Alternator

Ok what is so special about the SC alternator that it costs 180 bucks and no one can get it in stock for four days? I would think that it was a standard ford part.

Well, one huge difference is that there are 8 ribs on the pulley instead of 6.

.. dont know what Auto parts store you deal with, if I needed a SC alternator they are usually in stock or it takes 1 day to transfer from the hub.

Of course you could get alternator off any 3.8 Mustang from 94-00 and just change the pulley.

Or.. if the fail mode is it quit charging at over 1500 rpm and starts charging when you tap the case, then you could go to NAPA and spend 15 bucks for a brush set.

I will never again buy a 'rebuilt' alternator.

I do it just because I still want to know HOW and WHY!!! Quit learning=die. Be informed as to WHAT, rather than learn,=brain-dead already.

I have checked at Advanced, Autozone, Orielly, Pepboys and napa nobody has one with out a four day wait. I ordered it but it is going to cost me an additional 60 in gas driving the dually for 4 days.

Or you could hop on rockauto.com and get one shipped to you in a day or two for less than what these retail stores charge (depending which alt. you choose).

That sucks.

There's not an independent rebuild shop around?

We have three at least in Shreveport-Bossier - I walk in by 10 AM with the old alternator, for under $80 I can either get my pulley put on one he's got on the shelf or come back that afternoon with mine rebuilt by someone who knows what they're doing and how to do it.

'cuz it's like 'Rocket science' Two different people in my little burg got into the 'rebuild' biz in the last twenty years. Then got out because it's not the rebuild that's expensive it's the logistics.

I just explained your likely fail.. tap the back and it charges, then it's a brush set and cleanup. That's if it's a Motorcraft.

OR go to junkyard, get same OE part off 3.8 stang and change pulley.

Look at Rockauto's cross check list.. you are waiting that long for a rare 8 rib pulley on a common OE part.

__________________________________________________ ___
For posterity.. meaning future readers:

You want the Motorcraft 130A part. High priced? Think Sound system upgrade to figure out why.

Most scrapyards sell used for core price or slightly less, plus core. Last one I bought.. several years ago..their core was half of part store core.

Usual fail in the three different series {all motorcraft} alts I've dealt with were worn brushes.. about 150 - 190 Kmiles. Light first comes on at speed, may come back to charge at idle. Tap back of housing will start charge again. Just like the starter trick.

Major parts of alt:
1. Stator/ diode assy - no point in fixing it unless you see a broken wire connection.

2. Front housing with bearing. Got industrial /commercial connections? Bearing replaceable at half price of on line ordering as civilian if you do.
- rotor... only bad if brass rings are shot. seldom shorts in windings, never seen bad rear bearing surface {out of about ten}

3. Rear housing:
- sleeve bearing. usually good
- brush set - available rockauto, napa about $15
- voltage regulator, avail rockauto napa about $45

Of course for SC owners, like in this thread, the issue is the pulley remove/ replace.

I'll still stick with getting mine rebuilt by the pros (locals). He's faster and cheaper than I could do it.

If all else fails get a bigger hammer!
