-- View BMW DiagramSee this part on the official exploded view→Alternator — a genuine BMW part, number 12 31 1 277 239. The number stamped on the part is 12311277239; BMW's catalog files it under the short number 1277239. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 1271663, so a part carrying that number is the same part.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 7 diagrams, among them Alternatormounting Parts (12_0206) and Alternatormounting Parts (12_0207). It weighs about 6.0 kg (13 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
