I am doing at A/C delete because my A/C tensioner bolt broke and I planned on doing it anyway. So it was a convenient excuse. So I plan on leaving the alternator in the same place except it hangs down and I will use a turnbuckle for tension with the arm the alternator used to attach to. I came across 2 different part numbers (049903119L and 026903119B) for the pulley I need and not sure which is the right one. I did find the correct pulley on a car being worked on at Apex Tuning and that is where I gathered the information on what car the pulley would be on (92 Jetta / Passat 16V 2.0L).
So what I am asking is, is there a difference between the 2? If so which one is the correct one? Will my plan work? Is there a better (i.e. cheaper) way? Will those pulleys even fit on my alternator (85 Jetta TD w/AC (no P/S))? Is it better to get a different alternator with the correct pulley and add the tach connection?
Thank you in advance.
Check the FAQs.
You have the right alternator, belt and bracket,.. pully info is there.
I checked them. There was no A/C delete info.
I couldn't find it either.
Try "air conditioning" on vwdieselparts.com
My username might help the search over there.
I get the pullys for $20 at the local alternator rebuild shop.
That FAQ post needs a more searchable title including the words air conditioning.

1. Get that double pulley, install it with no shims and the belt will line up.
2. Do not grind so you can use the same belt unless you enjoy a lot more unnecessary work. Just get a longer belt.
3. Do not use an aluminum turnbuckle. Mine stripped the aluminum and became useless. Find a steel one with no play in the threads if you want to use a turnbuckle.
4. Lastly, a turnbuckle on top pulling on the alt is easier to work on than pushing from the bottom.
I made a belt tensioner with angle iron brackets and a long bolt after the aluminum turnbuckle failed and have no more alternator problem since.
Ever
Grinding the bracket allows a shorter belt and less flapping for the same tension,..
and I don't like the way it sticks out so far.
Less room for belt tensioning without hitting the radiator, a real problem when doing this on a MK1, not so much on the MK2.
