This is a genuine BMW grooved ball bearing, part number 12 31 1 714 521. The number stamped on the part is 12311714521; BMW's catalog files it under the short number 1714521. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older numbers 1276219 and 9057489, so a part carrying any of them 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 28 diagrams, among them Generator, individual parts (12_0184) and Generator, individual parts (12_0185). It weighs about 30 g (under 0.1 lb).

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