Hello all,
I managed to loose the pin that keys the impeller to the drive shaft. It looks like a 1/8” pin, approx .300” long is what is needed. I haven’t found a local source that sells solid pins and hate the idea of paying $7 plus shipping for a correct one if a simple roll pin will work (which I already have a selection of). Any words of wisdom on replacing the pin ? Unfortunately, I don’t have a metal lathe to make one.

January 16, 2023 at 4:52 pm #271258I would not advise using a roll pin.
January 16, 2023 at 6:00 pm #271267How about a piece of a nail? Maybe a welding rod stub? The flux will sand off an electric welder rod easily! How about a coat hanger? There are some that are close to 1/8″ Those prices are nuts!

January 17, 2023 at 12:28 am #271305I thought it was a very bad idea to use anything but the correct shear pin as the use of a material that has a much higher shear strength will defeat the purpose of the shear pin and allow the forces from a prop strike to damage engine internals.
When I was young and dumb I used sections I’d cut off from a brass rod my buddy gave me. they worked a bit, but were too soft and didn’t last long. Finding out exactly what the metalurgy is on those shear pins and getting a length of rod would be the way to go.

January 18, 2023 at 1:36 pm #271380Thanks for the feedback. I was thinking that a softer steel might corrode too much. I recall that hardened steels tend to rust less and I think the original was a hardened pin.
