Alright; goin' off for 2 days here; if 4-5 of you elves wanna' come re-assemble my mill, solve the 'hesitation', and do a little wax, I'll get over it.

Tools are out, door's open, 3/4 of a half gallon of Crown in the fridge (mixer ( or the rocks, if you have taste ) is on you.

AND FIND THAT BOLT WHILE YOU'RE AT IT!!!

And never mind that battleax Hawkeye Potts next door; she'll watch, but not much more...

Have a good Christmas.

Merry Christmas to you Schrade. Unfortunately Santa has restricted this Elf to Colorado this year but maybe the new year will be kinder to ya. Maybe Santa has some extra bolts from his ZR1. I hear its pretty quick to deliver all those toys in one night.

I found the bolt earlier today. Haven't actually touched it tho' - I have to corkscrew the light/cam about 270' into place to see it, and take screenshots and snappics, and no landmarks either.

Hydrogen Embrittlement isn't a problem with aluminum. Have you considered powdercoating the case with a high gloss powder. I've seen some that are as shiny as chrome.

I've seen rebuilt alt's from parts stores with silver paint on them to pretty them up because the case is stained just like you said. When I went to wipe them down after installation the paint came off.
As far as the coating on the field core - its there for several reasons. Corrosion resistance mainly. I wouldn't clean it off. Tyler's idea above looks like a good solution for a low buck fix.

Schrade,
There should be a little hole in which to insert a toothpick or other small round stick which holds the brushes in place and protrudes out the back of the case. That way you can pull the pick out when the case is assembled together and allow the brushes to contact the armature. Put the toothpick through the hole in the brushes case as well as the alt case. Don't need fishing line. Try it I think you'll like it.

Also, be careful using rubber as an alt terminal insulator as the original one is made from Bakelite or fiberglass and doesn't compress like rubber to maintain clearance to the case.

Rubber squeeze WAS a concern there Franke, but it's tight enough in the opening so the shank is ok. The bolt head with half a grommet is tentative; probably go with a whole one instead there...

Just saw the opening in the case rear for the tool Jxxxx

, for the brush retension @ assembly. Wondered about that as I went...

Due to the high rpm achieved by the alternator, I'm sure you can appreciate the need for extremely tight balance specs for the rotating hardware; and that includes the impeller (fan). My point is, I don't recommend painting the impeller as doing so may result in upsetting the center of gravity to (at the very least) cause premature bearing wear.

But, if you DO paint the impeller, care must be taken to assure the paint is applied (or plating, if that be the case) absolutely even. One way to do that is to spin the impeller as the paint is sprayed on, OR dipping. (It appears the paint on the impeller is laid on perhaps a bit thick(?), and probably done with the impeller in a stationary state while hand sprayed, yes?

)

Maybe you're OK, but I hope you haven't created a future problem...Just sayin.

FWIW,

P.
