DIY Alternator reco?

Hi
I am wanting to complete a DIY reco on an alternator. I ahve pulled one apart before and recall it being fairly straightforward, but was only dismantling to see what was inside!
Where might one go about acquiring the parts necessary for such a job? The obvious place to start is an auto electrician, but who else might stock parts for these?
It is an alternator off an RT104 18R, and without going to the garage I'm pretty sure it's a Bosch item.

Ta. It doesn't actually have to be reconditioned, it's just that I have it off the car and am pulling it apart to clean it. Figure I'd be stupid not to do a reco while I'm at it.
Not sure exactly what items are normally replaced during a reco, but brushes are an obvious one. Anyone else?

only the armiture if its rooted...in which case, if it is - its too expensive to fix. A brush kit should only be $30-$40 id think...

If it's a bosch alternator and is currently working fine all I would do is change the bearings and brushes and machine the slip rings.

A wise man said: If it ain't broke, don't try to fix it. Reco your alternator if and when it gives you trouble. I mean seriously, how long will it take you to get an alternator out of an RT104 engine bay and send it to an auto sparky?

reco alts is easy..
you need,
beefy soldering iron
brushes (maybe $5 for two? was for me last time)
screwdrivers and stuff... 1/4 drive socket and bits are good for that.
i always resolder the feild diode wires and replace some of the internal wires.. i tend to have vibration probs..
you could get an auto elec to machine the rings if you are really keen (or if it needs it).
if they are not worn, and are still flat, then a light rub with 1200 grit paper is ok.
bearings.. if these are noisy or rough, swap them.. the hardest bit is gettign the nut off at the front, and tapping the armature thru if it's rusted on.... it might just lightly tap off tho...
other than than.. there aint much to it..
my alternator failures are either brushes worn, or wires broken due to vibration. occasionally i have field diode and solder joint failures too.
pm me if ya want. i have pics somewhere..
is this a regulator/brush assembly? (the plastic rectangle thing that comes out?)
Cya, Stewart

Hey mate. check the above thread. Take the brush holder out and check the length of your brushes (Not sure if yours will be the same design though). If they seem pretty low then either do as Stew is saying or find a place that does exhange holders with the new brushes(got mine for $25). I showed the alternator to the auto elec (for piece of mind) when I picked up the brushes and he said the bearings seemed fine and the slip rings weren't too bad if I sanded them a little.
The alternator has been going fine for the last few months and expect it to last the life of the car...
