    LOcked and broken head and rotor, shop tells me a stuck injector can do this, Pump looks recently rebuilt, we have owned the machine 5 years, ringed it and 1 liner kit 800 hrs ago, Ran fine all this time, stopped with the bucket in the ditch.LOL
    Sheared the shaft.

    Injectors can DEF. do it.. PLEASE get them checked before u bolt on another pump.!!
    They didnt press it apart.?? We have a "seizure chart" that will lead u to the cause..by "where" it seized.
    I'll look to see what I have..

    I have been a diesel mechanic for 40 + years and never heard of the injectors causing this till they told me. Makes sense. In all those years I have never torn down a DB2 , and I have an IDI ford website. LOL
    I just know my limitations, Ive used the same shop in that 40 years.
    And I NEVER do fuel pump work without getting the injectors tested or doing it myself.
    Let me know ,thanks

    I checked all my stock & nothing will work..
    The DB2-4359 wont work either.. H&R & Dr.Shaft are different.
