Transom clamp fixin’

[trex014]

So I have a couple of motors but namely my favorite Johnson rd-19 has a busted transom clamp thumb screw that I have finally gotten around to fixing. I’ve tapped out the old pin that holds the thumb clamp to the threaded screw but my question is,

what do you use to replace the pin that holds the two pieces together?

I know the original pin is aluminum and 3/16″ diameter but could I use the 3/16″ brass rod that I already have as a suitable replacement??

First time doing this so any pointers are appreciated.
Thanks

I’ve typically repaired them with aluminum rod, but can’t think of any reason why the brass rod wouldn’t work.

Well, if it happens to be salt water…….Dis-similar metals corrosion.

Excellent point – I obviously didn’t think about that one.

I have had some good luck with stainless roll pins. Their fit is a little bit more loose than I’d like but they don’t fall out and are easy to remove the next time.

Long live American manufacturing!
