72Sport and RRRAAAYYY2. Thanks a bunch guys for the direction and the hints on getting this 3G apart. Went much easier than I thought it would. Removed the pully, and the VR/brush assy. I noticed the inboard brush was worn much more than the outboard one. Remove the rear case and noticed a little white corrosion on the aluminum. I lightly tapped around the outside of the case where the laminates fit. Then used an 1/8" punch, like RRRAAAYYY2 suggested, to get the laminates and coils moving out of the case. I was surprised that all it took was just a few light taps on the punch around the case, then a couple more light taps around the outside of the case, and the assy. just dropped right out in my hand.
I need to replace the brushes, and it looks like they are not replaceable, as the wires are epoxied in place. So I will probably go to a local alternator shop and pick up a new VR/brush assy and some new bearings.
The problem I now have is that the inside ring, where the brushes ride, is worn probably 1/64" or so. Not sure if that's able to be cleaned up or not. I've heard of the armature's being set up in a lathe, and those rings being turned down flat. So, I'm not sure what my alternatives are, besides packing the whole thing up and taking it all to the alternator shop. Anyone got any ideas???
