Collar nut — a genuine BMW part, number 23 21 7 543 319. The number stamped on the part is 23217543319; BMW's catalog files it under the short number 7543319. You will find it on our Transmission shelf, under Transmission shafts. It supersedes the older number 1224822, so a part carrying that number is the same part.

It fits the E36 sedan, coupe, convertible and touring (325i, 328i and M3, 1992–1999), with the M50, M52, S50 or S52 engines — and the European-market versions. It also fits every E46 body style (325i, 328i and 330i, 1999–2006), with the M52 or M54 engines — and the European-market versions.

BMW draws it on 5 diagrams, among them S5D...Z drive shaft/output shaft (23_0126) and GS5S31BZ(SMG) Drive-/Output shaft (23_0938). It weighs about 36 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.
