    Default Non Bosch re-manufactured Alternator Must see inspection...

    So I got a reman because I didn't want to wait on the shipping and return for core charge for a genuine Bosch reman unit. I will now go for the genuine Bosch which I should have in the first place.

    This is right out the box. Missing bolt no biggie I can replace it with one from my old one. Noticed the stripped ones on the front that hold the bearing. I guess they didn't need to replace it because they were unable to remove it. SO I have to remove the cover to replace the bolt / stud thing.

    This thing is covered in ground metal like it was stored under a grinder or something.

    Slip ring is .012 off center, that should last a long time combined with the worn out brushes.

    They are unable to send a replacement because they have none in stock.

    Inside looks fine. Not sure what to do yet, emailed Bosch and waiting on a reply.

    Now compare the rectifier connections to the other 'rebuilt' one.

    I would use the plastic cover from the old one. In any case we can clearly see the differences between non-Bosch and Bosch reman alternators.

    I can but waiting to hear from Bosch. With their remanufactured alternators you get road side assistance and towing up to 50 miles for 2 years.

    Well, wow. Roadside assistance?
    Wish I knew that when we replaced the original Valeo Alt in our 07 550i in 10/19. Bought a used factory Valeo unit online and it arrived with a cracked rear cover (I didn't notice.) Installed it and it was overcharging like a beast. Removed it and noticed the cracked rear cover, removed it to discover a cracked regulator. Ouch. Seller gave us a price break but we needed the car in the mean time. Installed the old regulator on the replacement alt and it was fine for months. Should have just let it ride but put a new Valeo regulator in it and it was acting up. I don't remember how we ended up but my son and I put that alternator in 3 or 4 times. Not fun in a V8 E60. Not a bit.
