    Bill the clutch is not driven by the impeller pin the 2 holes are outside the pump.. one for the clutch and one for prop without clutch as I have said ..

    This is a KD3S. If I am not mistaken, the KD4 is the same?

    Long live American manufacturing!

    Parts Illustration above shows only 1 pin. Which is correct for those
    models that have the rubber biscuit clutch.

    Certain models did not have the clutch. They used a shar pin in the
    rear hole in the prop shaft and a short pin in the impeller drive hub
    that was held in by a circular spring in the groove around the
    impeller drive hub or eccentric cam.

    Note that the clutch can be left out and a sheer pin used
    on all models IF a short pin and spring are used to drive hub or cam
    That requires the spring to retain the pin.

    Simple ingenious either or design provided all the right parts are
    in place. It is worth noting that prop shaft is same for all modes
    from `940 K1 thrue WG4…regardless of brand, single or twin, clutch
    or shear pin or whichever water pump.

    Note: the 1940 16 square hole water pump had a more complex way
    to drive and retain the water pump oscillator cam. Used same prop shaft. 1941 7 slit design was modified as above. Propeller was
    changed to allow for either clutch or shear pin drive..

    Good information. Thanks
    What’s the call on the flywheel? I’m not painting the flywheel but what about the, well not sure what it’s called. The pull rope goes around it. Paint it dull aluminum? I’ll post a pic.

    Loo-ken good! Now the fun part starts. When the nice clean parts go together maybe some new parts you can see some progress being made. Don’t forget to make the screw heads look good.
    Love it!

    Screws are already polished. Just trying to decide on a paint. I have some dull aluminum from NY marine. Doesn’t match the original. My plan is to leave the prop in original condition which is pretty good. Maybe I should try to match that paint? Any input is appreciated.

    I would like to remove the screw portion of this clamp to blast and paint. How can it be removed and replaced?
