• I have been looking through the forums but I can't find it. I know there is a mod you can do to the alternater with  a tdi clutched pulley. Does anyone know the vw part number for this part? My car is a 1.9 AAZ engine with a/c and p/s. Thanks!

• I did this mod. It worked amazing. I don't remember the part# but I can see if I can find it anywhere or read what it says on the pulley. It was expensive. It cost over $200 with tax at the stealer. I'm actually working on doing another now and need the # again too.

• sweet! Thanks !!
  
  Has anyone tried those 2 different pulleys that were mentioned in that post to see if the cheaper one would work? Also, is there any place that would sell that spline tool??

• Are the shafts for the alternators the same size for the 70 amp 90 amp and 120 amp? I think I have the 90 amp since I have a/c.

• Cheaper one *won't* work (wrong offset), pretty sure the shaft sizes are the same, and please put your location in your profile so someone can refer you to a vendor that makes sense for your spot in the world!

• sorry about the location thing, that has been fixed.
  
  so part number 022 903 119C will not work and part # 028 903 119 AA will work , correct?
  
  I believe altrom carries that part so I will give them a call and see how much they charge for that part. Is there a special bolt or locking washer that is used to hold the pulley on?? Should I be putting locktite on the bolt so it dosen't come off? What size of bolt was used? I have another 90 amp alternator that is out of the car so I can install it on that one and then put it into the car.
  
  I can't believe vw sold the car with out this pulley on it. I recently changed my tensioner for the serpintine belt because the old one seized up putting too much pressure on the belt causing it to break. I guess with that extra pressure it prevented the belt from bouncing and the noise. I put this new tensioner in and I thought that there was something wrong with it only to find out that this belt bounce and noise is normal with a properly working tensioner. If this clutched pully fixes the problem I will be buying another one for my other 94 aaz 1.9 jetta.

• thanks for the link vincent! Are they a reputable company to buy from??
  
  Also, the bolt that you used to hold the clutch pulley on, what size was it? Did you use a locking washer with it? Was locktite needed?

• This thread should answer your questions regarding alternator clutch pullies on 1.9 TDs:  http://forums.vwvortex.com/zerothread?id=4323099.
  
  And yes, Roseland Technical is very reputable.  I have dealt with him on a few occasions and have always been satisfied...fast shipping, correct orders, decent price etc.  He sells stuff from Altrom as well including the clutch pulley.
  
  As for the last question the spline tool is 3/4 of the way down the list...MN3400SET.

  The bolt's actually quite optional... I did it since the early pulleys had a slight habit of seizing, which might make it spin off the shaft.  
  
  The later versions don't seem to have this problem, and as delivered from the factory standard VW alternators have no additional locking mechanism on the pulley... it just spins onto the shaft and tightens down.

  His catalog is "representative" of what he can source... he'll know exactly what you're after when you contact him directly.
  
  If you google for Metalnerd you'll find their on-line catalog, including their spline tools.
