This process has been frustrating beyond imagine. Posting some info I've gathered if it will help others.

The back of my alternator shows p/n F00M145311 on the voltage regulator.

Christian Caudle of Maniac Electric Motors has been very helpful and gave me the following:

"The F00M145311 LIN Function Fits 0124525060, 0124525061, 0124525521, 0124525522, 0124625024, 0124625025 (including our # 11363). The 11488 looks identical to 11081 and if tried to use 11081, it would not be compatible using Regulator F00MA45211."

Continuing, "[The clutch pulley] has a 65-80K mile life span. But might last longer." I did not know this, so it will have to be an item on my radar, if we keep the XC that long. I'm ready to can the thing!

Maniac Electric Motors: "The only warning our catalogs show is that the identical alternator 0124625003 will not work."

0124625003 appears to equate to 11081, which Maniac Electric Motors says is not the correct part.

RockAuto, Advance Auto, Auto Parts Warehouse, and a host of others who offer a less expensive option (including Maniac Electric Motors ???) all say 11488 or 11081 are the correct alternator. But from everything I can find, this is incorrect.

What I find terribly confusing is that 11363 is not described as a replacement for my alternator. 11488 and 11081 are listed as replacement parts. It would seem that the alternators are interchangeable, but apparently this is not true. So do I take a gamble on 11363? Maniac Electric Motors says it is a direct fit based on the Bosch order number on my alternator.

As of right now, I am going to try and replace the pulley. If that's the only problem, I'll be back on the road. If not, Rock Auto is sending me an alternator; I just don't know if it is the correct one. It should be 11081 because that's all they carry.

I also have a call into Bosch tech support to see if they can help me sort this mess out.
