Did a search - couldn't find the answer I'm looking for.....I'm hoping you guru's can help me.

I am in need of a dual pulley for my OBA set-up - apparently there isn't enough belt contact on my alt so I am needing to put two belts on to fix the problem. I am tired of running out of juice and I need my OBA! :crybaby2:

Help! What type of donor vehicle will I find a dual pulley that will fit a '90 YJ alternator?

V6 Dodge dakota's from the late 80's early 90's had a dual pulley on the alternator.
I don't know if the 4.0 alternator is the same. But they are both made by Dodge.....

i feel yo pain or slippage in this case cause i have the same problem, only thing here is i assume you are then running to the crank pulley but isnt the other groove for your power steering or do you have a 3 groove pulley?:question:

try Lordco they can huck ya up with one are you runing the GM Delco style alt?

also my truck came factory duel belt setup (2 on the alt and on the cranck and the water pump) :confused: I guess at international they thought if one snaps thers a second one still runing everything :smokin:

so if ya go to the wreckers look in an international truck

Standard Truck Parts have lots of IHs and very cheep prices

Heyya snacks.....same problem huh? Yah I am running to the crank pulley - and my current pulley is only 2 groove. Only way out of it as I see it, is to use a dual pulley and add another belt, that should solve the slippage problem and slow charge.

AIRZUKI & Chief - thanks for the info. I will call the wrecker and see if I can track one down there. Didn't really want to pay high Lordco prices for a new one, but will if I have to.

Chief - yes I'm on my SECOND GM Delco alt :mad:

So are you looking for a dual groove pully for your GM alt? I will check through my junk when I get home tonight to see if I have one. If so, you can have it.

EDIT: Sorry, I checked & I don't have one. I thought I did.

hey, MB. i just did (more or less) the same thing requiring the use of a dual row pulley for my Sammy.
lots of people chimed in with "oh it's easy, just grab a pulley off a "........." and you're done.

of course the model they said would work wouldn't, because i needed a V pulley, not a flat or serpentine type.
then there are the issues of bolt hole spacing, pulley thickness, diameter, etc.etc.

i spent quite a few annoying visits to far flung junk yards looking for a pulley that turned out to be NOT what i needed:mad:

thankfully, one of the board members here hooked me up with what i DID need, for basically free-only shipping/duty/brokerage/tax etc. (which really SUCKS btw)

bottom line- take *some* "oh it's easy" advice with a grain of salt.

you are in a better position than I, because of a much more popular application. lots more choices for you!

have fun blowing stuff. err i mean blowing up people's stuff. ahh no, ahh... getting good use of some of that hot air under your...ahh. hmmm.... well you know what i mean.:flipoff2:

MJF - thanks for checking - I appreciate the offer AND the effort! :)

Uzi....thanks for your "advice"....lol......I guess I'm going to have some fun with this - damn OBA - can't live with it...can't live without it! grrrrrrrrr!

I will go with the Dodge Dakota suggestion from AIRZUKI - if that doesn't work - then its back to the drawing board!

Thanks guys! :D

If you think it will work for you, I just got a parts truck that has the two groove pulley on the alt. It's an 88 Dodge 360(?). PM me if you want me to pull it off & send it to you.

I have no idea if it will work for your application or not. I just noticed it had the two groove pulley
