Is it really as simple as just getting a smaller pulley for alternator?

That's not what she said.

Cute. You’re in rare form today, eh?

? No, it is not. Both specs says exactly same diameter. 2.37" OD (60mm).

Pulley is smaller.

Well theres the proof. Finally someone with one smaller than yours...

Could be my original pulley was the larger one. This pulley jumped my output well into the green at idle. I'm going to have to get a shorter belt though. It's squeaking a good bit now.

Interesting. Specs say exact same. Did you get the alternator from me? Sold a bunch recently, apology I can't keep track. If so, I have a replacement lower brace that allows you to make the stock serpentine belt system "adjustable", to set the tensioner anywhere you want it. I'll send it to you for free, if you bought from me.

If not, then I don't know where the pulley in your pic came from. I'll check others I have here to see if they are similar.

Thanks for the update!

I tried to thank your post like 7 times bro, but it would not let me.

Yes, it’s one of yours. We tried a Delco first and it didn’t do what we expected so you sent me the Chinese one at no charge. I forgot to give you props here for being such a great guy to deal with. My apologies.

And no need to send the arm, I bought a shorter belt. I’ll post the NAPA part number later for anyone interested.

Sitting here thinking back through the fog. I had a pulley when you sent the alternator. I didn’t get the first pulley from you. It came from NAPA.

All making sense now, thanks.
