Big screwdriver?

Seriously, I normally just use a screwdriver or small pry bar wrapped in a rag. Generally, you only have to tighten the one adjustment bolt to get it to hold fast. Then you can let go and tighten the pivot bolt.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Okay, I'll be interested to hear if such a thing exists. Haven't heard of a tool like that, but then I've never needed it.

Maybe Maine Sail has a suggestion?

Now that I'm pondering this a bit, maybe the answer isn't a tool but a different bracket. I have a fuzzy memory of having seen somewhere a "ratcheting" adjustment bracket. Instead of being a smooth arc where the adjustment bolt grabbed only by compression, it was finely notched or geared, and the bolt had cogs that would walk up the bracket to increase tension.

I'm trying to make a belt tensioning tool out of a turnbuckle. Prelim test shows it'll work. Just put the turnbuckle between the crankshaft pulley and the alternator and turn to expand the turnbuckle, it'll push the two pulleys apart. The trick is fabricating both ends of the turnbuckle so that it won't slip off either pulleys. Good luck.

This is what you want. Took a course at Mack Boring on Yanmars and this was recommended. It works great!

The belt tensioner suggested above is great but only for certain engines. My 4JH Yanmar requires something around 17 inches spacing and this item only extends to 15 inches necessitating use of another spacer making the whole concept too impractical compared with the screwdriver/pry bar technique.
