After a month and half adventure of changing my clutch and transmission repair, I get her ready to drive and my belts slipping. 3 belts from Autozone later and still can't get it stick. I've searched every corner of this forum for an answer and I can't seem to find a fix.
Here's a list of everything replaced/repaired on the car since it ran last: New Clutch/pressure plate from autozone New throwout bearing fork bushings and seal New slave cylinder New Alternator (broke the bolt off in it trying to put a new belt on) 3 15505 belts from autzone (now know they're cheap crap) New Napa 7500 belt (currently on the car) Water pump seal
The car's an 84 SE with an 85 L4 and 5 speed in it. AC is not hooked up. I got it to run for 10 minutes today with the new belt and cleaned pulleys before it started to slip again. Pulleys appear lined up, I assume I'd know if they were out of line enough to cause problems. Everything spins fine. Any Ideas on what to check next would be much appreciated.
Maybe try a shorter belt -- run for short break in period and then gently retighten. It's not unusual for a cheap belt to stretch haven't heard of a new stock NAPA belt having a problem. Also how is the belt riding in the pulley? When it's tightened, is the top of the belt flush with the top of the pulley or is the top of the belt below the top (riding inside) of the pulley?

The Napa belt rides flush with all of the pulleys. The one I got from AutoZone sat down inside a little bit. I'll try the break in procedure after work tonight. I've heard good things about the Gate's and good year belts, and will try that next.
Also be sure the grooves in the pulleys are clean. They can pack with oil and dirt over time and fill in some and still look like it's metal. Are they all in the same plane. Alt pulley not spaced in or out to the water and crank.

over or under tight belt can fail. Over tight will break the cording then belt will slip, even throw off the belt.
Clean pulley w/ brake cleaner. Not carb cleaner etc that many leaves a bit of oil behind. Binding alt or wp can kill a belt. worn out crank pulley can kill the belt.

give dodgerunner a pm. he makes a bracket to install a 3100 spring loaded tensinor on your motor. it makes the belt have more contact surface with the alternator and shuts the pig squeeling up for good.
Update: Think I finally got it. It was a combination of dirty pulleys, cheap belt from AutoZone, and I added a washer on the wrong side of the alt. Adjustment belt. She runs like a champ now. Thanks guys!
And...it's back. After a couple days of of no squeal it started on my way home today. However this time it's only at an idle. Anything over 1500 rpm it's gone. I was reading another thread that mentioned the width of the wp gasket could be enough to throw the pulleys out of line. Is that probable? To the human eye the look lined up, I haven't used a laser our anything to verify.
