ACR Alternator

Post by lindenengineering »

Guys
I have just stumbled across an identical NEW Bosch ACR 40A 24v unit. Exactly the same dimensionally as the original, except for the fixing nut thread diameter.
I am getting some original fan pulley cap nuts bored out and threaded to accept the new unit and put it on trial.
Stay tuned
Dennis

Nice find Dennis, I am guessing if these alternators pass muster,we will have a lower cost alternator source???

Well these units fit exactly where the old one used to dwell.

Difference--the thread and shank diameter of 2mm larger so the pulley sheave fixing nut has to be opened up. I have two undergoing "surgery" by a machine shop in town. One genuine Steyr spec nut and one from a Super Beetle made in Brazil!

The "in chassis mod" will be to dump the reg box and wire the machine with a feed directly from the red indicator light to exite the unit through the cut off relay.
Stay tuned I am hoping to have this up 'n running by next week!

The parts for the old unit are getting tight so this find is important.
The one I have is made in Turkey by Bosch --hope it turns out NOT to be a "turkey" :twisted:

Bloody rotten timing....since my pinz was down at your place just a few months back needing a new alternator.

I'm interested in watching this - I've been pondering what it would take to put a higher output alternator on the beast, since I think the stocker is 35A? Can almost never have too much juice available....

thanks for the investigation, will be watching for results!
