Car keeps eating ac/waterpump belts. Please help.

VW had a lot of trouble getting me the right part, it wasnt a part listed as for the car, but I am pretty sure it came out of the factory with it.  So I wouldn't trusk EKTA here.

Are the 2 pulleys on crank the same size and the 2 pulleys on the waterpump the same size?  On my car, it appears to have larger inner pulley on the crank to spin the waterpump faster.  The 2 pulleys on waterpump are same size but the outer one freewheels to allow the different belt speeds.

My crank pulley is the same diameter for both "Tracks", the outer track runs the power steering and the inner track does the rest. My WP pulley is only a single track. I'll have to take pics of my setup. Seems like there's too many damn variations that VW used.

Thanks for the info. 10mmx 30mm Hex head right? Anyone have any idea what the pitch would be?

For your belt problem, I have never had a problem with WP/AC belt on that set up. My problem has always been ALT belt related. I was able to add a spacer behind ALT pulley to align the pulley with idler tensioner pulley and that held for 25,000 miles+ (better than <2500 previously). Also have heard a lot about the bearing for idler pulley (6202-RS). You sure that something with your ALT belt setup is not putting unnecessary tension on AC which is causing WP/AC belt to wear prematurely? Just a thought.

Forgot to mention, also make sure those Hex bolts that allow the AC to pivot are nice and tight... They are a pain to get to and sometimes never get tightened properly, which causes the AC move/vibrate and eventually loosenes the WP/AC belt.

Well I changed the belt yet again. Made all the bolts extra tight. Much tighter than I ever have, and marked the position of the compressor with a sharpie. We'll see what happens, but fortunately it's getting cooler out around here so hopefully I wont need to use the a/c much. Wish me luck.

main reason I got my a/c working again was for the defog  

I had to pull my car over one cold morning coming back from work because of sun glare  :x

Anarchy-

Just wondering if you had part # for bolt #39 and nut #40 on that diagram. Any dimensions for these parts? 10mm?

Thanks
