GM Alt.

Rocfrog · 10-27-2008, 10:06 PM

Ok so I was given a GM alt. by a fellow Zuker and I went to put the pulley off the zuk alt on the GM one and the hole in the zuk pulley is too small! So I tried one of the other zuk alt. pulleys that I had and same thing! So do I possiably have the wrong GM alt.

nope you have the right alt. Just use the pulley off the GM alt.

Rocfrog · 10-27-2008, 10:19 PM

DOH!!! That's what I was afraid of, he didn't give me the pulley with it!

billsbar · 10-27-2008, 10:30 PM

I should have one if you can't come up with one. Are you running a V-belt
(1.3) or a flat belt (1.6) style

Rocfrog · 10-27-2008, 10:46 PM

V-belt.......

I'll have to see if I have any laying around in my 350 parts boxes. i could always take the one off the suburban but I don't want to do that.

I'll let you know what I find. Thanks for the offer!

I went to the alt/starter shop and traded my serpentine belt pulley for a V-style.

Rocfrog · 11-11-2008, 03:24 PM

Ok well I did some digging and found two GM Alt. pulleys in my collection but I don't know if I can use either one. Please help.

Far left is a serp belt GM pulley, next one is a "V" belt GM pulley and the far right is the stock Sami pulley. Now I think I can just use the "v" belt GM one but the groove is slightly different between the Sami one and the GM one does this make a difference???

DreamCrusher · 11-11-2008, 04:21 PM

It didn't make a difference on mine. I am running that GM V pulley.

euby · 11-11-2008, 07:49 PM

X2 .....I'm using the GM pulley...no worries

billsbar · 11-11-2008, 11:24 PM

I'm even running the GM serpentine pulley on my 1.6 flat belt. It's wider then the belt but the groves line up just fine. Zero problems

That was going to be my other question.....

I do have all the pulleys to swap over to the serp. belt but when I put the Sami belt up to the GM serp. belt pulley and didn't know if it would work.

So maybe I'll swap it all over and run the Serp. set up.

If you are running a gm alt, use the smallest pulley available. The rigs these come out of like to idle around 1000rpm and that;s were these lats put out there idle power.

A lot of guys have problems with the battery discharging at idle because the alternator isn't spinning fast enough (zooks like to idle between 700-800 RPM). I have a lot of local friends who have removed their GM alt because it won;t put enough juice out at idle. Using the smallest pulley will really help.

Whichever route you go use a small pulley on the alt ;D and really insulated the power output terminal. on some installs it is very close to the engine mount. You don't want it to short out if the engine torques ;)

Nick, Thats the set-up I'm runin on mine. The smaller 4 rib belt runs just fine on the 5 rib gm pulley. I never had any issues with it.

And I also ran the gm v belt pully too with no issues either from it being a little different.

bigjoe · 11-14-2008, 12:18 AM

old late 80s v6 camaros have 4 rib pulleys matching the 1.6 belt, thats what i run on mine. if you see one around at a junkyard or whatnot they work.

skyman · 11-14-2008, 08:02 PM

I think I am running a 4 rib belt on a 5 rib pulley for power steering it's working fine...and I am not easy on it (the eninge)

If that helps.
