pump Problem

    Well, with throttle 1/3 and outlet line removed, I pressurized the tank. Low pressure with shop vac outlet. Nothing. So I pressurized the inlet line at the filter end. Still nothing, not even a drop at the outlet.

    IH 666 Injection Pump Problem

    On the IH 666 pump, I removed the 7/8 cap and spring. Couple strokes of the hand primer, I could hear something come free. I also gently pushed a drift into the transfer pump inlet and could feel the nylon valve move. The hand primer will now suck up fuel but still not push it through the...

    IH 666 Injection Pump Problem

    Hello Dieseltech, glad to see you posting. When you have time you might go back to the thread about my Case 1030 Bosch pump. It is now off the tractor and on my bench and I'm wondering about any possible soak procedures to save rebuild cost. Thanks.

    IH 666 Injection Pump Problem

    Yes both the 666 and the Case 1030 sat unused for a few months last winter. The 1030 has a history of B-20 fuel but not the 666. It was a running tractor. I swapped the primer pump in the 666 with a working pump. By the "charge pump" I am referring to the transfer pump at the rear of the...

    IH 666 Injection Pump Problem

    My IH 666 has the American Bosch injection pump, I have a good flow of fuel to the charge pump from the primary filter, but fuel will not pass the charge pump either with the hand primer or cranking the engine. Thoughts please. John

    How to bleed injection pump on 1030??

    Probably why he has not responded further through TractorHouse. Best to wait until he is ready to sign back on.

    How to bleed injection pump on 1030??

    Thanks for your advice. I would like to contact Dieseltech directly although I'm on a Mac. I'm not going to disassemble the pump. I've gotten some advice that it may be possible to soak or spray that moving parks, and that is where I am. I've got three injection pumps with problems right...

    How to bleed injection pump on 1030??

    Coming back to you Dieseltech. The 1030 pump is now on my bench, exterior cleaned, side cover and transfer pump removed. Is thre anything I can do, a soak or something, to free it up before sending it for service. This is the one that sat after use of B-20 fuel.

    How to bleed injection pump on 1030??

    So the 1030 pump is now on my bench, cleaned exterior and removed side cover and tranfer pump. No obvious sign of bio-diesel but the rack still moves only about 1 mm. So my question is how to proceed from here. Is there some soak I can try to fee it up.

    How to bleed injection pump on 1030??

    Removed the pump on my 1030 today. Haave not opened it up yet. Definitely had B-20 biodiesel goo in the fuel lines. Tank will need to be removed and flushed, probably fuel lines replaced. I'm thinking about an auxiliary samller tank to provide gravity flow for moving the tractor short trips...
