| Just as info; The Bosch alternators are really easy to service and the parts aren't expensive. Can be done yourself but a car electric workshop will do it in no time and can/should bench test before delivery. |

I destroyed the old 120A trying to get the rotor out. Now I know how they're done.
I was wondering if I can press out the rotor coils and weight masses out of the shaft itself: answer:NO 
Do you have any addresses that would sell just the 140A rotor?
If not,I will have to buy another 140A alternator,damn it!!

But of course!

That would be USD 180.
You can get all the VW free wheels as well, or any other brand if you find one that fits.

Still, I would choose a bolt on 120 A.  |

Thanks for the link Svenakela
Dang, I'll try to find a used alternator to steal the rotor from, or try to re-sell mine (2012) and buy another alternator.
The amperage is not the issue here, it's the fact that I bought an alternator meant to spin the other way.
SyncroSerge has a 140A that would be correct but I'm trying to work with what I have on hand. They all physically bolt plug and play on the alternator mount, so the amperage doesn't matter here…
Aloha!

I got a big problem, the 140A alternator has a left hand thread VS right hand thread on the 120A. I checked the pulleys, and DUH! they're meant to spin different ways. No bueno
I'm not asking for a unicorn clutch pulley with left hand threads meant to spin the other way,I know there must be a reason for the thread and rotation way. |
I got the same #07K 903 023C alternator for my ABA engine in the vanagon, but when installed it didn't work 
I thought the 140a alternator was bad so I took it to check. They told me that the alternator is working fine but those are CCW.
Now I need to get a different one!
Wish I read this post before. |
