    If I ever knew the definition of Lynch pins I had forgotten it
    I did look up the definition of Lynch pins and Cotter pins and you are correct.
    Thanks, I learn something every day.

    The last step was mounting the plow back on the truck.
    The large cotter pin on the right attaches the lower plow frame to the truck frame bracket. The cotter pin to the left goes in the stub shaft, which is the one that we repaired. This cotter pin keeps truck frame bracket link from falling off the stub shaft on the upper plow bracket.

    I built up the ends of both of the stub shafts with weld.

    Then I drilled a new hole for the cotter pin.
    The following picture shows the cotter pin in place in the new hole of the newly built up shaft.

    Western Snow Plow Stub Shaft Repair

    My customer just purchased a used Western snow plow. The pump worked fine, the blade had a lot of life left and the hoses were new last year. The only problem was that the stub shafts that attach the upper plow bracket to the truck frame bracket were cut off for some reason.
    The location for stub shaft that needed to be repaired can be seen in the following exploded view.

    The 1st stub shaft was so short that it even lost the cross hole for the cotter pin, so there was no way to keep the truck frame bracket link from falling off the stub shaft of the upper plow bracket.

    To get the plow to my house, my customer had to ratchet strap around the truck frame bracket link to hold it onto the stub shaft. As you can see in the following picture the stub shaft is just barely flush with the truck frame bracket link.

    in the second picture truck frame bracket link was removed so that you can see the end of the first stub shaft, which was so short that there was no longer a hole for the cotter pin.

    On the 2nd stub shaft there was only a little bit of shaft beyond the hole to support the cotter pin. My customer wanted this shaft also built up because he was worried that the cotter pin might pull out through this thin wall on the end of the stub shaft. This picture shows the truck frame bracket link on the 2nd stub shaft.
