Alternator

So the alternator in the truck crapped the bed. Found a bosch replacement marked as being for a 94. When it arrived I found that it has a pulley for a serpentine belt. Now, I can change pulleys over, but if I remember correctly the OBDII motors are reversed rotation from the OBDI motors. What difference, if any, will this make to the alternator? I really don't want to go through the hassle of sending it back, and I REALLY don't want to have to use a Marelli again.

Thanks,

Tony

Bosch Alt Install guide and tips

Dude, I got this from the RN bbs. This guy has his stuff together.



Regards,



Solihull





Most will have seen my how-to page using a late model VW Bosch 120 A alternator. For those that haven't seen it, here is the new URL.

http://www.geocities.com/erdiaz.rm/Rover/bosch.html

I updated the page to correct some info and changed the URL directory.

Just yesterday on my B-day, I found another 120 A Bosch alternator at my local self serve auto salvage yard. Paid only $24 which included a $3 core charge. This alternator is a Bosch remanufactured unit. Both bearings were noisy and they must be replaced. Bosch chose to install cheap Chinese made PEER brand bearings. The seals hardend on the rear bearings, so I'm looking to get some quality name brand bearings.

Heres the URL with a how-to on opening the alternator. Covers the following: bearing replacement, voltage regulator, rectifier assembly, and slip rings.

Ok, apparently thepartsbin.com has no idea what they're doing and have now sent me 2 alternators for a '94 disco (not the same as a '94 90). Anybody know where the best (cheapest) place to order a standard 100 amp alternator for a 94 90 is? My local rebuilder isn't too hot.

Thanks

Tony

Tony, looking at the Autozone and Advance Auto sites, it looks like they've got Worldwide and Duralast alternators for $200. I know that Advance carries Bosch but they don't list that they carry one for our trucks. Incidentally, the Boschusa.com website lists part number AL9346X for the 100 amp-er

I put in a mean green alternator and I have been very happy (about 1 year ago or so) for my 94. If I were to do it again, I would. Why pay more for less? My alternator puts out about 200A or so.

FWIW, I've heard Bill Burke speak highly of the PPW. Can't think of a more qualified source. When I get around to upgrading I'd probably go PPW or Mean Green.

Do the MG alternators that are being used on the Defenders have a cast front face or a machined aluminum front face? And are there seperate adaptor brackets ( two pcs of flat bar and two round spacers)? I installed mine about a year ago and nothing seemd to fit? Since then the bracket cracked and MG sent me a replacement which looks nothing like the original? It would be a huge help to know if anyone had a simple bolt in install and what the bracketry looks like and how it fit together?

I have used their products on another vehicle and it seems to be about the best on the market, but I haven't had much luck with it on my 95 D90..
