Interesting. Is that just wedged in place? This is timely as I need to change my belt

My version that can be kept in place. Two rod ends with a "turnbuckle-style" connecting rod (fits 1/2" wrench). One end left-hand thread, the other right-hand thread. Nuts added on both ends to lock against the connecting rod and prevent spontaneous turning.

I did similar in a previous boat. Replaced the alternator arm with a cheap hardware store turnbuckle. It worked so well I had to be careful not to get the belt too tight. The cheap turnbuckles don't have lock nuts so I had to add them, hardware store didn't have left handed nuts but I found one at West Marine.
