    JD 5500 series fuel systems

    Tech 7: I know it has been a while since you helped me with the fuel problem on a 5520 (back in January). Just wanted to mention that the problem is finally solved. I tried many things, but it was a combination of things that start with what I would consider a questionable fuel system...

    jd 5520 fuel problem

    Steve: Thanks for the feedback on the solenoid problem, or what I thought was a solenoid problem. Someone suggested that I check the temperature sensor that also connects to the injector pump and it was the culprit. Apparently had developed a short. When I disconnected the harness that went...

    JD 5500 series fuel systems

    Tech7: Where could I find out more about the DTAC on the fuel system? After I changed out the temperature sensor that is also attached to the injector pump, the tractor started and ran OK. I OHM'ed out the old sensor and it had shorted out which caused the injector pump solenoid fuse to...

    5200 fuel puzzle

    5520 blowing fuses to injector pump solenoid. As soon as the key would be turned on, the fuse would blow. I disconnected a plugin that goes to water intake just below the top radiator hose, and the problem vanished. Started right up and ran good. I think the water temperature has to do with...

    JD 5500 series fuel systems

    Tech 7: Almost glad to hear that I wasn't just being picky about my 5520. Sure appreciate the tips on how to purge the system. I made a trip to the JD dealer and asked about the primer not working and, as you said, it had little bits of rubber, bug parts, etc. Cleaned that and at least the...

    JD 5500 series fuel systems

    I own a JD 5520 that has worked well, but I am having doubts of reliability with fuel system. It is very difficult to purge the diesel lines of air even after a simple fuel filter change. I have other diesel engines, such as JD 2640, that is a lot easier to purge, even if it runs out of fuel...

    jd 5520 fuel problem

    Well, the mystery deepens. Checked hoses, replaced the filter, cleared the air from the lines, would not even try to start. Checked the fuel solenoid fuse and it was blown. Replaced the fuse and it will blow immediately. So, I guess that the fuel solenoid is bad? What does a person do to...

    jd 5520 fuel problem

    F-I-T: Thanks for the response and leads on what to check. Will do that first thing in the morning. Couple of questions - can I just reroute the return line to the tank into a container? Does the engine depend on gravity flow of diesel? Seems like the problem gets worse when the tank is...

    jd 5520 fuel problem

    I have a JD 5520 tractor that has an apparent fuel problem that seems to recur. It will run normally most of the time, and suddenly start "sputtering" and losing power. Revving the engine will clear the problem and return to normal. It happens pretty frequently - like every 15 minutes or so...

    Burned up Kubota engine repair

    Many, many thanks for the helpful information. Going to pursue some of the leads and will post back what happens. Just doesn't seem right to have a nice, clean tractor with no engine to power it. I sure hope this isn't something that becomes commonplace some day - our throw away society...

    Burned up Kubota engine repair

    I appreciate the replies and suggestions. I too find it hard to believe that a reasonable aged tractor (1993) would be ready for the junkyard because there is not an engine that would fit as a replacment! He is willing to buy a new engine if he can find one. Toyota says that they are simply...

    Burned up Kubota engine repair

    I am a new user and am trying to help a neighbor with a problem that he needs help with. He owns a 1993 Kubota M4030 SU tractor that he purchased new, which he has cared for carefully, kept in storage when not in use and the tractor is still like new. Unfortunately, and this is bad, the engine...
