This is a genuine BMW mechanical belt tensioner, part number 11 28 1 748 832. The number stamped on the part is 11281748832; BMW's catalog files it under the short number 1748832. You will find it on our Engine shelf, under Other Engine parts. It supersedes the older number 1735899, so a part carrying that number is the same part. BMW has since replaced it with 1427252.

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

BMW draws it on 2 diagrams, among them Belt Drive Water Pump/Alternator (11_1447) and Belt Drive Water Pump/Alternator (11_6061). BMW lists the quantity used as “as required”. It weighs about 934 g (2.1 lb).

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