Thanks Herb and Spook. I did find some screws at menard.com, our local hardware (and most everything else) store. Happy to see more metric hardware available these days in general hardware stores.

I had trouble with one of the screws like Herb mentioned but a punch on the edge and a few wraps with a small ball peen hammer did the job of loosening it.

Any ideas on cleaning up the slip rings (commutator) without seperating the halves of the alternator? I have several that aren't too badly grooved. The 80A slip rings are in much better shape than the 100A slip rings. The bearings are amazing in these alternators even with the strong tension on the belt. I have never had a bad bearing.

I think replacing the brushes before they are too short helps prevent heavy grooving of the slip rings.
