1.6 TD A/C alternator help???

[funkaholik]

So... the alternator in my jetta appears to be the wrong one.  The pulley doesn't line up perfectly with the A/C pump and it's ruined the alt bearings.  Sounded like a nest full of birds under the hood and just chewed the belt off.

Does anyone know the part # for the correct alternator for a 1.6 TD with A/C?  Engine code is CY.

Does anyone have a correct upper alternator bracket they can part with?  It should have the toothed rack adjusting mechanism.  The PO ground the teeth down on mine and bolted the alt from the back. (?!)

There is no Bosch sticker with part # on this alt, like there is on the alt in my caddy.

Any help, parts, or advice greatly appreciated - can't drive my baby till she's got amps...

If you have AC, and a MK1 alternator setup, it should take a Bosch AL22X. Many places carry them and they usually include a new pulley. That's an nice feature.

I should note however, if the alternator is correct for a MK1, then someone probably screwed with the setup to make something work, where it should not go.

For starters, your alt bracket should NOT have teeth on it. That's the first bad sign. Also, if the pulley was not shimmed properly, that would cause you to eat through belts (as will rust-pitted pulleys).

Good luck.

Sorry, I should have specified that this is a MK2 Jetta, 1992.

Ok then. You need an AL30X if you have AC (or at least, still have the compressor).

If no AC, then it's an AL172X

You should be able to find either at your local cheapie auto parts stores (or their proprietary equivalent). I will say, if you happen to go that route, be sure to get the lifetime warranty. Those places use ***e parts when they rebuild them. You'll be lucky to get 2 years out of the diodes and regulator.

I'm not sure if the Bosch AL30X comes with the pulley. I bought one not too long ago, and it did not include the pulley. They may include them now.

I had a real run around the first time I bought a new alt ( <hangs head, kicks at ground> I was in a hurry!) at C-Tire,  as it wouldn't line up. Like a bit more than a quarter inch. Pretty visible just from looking. Checked all their other ones in stock too. This was after I tried the alt off my A/C equipped parts car, as well. Even ran it, tensioned with a cargo strap, for a short while. I couldn't afford the downtime.

Short version. I had to play swapsies and ended up with a machined steel pulley that may or may not be the 'correct' one, but it lines up, that came of a wrecker yard Bosch alt. I've built a couple franken-alts since, swapping wrecking yard alt parts onto proper housings and reassembling them, and this pulley and washer combo has migrated across, and the 'new' pulley gets fired under the bench or put onto the donor alt for use as core charge filler.

 Good luck! I suspect some rebuilders catalog somewhere printed the wrong offsets and they've been running with that since. Minor PITA.
