How do you replace the alternator on a 1970 volkswagen beetle?

Get John Muirs -"How to keep your Volkswagen alive, a manual for the Compleat Idiot" and Bentleys "workshop manual". They have a huge amount of info, John Muir is a "real world" work-book and the Bently Manual is the VW "Official Workshop Manual" . It's actually a Generator on early '72's and earlier unless it's been retrofitted already I believe, but any way they are removed the same. Mark the wires so you know where they go when you get it back together. Take the pulleys off, and then the band that holds the gen/alt to the stand and then take the four bolts off of the fan shroud. The fan is connected to the other side of that panel. That whole thing comes out so move what ever you can to be able to pull it out. When you have it out look on the other side and in the middle of the fan is a BIG nut. Take that off and the panels come loose. If it's an Alternator then remember how the panels are assembled as they also are set a certain way for the cooling of the Alternator.
