Easy fix for Squeaky / Squealing Belt

[andrewmcg]

Ok, using the picture below, you start by tightening down bolt #1 all the way so it wont budge. Bolt #2 is in stock location and needs to be loose. Bolt #2 is the one that moves with the alternator and moves as belt tightens or loosens. Now L brackets should be about 1" apart and you put bolt #3 in and start tightening. As you tighten #3, it pulls the alternator out towards the front of the car, also tightening the belt. Once you like how tight the belt is, tighten up bolt #2 and it will all stay there. Viola!

Ah thankyou. The brackets being together is what threw me off. I always need everything explained to me.

Speaking of that, what size is that angle iron? 3/4 inch?

Oh and I have an improvement! (subject to approval)

Welding the nut that the adjustment screw goes into to the angle iron will make adjustment easier.

And am I right you also need to drill holes in each piece of angle irion for the bolts going to the adjusting bracket?

Beautiful, simple, effective, cheap design!
