On my 'ol K20 I've had never ending problems with the alternator bracket because it angles the alternator back and puts a lot of stress on the belt. It also makes the belt go through periods of wanting to scream and not which will drive you crazy. Here is a picture to show you.
The green arrow points to where you can adjust the bracket in or out, but if you continue on down my second picture will who you that it needs to go out quite a bit more
And this picture show's you how far the belt is actually tweaked! [img]images/graemlins/blush.gif[/img]
Any idea on what to do, I realize I ultimately have the wrong bracket, but this <nobr>truck</nobr> was kinda pieced back together a few years ago after sitting for 12 years so I'm still working bugs out. Should I just cut off the where the adjustment stops the braket and weld some pieces of metal on to extend it I really don't know where I would be able to find another bracket around here because junk yards are not in abundance in my area. So any ideas on what I could do to make this one work would be great.
Problem with making that bracket work by piecing it together is that it will still slip. There is supposed to be a lot of tension on that belt. All the tension will tweak the bracket and then you are in the same place you atarted. Try the dealer or junkyard for a proper bracket.
