8-Rib Alternator pulley for Motorcraft 6G Alternator - HELP!

[o2sys]

For those who upgraded to 8-rib, please tell me the EXACT what pulley you used.

Been searching and yea though there is a ton of info everything is using something different.

I'm so tried of this conversion wish I never started. The two clutched pulleys I sourced touch the alternator's housing.

Outer most left is Oversize Clutched 8-rib Pulley, then is stock sized 8-rib clutched, and right is stock 6-rib:

Will this alternator work?

IIRC all I did was use a Navigator alternator pulley. It wasn't clutched.

6g alternator doesn't use a clutched pulley. I sold my 8 rib kit but there was a Navigator 8 rib pulley in there for the alternator (my alternator was a Denso with a different size drive shaft). Sam or Steve can get you the part number.

I think my Motorcraft is a 6G (2007 GT) and the pulley I pulled off was clutched.

If that's true then you have the only one.

Wasn't 6G/??? a 2010+ thing?

I know I have the "shitty" alternator. 2008.

 

[o2sys]

I maybe misinformed then

But do know that the pulley I pulled off was clutched.

If that's what I have, I can certainly go take some pics of it for you guys.

Skwerl?

Yup, you ended up with it. The alternator pulley you have is the one for the 05-09 Mustang alternators.

To the OP - would dismantling the alternator and relieving the housing leave you with a pulley in line with the rest?

 

[o2sys]

You me grinding down the housing so the pulley doesn't touch?

 

[eighty6gt]

Yeah. It's almost finished now.

Ford part number GP-720.
No clutch and fits properly

I switched to 8 rib about 2 years ago. Had to make a spacer to locate pulley same distance from alternator as stock 6 rib pulley.

 

[o2sys]

I ended up cracking the alternator housing by testing different washers so I went to a local alternator shop and bought a reman unit and they had a OD 8-rib non-clutch pulley and put it free of charger.

Haven't ran the car yet but quick startup it was good.

Where did the alt housing crack? In the rear by the support?

 

[o2sys]

No the front by the shaft.

 

[crownaviation]

I have made shims in the past but made sure the ID was the same as the shaft. That is crazy that the case cracked tho

 

[o2sys]

I think the pulley rubbing weaken that area and I guess the washer I used had a slightly bigger OD and my using an impact gun and tightening the pulley it jammed it in and cracked.
