    Default Help identifying oil pump S&S - shovelhead

    Hello!
    I'm in the process of helping my friend with his bike (Shovelhead 73)
    His oilpump is shot and i've found a replacement - i think. All manuals/instructions i can find on S&S oil pumps are the billet ones, which this doesn't seem to catagorize under.

    Will this one fit without modification or do i have to do some work to the case?

    You must drill one hole in the motor case for the pressure relief valve vent in the pump.
    As near as I can tell from your pictures, that is the only change you will have to make to use that pump. That hole is drilled with a jig that S&S sells. It is the same vent hole that the '81 and up HD pumps use, and is a common change when using a newer pump.

    Do download the S&S oil pump instructions as they provide pictures and details of the pump installation.

    There should be part numbers on your pump, which can help determine what applications the pump was made for. There are several different versions.
