This is the BorgWarner 53279886533, a new K27 turbocharger, not a rebuild, for the Mercedes-Benz OM502LA 16L V8 diesel. It is a BorgWarner (KKK) K27, model K27-3465MXEAA/18.20, and the tag may show the number as 5327 988 6533. It replaces Mercedes-Benz A0090961799 and A0090968699 and the older KKK numbers 5327 970 6533 and 5327 988 6522. The OM502LA is the V8 used in Mercedes-Benz Actros trucks and in Claas machines, and more than one K27 was built for it, so confirm the number on your old turbo before you order.

Low boost, black smoke under load, oil in the charge pipes, a whistle or siren sound, or shaft play you can feel at the compressor wheel are the usual reasons to change a turbo. Find out why the old one failed first. Dirty or late oil, a restricted oil feed or drain line and dust getting past the air filter will take out a new turbo the same way.
