    Local contractor blew up his 3306 #92e1174 b914x

    Those are the serials he provided me. I have a running pull out from a cat grader that has a serial #72g640 on the engine tag.
    They want the block and crank. I'm tryin to figure out if they would be the same.

    Any idea where I would find the engine serial on the grader block?
    The casting on the block is a 2p9600
    Any help would be much appreciated.

    I am not sure what the S/N was when the 92E moved from the D333C to the 3306. I have seen two 92E D7F's with either engine.

    If the block has the dozer S/N stamped on it, it is a D333C. I think the 3306 they used was a 44V.

    A 72G is a 14E grader. I am suspecting that is a D333C as well.

    From what info I have been able to gather the 72G640 is a D333C and didn't become a 3N 3306 until s/n 72G1341.
    The 92E1174 is also a D333C and from what I see for a parts book run the same manual covers 92E1 to 92E1751 and then would change to the 3306. I didn't get a chance to check the 44V designation for the 3306 but that's probably correct for a Japanese build.
