For Special Armoured Vehicle!
Now that my S8 is running properly (gearbox) I can attend to the little things.
The alternator is fairly noisy at present. I'll be pulling it off asap to have a look and see if I can replace a bearing or whatever is making the racket. Having looked up the part number, apparently my car has an alternator which was specc'd 'For Special Armoured Vehicle' according to ETOS and ETKA.  I was tempted to look for a spare alternator to just swap over rather than have to pull it to pieces several times but something tells me that I'm not likely to find one of these on ebay! Is this more common than I'm expecting? MG

It gets more funky...
Apparently it's the same part as fitted to a Gallardo 2004-2008!! I don't like the price tag on that one though... are you rich?? MG

Wow! That's more than the crazy water-cooled one on Phaetons, some Audis, and Touaregs!

First drive back home in the S8 yesterday
 I got a bit carried away last night and pulled the alternator off to have a closer look.  It came apart ok and I found out which bearing needs replacing along with the dimensions and part number for a replacement. Just need to find someone that has one now. I'll be changing the regulator in there too as the brushes don't have much life left in them.  The problem bearing is behind the pulley. I managed to carefully remove the dust cover, clean out the old dead grease and clean out the crap with brake cleaner. Unfortunately the outer race is worn so I refilled it with fresh grease, dust cover and put it back together. It's a little quieter but not much.  Part number: SC03A21LHA.

People have been finding it difficult to source this bearing... Sounds familiar! MG

You could try Googleing motor rewinds. These are people who re-build all sorts of eleccy stuff. I never bought new starters etc for my trucks, just had them rebuilt, as good as new.
They must have loads of parts in all sorts of sizes
