Alt Pulley Removal

[cherrington17]

So i got the pulley from EXCESSIVE AMPERAGE, and went to change it... and it occurs to me... i have no idea how.

I'm guessing i have to remove the alt. since i don't see how i could get it off in the space provided (espicially with an impact gun) and in that case, if i'm taking it off, i mind as well take it over to a parts place and have them swap it.


But... (incase anyone else searches)


I read that with hand tools (not an pulley puller) you have to take the nut off, while holding the center shaft with a hexkey. how does that work? they are inside the current pulley? if you put a socket on the nut, how would you get a hex key inside to hold it??? :huh: i'm really missing something here.

Take the alternator off. Get an impact wrench and a very large slipjoint pliers, wrap a thick piece of rubber around the pulley to protect it and hold it with the pliers, remove with the impact.

any idea what size socket that requires? its bigger then 19mm....

I use a 15/16 in., I think that's 24 mm...

So what do you think of the new pulleys? Little lightweight thing ain't it :)

[cherrington17]

can barely tell i'm even holding the thing. :lol:

Yeah, now just imagine how much of an impact that will have of the bearings... Less weight ='s Less stress ;)

[cherrington17]

lets hope so

[CBLOHM3400]

remove alt from car a put impact on nut and hold with hand never had one try to soin holding it with my hand
changed probaly 30 of them

[cherrington17]

yeah... the problem is, i don't have the right socket size. so i'll just run it over to the parts store, have them swap them.

[cherrington17]

took it to Autozone, they swapped it in no time. also picked up some dielectric grease, just to be sure i won't be doing this again soon.



looks like at full boar, i'm pushing 15.1 Volts now... i'll update after i'm out driving and it idles down, to see how much higher it'll be.

What was the before reading?

[cherrington17]

like... 14.8


i'll also add, the alternator is from www.mralternator.com 160A (have the 3.4L) the the old pulley weighted like 1lb. :blink: the new one was like... 50g? :lol:

[cherrington17]

when i idle down at stop lights.... i hit like 14.8...

so good so far...

[Ryan from Ohio]

Well the weights about meaningless. I mean you DO have a belt with tension on it, therefore its weight.

[cherrington17]

i'm just stating. its VERY lightweight, in comparison

[CarGodz]

The weight may not seem like much when you consider the tension of the belt, but it does have an impact on the bearings and will have less stress on them.
Glad to hear you're happy with it and that it does what it's supposed to do for a higher charge at idle on a different alt than Excessive... I believe you are the first to try one of these on another brand of alt and if you get a chance I'd love it if you could send me a pic of it.

[cherrington17]

definitely can.

don't be too surprised, if it looks like a slightly shinier pulley on a normal looking alternator. :lol:

[CarGodz]

Well I know what they look like since I'm the one that manufactures them LOL
I'd just like to have a pic on different style for when we go to market them to other companies ;)

[cherrington17]

here ya go. (i have higher res 3MP pics i can email you, if you want)

one still, one comparison, one moving.

[cherrington17]

yes, i am aware that my alt doesn't have the front bolt on it. it doesn't line up, and its been like that for like 2 years now. the belt and 2 rear bolts hold it just fine. (thankfully)

Yeah, I'd love to have them:
email: cargodzracing@yahoo.com
thanks :cool:
And I LOVE that you got that old new shot, cause that old one IS an overdrive pulley too (obviously not as small though, but that's a given)... Verry Cool! :coolio:

[cherrington17]

email sent. :thumb:

[CarGodz]

Gots and thanks again :)

[cherrington17]

your welcome.

do i get incentive for being a partial advertiser? :lol:

[CarGodz]

Well hit me up the next time you need something and I'll make sure you get a nice lil break ;)

[cherrington17]

:lol: i was kidding. i'm glad i could help you out. its not like the picture is something specific. i don't have a show car.

[CarGodz]

Maybe not, but the shots turned out great and the one with the side by side may have me selling them to Mr.Alternator :D

[cherrington17]

NICE!

and after finally getting a decent drive out of it (haven't driven much since installing) it normally sits at 14.8, idles down to 14.1 and like stated before, at WOT it stops at 15.1

i'm impressed. Good work!
