Maybe someone has an answer for me. When changing conrod bearings for my 550d found out that Kolbenschmidt set for N57D30C fits all diesel engines for F series. However, the OEM part catalog says conrod bearings are interchangeable only between 1.6-2.5 diesels in F series and m50d. OEM was Schmiedmann if I'm correct. So got a bit confused why 3.0 and 3.5 diesels are not listed there.
Has someone used Kolbenschmidt set on 550d without any issues?
