01 View BMW DiagramSee this part on the official exploded view→Generator (exchange unit) — a genuine BMW part, number 12 31 1 731 103. The number stamped on the part is 12311731103; BMW's catalog files it under the short number 1731103. BMW's catalog calls it “EXCH generator”. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 1466340, 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 5 diagrams, among them Additional Alternator/Mounting Parts (12_0385) and Additional Alternator/Single Parts (12_0387). It weighs about 3.5 kg (7.7 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
