Compact alternator — a genuine BMW part, number 12 31 1 738 351. The number stamped on the part is 12311738351; BMW's catalog files it under the short number 1738351. You will find it on our Electrical shelf, under Alternator with motor and mounting. BMW has since replaced it with 1744563.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 2 diagrams, among them Alternator Parts 140a (12_0474) and Alternator Parts 140a (12_0477). It weighs about 7.8 kg (17 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
