Where the heck is that thread about cool tools that people made or use?
It's from years ago from what I remember. A V-8'er had grafted a wrench to a prying point to help lift that stubborn genny with a lever applied to it. JM35's super engineered steering and rear hub pullers were in there too!
I love your idea because adjusting that belt without getting a little medieval is a challenge.
Just recall your deflection at midpoint. That belt don't have to be TIGHT to spin the pumps and power maker. But too tight will jack their shafts up eventually.
