Alternator - rebuild or replace
Hi
Just pulled my alternator as it quit on me.
One brush was shot and the other was down.
My question is this. There is a channel in the copper of the shaft of the alternator that is about 1/16" deep. I'm not sure how much contact surface is built onto the shaft so who might know if it's okay to just replace the brushes ($5.00) or do I have to replace the whole alternator ($285)
Thanks in advance.

if you have got about 150k miles or so, then the wear to the commutator is probably excessive. i have cut them down on a lathe and polished, put in new brushes... you wil bo o.k. for a few months. It about time for a new commutator... thats a lot of work, just get another alternator. You can get a better deal than $300. I bought a takeoff on e-bay from a guy that builds ambulance and puts on BIG units. It cost me about $100. a couple years ago.

Yea, my truck has ran so good it's unbelievable.
I know I will be rebuilding it soon.....I guess. Anyway, I went and looked at a used 97 for sale and noticed the engine running and could actually see a side to side shake in the engine.
I then went home, opened up my hood on my truck looked at it and I could not detect ANY movement at all. Makes me wonder if at the factory someone may have "blueprinted" my engine as an experiment.
Oh yea, I'm still on the original EGR, which I would have thought it would ruptured by now.
