I want to take the case off my altenator to polish or paint it. How do I remove the case the right way.

You're going to need outside torx bits I believe it is, that and being extra careful with pulling it apart. Ive been wanting to do this with mine as well, and I dont know if it already is, but Ive got some heat sink compound for the regulator as well.

It whines a lot, but I like it.

there are two long bolts that go from the back but be carefull there are things that are soldered together. o and you have to take the pulley off.

if memory serves, and they are the same as they were in '96 you use an allen wrench and a box wrench, and it's left hand thread

Are you serious? Can you get a box end in there? Enough to back off a bolt?

Well heres some pics to refresh memories.
Do you take the little bolts off the black plastic piece in the second and third pics?

that will remove the voltage reg.

I mean all the bolts in the surround on the second pic.

well those atach all the little things so unless you want to tape it off yes it has to come off but other wise the case should come apart.

you dont need a box end and a torx bit if you have an air powered ratchet. and no, i dont believe that they are reverse/right hand thread. one should be able to hold the serpentine pulley and use the air powered ratchet to remove the nut.

Can anyone verify which way the threads are because I just broke a torx bit trying to do it as regular threads.

I've never seen any delco that used reverse threads on the pulley nut.

do you have access to an impact driver tool? (kind where you HIT the tool with a big hammer, and it turns the oposite end? it's gonna be on there TIGHT so it might need an air ratchet or impact driver tool

Yeah I have an impact wrench, but its in the garage and its like 2 degrees out so I will try that when it warms up a little. Thanks for the help and is there anything to watch out for when I pull the case apart.

I want to dress up my alt. I went to an alt shop and and they have one that has been sand blasted and the other side was painted a gray cast aluminum. They want 91 bucks completely rebuilt. I would love a chrome one, but durability and cost wise, I don't think it is possible. Would this be the best route?

Would I be able to sell my original Alt?
