I've had a few alternators apart before, but quite a while ago and never a 3G. I got the pulley off, the front half of the case, and the regulator, but I can't get the stator and rotor assembly to come off the rear half of the case. The stator, rotor, and rear case all seem to move freely of each other and wiggle a little bit but I can't get them separated and I don't want to pry for fear of breaking something. Any tips??
 
Remove the pulley with an impact wrench. Remove the voltage regulator. Note the little round hole in the vr housing. When reinstalling use insert a paper clip in the hole to hold the brushes up. Remove the 3 screws holding the case together and the nut for the battery lead and the single wire connector. I believe the rear half of the case comes off fairly easily. The one I reclocked had the laminates jammed in the front housing. To remove them I supported the front half of the case on some blocks of wood pulley end up. I took a Craftsman small screwdriver 1/8" blade and inserted it between the case and the wiindings. Don't scratch the windings. I placed the blade of the screwdriver parallel to the outside of the case. I tapped on the handle of the screwdriver with a small hammer. I moved around the circumference of the case until the windings dropped out of the front half of the case. go slow and easy its easy to turn them to JUNK real fast! James:canada:
