researching ideas for brackets and alternator for non AC

[92EcoDiesel Jetta]

I am toying with the idea of getting rid of the AC system in my 92 Eco since it makes changing the alt belt such a pita. lmk what you have and how much shipped to 11357.

Same bracket. same alternator.
 get rid of AC and rotate alternator down.
 Figure out how to adjust it. Custom adjuster bar or custom bracket on alternator to work with a normal adjuster bar.

 Special double pully lets you use a wider belt.
I posted the whole swap over on vwdieselparts.

Please post a link of your swap.

I wish i had found this months ago.....

Fatmobile, where is it that you found this "special double pulley?"
Are these readily available somewhere....or what? Farm store....parts store.....magic fairies?

I went to an alt shop and they bust one out and installed and sold me it for a few bucks.

 I listed the part # and parts catalog it came from in the post tyler linked to.
 The pully I used for my swap came from the WAI catalog.
Part # 24-2106, for the 1/2" belt
or 24-2105 for the 10mm belt.
 I went to a local alternator/starter shop for mine, heard it's from a ford truck.

What do you think is less work?

1. Modify the brackets of an AC setup as you have done.

or

2. Buy brackets from a non AC setup and do a swap?


You gave p/n for 10 mm and 1/2 double pulleys. Which one did you use and which do you recommend and did you have to change the crankshaft pulley also?

Buying brackets is the easy way to go - but not the cheapest. I got mine from a 1978 rabbit without AC, guy shipped the brackets and alternator to me for $120 total. I bought a 1985 golf that had the non AC setup soon after that and did the swap to my other car. I see these on vortex every now and then.

Since we are dealing with a MK2, the main cast bracket is the same, AC or not.
 non-AC setups are 65 amps, I prefer the 90 amp AC alternators.
I used the 1/2", did you rear the post tyler linked to?

Thanks for the info! I have never seen a non AC MK2 setup and was under the impression that non AC MK2's had a different bracket and had the alternator mounted down low as in a MK1 non AC setup such as my 81 Caddy.

I also didn't know that MK2 with AC has a 90 A alternator. I agree a 90A
is more desirable.

I did read your post Tyler linked to but I guess not well enough.

yeah the non ac goes down low and the ac one goes up top and i think thats where lots of cars have a problem with the mounts and wallowing out mounting holes.  every car i have come across in the junkyard like that had nasty looking cocked and jerry rigged alternator mounts.

i need to research myself if you can put the guts from an ac alternator into the casing of a non ac alternator?

i have my own issues with mk2 mount in mk1 right now with a mk2 radiator.  might not have been a good idea for me to put big radiator in but its what i could get at the time.  non ac alt is in right now but i think the ac casings have holes flipped around.

[92EcoDiesel Jetta]

fatmobile, did you do the grinding of the AC bracket installed in the engine or removed? I really like what you did going to 1/2 belt with the double pulley. Did that eliminate belt stretch, squealing, and frequent belt tension adjustment? What length belt is needed and does the belt flop or is it steady?

That double alt pulley might also be the same as on a Mercedes Turbodiesel 81-85.  I have essentially the same Bosch alt on mine and I have swapped pulleys around on some of them.
