How to remove alternator pulley???

[Baconbit]

How do I remove the clutched pulley from a factory alternator?? I have a new alt I want to put it on right now, help!

[Blackmobile]

Sorry but you're gonna need the adapter to get it off.

[Baconbit]

Can I just run the standard pulley on my high amp alt I just got?

[myrodr]

i think you can run standard pulley with no problem

[Spectragod]

Most shops or tool trucks have the tool you need, either buy the tool, pay someone to change it or run what you have, all will achieve your goal.

[fastblackmerc]

You can run a non clutch pulley. No harm will come to your MM.

There is a special splined bit that removes the pulley as its screwed on, if you remove the black plastic cover you can see the splines the special bit goes into to unscrew it, check with a alternator repair shop they can do it in a few seconds!

[Baconbit]

Well I got it all hooked up, 200 amp alt with a Stinger 200 amp circuit breaker in line with it in 4 gauge wire from big 3 upgrade. It runs great but when I go WOT the voltage drops low and the lights dim then in a few seconds it goes back up. What is this??

[MOTOWN]

Do you have a tune on your car?

[Baconbit]

Yes from Mo.

[MOTOWN]

Yes from Mo.

I figured as much, most tunes turn of the alternator at WOT, what your seeing with the lights briefly dimming is normal.

[Baconbit]

Ok thats good to know then. Thanks Motown.

[Black_Noise]

stupid splined junk, I was unaware of it when installing the trilogy, that was a 24 hr unexpected hurdle, but justbob came through on it for me.

No problem bud:bows:

I am switching from a 6-rib to an 8-rib setup. My alternator pulley has the spline clutch that requires the special socket to remove the pulley. Interestingly local shops/stores don't have it and online places don't identify these as Ford items. Can someone confirm the pulley shown here for Mecedes Benz, Audis, VWs vehicles is the correct tool?

Yes, that is the correct one.

Jim, you stud! I hadn't even finished editing the pics and you had already responded. Thanks again.

An air chisel works just as good to remove it if you do not care to save it.

[Jeronimojc]

Lol. Good thinking. I saw an earlier post where you mentioned that.

Some other local guy said he'll buy the socket from me when I am finished so I'll go that route.

Thanks.

You can also rent the tool at a local parts store. My Autozone store has it in stock.

Rent the socket..... if he breaks it he buys you another one.

If the tune shuts off the alternator at WOT and there is no clutch pulley does that mean the belt is slipping and will wear prematurely?

I ask because I have a replacement alternator installed and the original rebuilt on the bench wondering if I should re install it as I have a Lidio tune.

[MERCULES]

I meant to mention the aftermarket alternator I have installed does not have a clutch pulley, I have since had the original rebuilt with a new clutch pulley and wondering if I should remount it to avoid slippage at WOT?

I maybe wrong but......

The clutch has nothing to do with slipping at WOT. It to prevent the belt from making noise under deceleration

[Zack]

The clutch has everything to do with preventing noise on up shifts at WOT

I have a regular pulley on the beater and it squeals like a pig when I shift at WOT.
Doesn't bother me though

[SOSA03]

AutoZone has in loan-a-tool

[Jeronimojc]

I tried that first. Every auto parts store I visited didn't have the right tool. Thanks anyway though.

They are all over eBay for like $8. Never understood the rarity factor.

Only rare when you need one

[Jeronimojc]

Yes, Ebay. The problem is most of these items don't say Ford. I bought one for $11.

How do you keep the alternator from spinning during removal?

As far as the clutched pulley goes, the German part that costs $75 is the way to go. I bought an alternator from O'Reilly (failed in Yellowstone NP, did not have many options) and the clutched pulley was inferior. It makes all kinds of irritating racket when the engine winds up.

I'm going to buy one of these tools and put my good German pulley on it.

Can you loosen up the assembly while the belt is still attached?

I didn't realize the entire thing comes out together. I was hoping to reuse the clutch. I guess I'll end up with a "squealing pig" too.

What a silly little "tool" this is. 40750

A clutched 8-rib alt pulley sounds like a custom fabrication. I guess anything is possible. Having more belt grip may reduce the squealing of a solid pulley.

[lifespeed]

Just got the $11 dollar splined socket and swapped my O'Reilly clutched pulley (which was actually labeled as the German INA part!!) for the one I bought from a local alternator shop. The main INA-XXXXX part number was the same, but a couple numbers elsewhere were different. O'Reilly part was cadmium plated, alternator shop piece was painted black like OEM.

The annoying rattle went away, so it was a noisy clutched pulley as I thought. Weird . . .

I know this is an old post, but I gotta change pulleys. When I bought a new alternator I didn't change pulleys. The chirp drives me crazy, on the non-clutch pulley! So I bought a new clutch pulley, and the tool needed to take it off. The problem I'm having is, what do I stick in the middle of the tool? All the videos I watch on youtube show a shaft, or extension, that goes through the tool, into the alternator. These people keep showing a kit. I bought the tool that everyone was showing, in this thread. Now I just have to figure out how to get it to work. Oh, and I don't have an impact. Any help would be greatly appreciated.

I was not aware the alternator shaft had an internal key (allen?) to keep it from spinning. I think most use an impact, which is what I did as well.

SOB! I guess I'll have to find an impact then. Thanks for your help.

[justbob]

Yup.

I used a impact at work today, and it took me less than 5mins..

[vegasmarauder]

Quick notes on the cluthc pulley. I have seen two MMs with "bad" alternators (red light one, no charge) that actually had bad clutches that no longer held. Conversely I found one MM that had a siezed clutch that didn't slip (the belt chriped at WOT).

There is a Chinese knock off replacement being sold out there that will last about one month to a year before it seizes or slips. The German made one is the way to go. Easiest way to tell? The Chinese one sells for $20-45 online and says "Made in China", the German one is never less than $50 and says "Made in Germany" or "Germany" on it.

And the MM alt shaft does not have any kind of internal spline or key to use to hold the shaft still like some repair manuals or videos show. You have to use and impact to remove it.
