Alternator Options? AL116X is nla

[Paul7002]

Ordered a new (reman) Bosch AL116x from Summit.  Was on back order but now they advise it is NLA.  This the e21 internally regulated 55 amp unit I think many of us have been running.  Other easy bolt in options?

318i e30 version is 80 amp I think

I use the AL41X which is 65 amp with internal regulator.  It took an assortment of spacers to get the pulley to line up perfectly.

Check this site http://www.zeebuck.com/bimmers/bmvseite/ for details on installing the 80 amp 318i alternator. I did it and it works great.

I have a new AL46X alternator (80 amp) which I bought to replace a not defective alt. My bad. This alt bolts right to the 02 motor if you have the right parts. I say new because although it was sold as a reman, it obviously has never been used- a common scenario, I understand with Bosch remans.

In order to not break any rules on the board I am not going to say it is for sale.

Thats a bummer if the AL116X is going bye bye.  I am uncertain if any other Bosch Alternator will just "drop in"

Higher output alternators fitted to later E21(?) and early E30s(for sure) are bigger and the mount boss is slightly wider.

You need the mounts off one of those vehicles.

I did find possible AL116X clones/non Bosch on Amazon.   Remy, Delco

I've got an E30 high mount bracket, I'm going to pop on an E21 low mount alt in the next week or two.

Anyone know what’s involved in mounting the higher output later model e21 alternators (eg AL49X) to a 2002tii? Wondering if the lower mounting position of the tii helps...

[theNomad]

The lower mount may or may not have the same width as the e21 alt. May need to shim or file the alt. 

The e21 low mount bracket and alt is a no go for the e10, but the tii mount puts it a little lower than the e21 "I think", so it would probably fit. The offset of the pulley is the only other unknown. It'd be worth it to buy one and try, if it can be returned easily.

If it fits then its a minor wiring plug change.

Several years ago I found a bosch internal regulator proposed for our cars. (I forget the seller)

Similar to this.

The red section is thicker because I got a 110Amp I think.

And, of course another question is WHY do you need more amps? Stereo stuff? Are you running out?

Sometimes the quest for "more" just for "more" isn't worth the effort.

Why not have your alternator rebuild locally.

Stereo unfortunately. Alternator not keeping up.

Haven’t been able to find anyone in Sydney who does it unfortunately.

 

Cheers guys.
