This is a genuine BMW lock Ring, part number 23 31 1 666 278. The number stamped on the part is 23311666278; BMW's catalog files it under the short number 1666278. You will find it on our Transmission shelf, under Inner gearshift parts.

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

BMW draws it on 10 diagrams, among them Getrag 242 Inner Gear Shifting Parts (23_0325) and Getrag 242 Inner Gear Shifting Parts (23_0326). It weighs about 1 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.
