    574 injection pump throttle shaft starting position

    Both pins rotate although the top one is pretty stiff. I got the tractor back running by adjusting both shafts amd rods based on photos i had taken. I had not initially mobed the lower shaft and the upper shaft was a new replacement with a new pin. I think i will adjust the throttle shaft one...

    574 injection pump throttle shaft starting position

    So my 574 had a broken throttle pin in the injection pump. The tractor was idling at about 1500 rpms but no theottle response. When i put the new piece in with the new pin on it i aligned the pin to the slot in the end of the shaft. The slot in the shaft was sitting at about 11 o'clock. I...

    Bosch VA CR injector pump throttle pin size

    Got my 574 running butbit idles around 1200 RPMs. The throttle rod moves on the pump but there is no throttle response. From what I have read this is likely a broken pin on the throttle mechanism in the injector pump and can be repaired without removing the pump. I have read that the dowel pin...

    574 no diesel from fuel tank

    I got the tractor running now. Runs real good. It idles too high and has no throttle control. I suspect that pin is broken off but i suspect that was done before i got it. This pin can be repaired without taking the pump off. It is a 2mm x 12mm pin and can be replaced pretty easily from the...

    574 no diesel from fuel tank

    Thank you for the reply. It took me a bit to figure that out. The challenge is that the fuel lines kind of disappear and comw out on the other side. No i have fuel to the filters and to the pump. I need to try to bleed the air out of the pump as it has been sitting for 6 years. Somw debate...

    574 no diesel from fuel tank

    I figured out my problem. The fitting at the bottom of the tank i was plowing air in was the return valve. That must be a one way valve. And the hose i was blowing in at the filter was not the same line i was testing at the tank. This tractoe is new to me. I will figure it out.

    574 no diesel from fuel tank

    I have a 1976 574 tractor that is not getting any diesel fuel to the filters. I ran some air backwards through the feed line at the top of the filters. It was hard to tell if it was plugged or not so i took the line off the output on the bottom of the tank and no flow. I then ran air backward...

    140 Hydraulics quit working after sitting for 15 mins

    Thanks Jim. I appreciate the follow-up. I will make sure he has the tractor running. LOL. What would you say is the most likely culprit for an air leak? I know that they used this same system on various models.
