I had the same problem on an 82 Chev 6.2 diesel. It would destroy the alt belt within 4~6K miles so I had to replace it every time I changed the oil.
I replaced the alt. and all the pulley's and everything lined up perfectly but it still did it and I never did figure out a fix.
The only thing I could think of is that since it didn't have AC, the belt had a long, straight shot between the pulleys. In this space the belt would whip inward and outward in a blur of motion continuously. Did it no matter how I tightened it. I think this fatigued the belt to failure. I thought about trying to create an idler to control the motion but never got around to it.
Sorry that's not much luck but maybe it will give you some idea's.
Hope you have better luck.
