This is a genuine BMW ring, part number 12 31 1 735 305. The number stamped on the part is 12311735305; BMW's catalog files it under the short number 1735305. You will find it on our Electrical shelf, under Alternator with motor and mounting.

It fits the E36 sedan and coupe (320i and 325i, 1992–1995), with the M50 engine.

BMW draws it on 24 diagrams, among them Alternator Parts 140a (12_0251) and Alternator Parts 140a (12_0253). It weighs about 6 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.
