Original BMW Connecting Rod Bearing Shell, Red 49.00 mm, M3 and Z3 M S54 (2001–2006)

For the S54 inline-six, BMW supplies this red connecting rod bearing shell in the 49.00 mm standard (0) size for the 2001–2006 E46 M3 and the 2001–2002 Z3 M Coupe and M Roadster. A rod bearing shell sits between the connecting rod and the crankshaft journal, carrying the load on a thin oil film so the crank turns freely. BMW names it the bearing shell, red, with the size marked 49,00MM(0), and each shell is sold individually. This number entered production in May 2003 and replaces 11-24-7-835-377. BMW rates the change as exchangeable retrospectively, so it also suits earlier S54 engines. The shell is made in Italy.

Original BMW Parts carry a 24-month parts warranty.

The red color and the 49.00 mm (0) designation separate this shell from other classes and sizes offered for the same engine, so match both to what your engine needs. BMW gives this part a limited storage life and directs that the expiry date on the parts label be observed before use. BMW's parts data shows it in the E46 M3 coupe and convertible, the M3 CSL, and the Z3 M3.2. It also cross-references to 11-24-7-834-826. Worn rod bearings commonly show up as a deep knock under load, low oil pressure, and metal flakes in the oil or on the drain plug.
