Inexpensive replacement alternator pulleys for underdrive compensation
Then it shouldn't be a big deal for you to put a smaller pulley on. Don't forget that you may need a slightly smaller belt -- although with the next size down, on such a small pulley, the difference may be easily accomodated by the tensioner.

here is how my truck moves from point a to point b:
pedal to metal, until speed limit is reached.
constant at speed limit, adjusting to varying speeds.
brake.
stop.

"pedal to metal until speed limit is reached -- or the transmission fries again..."
hahah...
she never has problems on the road.
common denominator: offroading
so, that has been nipped in the bud. til i graduate and can afford something that can be built to properly handle the abuse of christian.
one can only afford so many repairs on a wal-mart employee's pay...

seriously, ford should come out with a new model ranger.
Ford Ranger CD Edition
it would have to have sooooo many upgrades. bigger stronger everything.
the selling motto would be:
"The best choice for the video game generation of vehicle abusers... Want to drive it like you stole it? You can, and it'll keep on going..."
It would be a good seller.

Okay, I hadn't seen a charge to my account yet, so I called them. A fellow named Randy, who's the owner, answered. It's pretty much a one man operation.
He didn't charge me because he was unable to know when he was shipping. Apparently, he hates to bill someone when he's not sure of lead time. He as going to call if the pulleys didn't make it or whatever to give me a chance to cancel the order.
When I was looking around for these pulleys, it was hard to find them affordably and he says that's his problem also. Apparently, he's at the mercy of his vendor to supply him at this price -- in other words, you can get a good price if you're willing to live with the variable lead times, lol. I would say if you have an urgent need for a specific pulley, call Randy first and see if he's got it available or not.
But I have to say he's a pretty cool guy. I had about a 15 minute conversation with him talking about auto electrical systems, Ranger-Forums and a couple of other things. If you place an order, mention that you're from Ranger-Forums and maybe we can get some traction for a Ranger-Forums discount at some point, lol. He's been in the auto electrical business for 30 years, and seems to be pretty well informed.
I should have the pulley before the weekend, and I'll post how it looks and goes on.

My first vehicle was stick, and I used to drive a trash truck when I got out of high school (I wasn't supposed to -- too young; but the regular driver was an alcoholic and couldn't drive in the morning, so I was it, lol). Gave me some practice on drving stick and maneuvering in tight places, lol.
I would LOVE to drive your truck, D.! I doubt I'll wring every inch out of it -- I just want to feel it pull, lol!!!

Griggs, I thought this was kind of funny (and timely). My new 5.0 mustang mag just came in. they were doing a dyno test on an '05 Mustang v6 mustang. They got 210 to the rear wheels, but what struck me funny was one of the mods listed: "underdrive alternator pulley".
Griggs, cancel your order. It won't fit the alternator. There is a collar on the backside of the pulley that fits into the alternator. It looks like it seats itself on a bearing. The collar on the new one is 1-1/8" diameter, the oem is 15/16". The new one won't fit down in there. It will be steel on aluminum contact and the pulley will be too far out away from the alt.
I'm gonna call them and see what the scoop is.

I just got off the phone with them. To make it work I will have to grind the collar off the alternator. I haven't got the grinder out, but this looks like a bigger task than it sounds. You have to grind the aluminum below the level of the bearing and do enough masking to keep shavings out of the unit. He is gonna see what he can do about grinding it off the pulley itself so the alt will not have to be modded. If he can do this, it will be great as he has the only cost effective version of this pulley.
On the larger pulley (underdrive)- i know it doesn't fit in Griggs application, but I'll finish up the review here. It is too heavy. For those few that want to underdrive them they are doing so for pure performance reasons. There are aluminum alternatives out there for about $10 more. The pulley is 10 ounces heavier than stock. I don't have the weight of the aluminum version but I would expect it to be lighter than oem which would add further benefit.

Well, that sucks. You'd think he'd know that or ASK questions about what you have. Since I have a Ford 2G/3G type alternator like he sells, you would think his pulleys would FIT!
Same here. He was well aware that could be the case with the newer alternators after I spoke with him. It seems like the one we need would fit the older ones, but the ones he has won't fit the newer ones.
I think I can grind the alt pulley down by attaching it on my drill press and using a file while it spins. It's just not practical for me on a regular basis.

Sorry for the multiple replies here. The collar depth is not as deep as the oem pulley, about an 1/8" difference. Even if you narrow the diameter of the collar on the pulley you will still have to grind some off of the alternator so it will reach the bearing. Luckily, if you do this it appears that the belt will line up right on the pulley. I thought all this finessing would alter the position of the pulley in relation to the alt. It's still a lot of work to save a few $$'s, especially since pulling the alt may be necessary to make the mods. I think that was one of your factors to do the pulley instead of getting a proper alternator.
