    05 pump washer?

    can someone do me a favour and measure up the washer that goes between the prop and pump on a Dynafly/05 pump setup please.

    i seem to have lost mine and need to either buy a new one at the local fastener place or make a new one up.

    thanks .

    I come up with OD 1.65" ID .875" thick .16" I measured with it install so there may be +/- some. This is on the DF and shaft you sent me as they are still married. We are installing it on the Dipstick conversion with a small hub pump.. Your old DF should be doing 80+ next weekend.

    isn`t the OEM washer between pump and prop stepped?
    number 32?

    OD= 1.6410
    ID= .8835
    Thickness= .1965

    Now there is the center step to it.

    Center thickness= .0780

    Hope that helps.

    Not meaning to hyjack this thread, But what is this that I have read involving installing the prop without the washer.
    Does this set the prop back? and what for.

    Leaving out the washer is like a setback yes. I dont recommend it.
    Have your local machine shop take 30 thousandths of your factory washer.

    anyone know what the purpose of the step is?

    is it critical to have it there?

    my guess would be: maybe>>> the step is the same diameter as bearing inner, and the larger top side of the washer larger to help protect the seal, to keep debris out, and the step is there to raise the washer a bit off the seal area, just a guess...

    FYI... If you remove the washer to mimic a set back it will make removing your prop significantly harder regardless of how much never seize you put on the threads...
