Smaller Alt. Pulley.

flareside_thunder · Aug 9, 2010

I need to know what smaller pulleys will fit on our (Gen 9) 95 amp alternators? I just need this junkyard upgade until I can do a 3G conversion, this 30 amp draw fan is killin me...and my battery. My alternator is on it's way out anyways so I'm having it rebuilt and turned up tomorrow. But, wouldn't hurt to have a bit more spinnage. Thanks guys.

What year is your truck? If gen 9 then you should already have a 3G alternator...

Go to your local auto electric shop. My guy hooked me up with a bolt-on 130 amp alternator that has a lot of juice in the low rpm's that's popular with the snow plow guys.

You can also get them to make it marine grade for boats which is a plus for heavy muddin.

The Taurus alt is bolt on? What year? And Chris mine is only 95 Amp...yes it's a 95.

The 95 amp alternator is 3G alternator. 2G alternators had external fans on them.

Ah...so...why did you have to do a conversion? Looks like the Windstar alt may be a direct swap as well.

Skandocious · Aug 10, 2010

I didn't convert anything-- I just upgraded to the 130amp. Only problem was that my particular truck uses a side-mount alternator and the taurus uses a pivot mount, so I had to swap the guts from a good pivot mount unit into a garbage side mount unit's housing to use it on my truck.

flareside_thunder · Aug 10, 2010

Ah gotcha...still researching but it looks like the Windstar may be promising....

Skandocious · Aug 10, 2010

Just make sure it's the right case-- there are 3 different styles and 3 different regulator clockings:

Case styles:

Clockings:

The clocking can be adjusted after you buy the alternator by removing the case bolts and spinning it, but it's just a pain in the butt if you can avoid it by getting the right one in the first place.
