This is a genuine BMW chain tensioner, part number 11 31 1 726 503. The number stamped on the part is 11311726503; BMW's catalog files it under the short number 1726503. You will find it on our Engine shelf, under CAMSHAFT. BMW has since replaced it with 1722654.

It fits the E36 sedan, coupe and convertible (320i, 325i and M3, 1992–1995), with the M50 or S50 engines.

BMW draws it on 2 diagrams, among them Timing - Timing Chain Lower P (11_1285) and Timing - Timing Chain Lower P (11_4858). It weighs about 208 g (0.5 lb).

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