W221 - engine 273 - коды на коленвале

[Bob Brown]

Столкнулся с проблемой - нужно поменять вкладыши на коленвале у 2010 S550, движок V8, 273.
У движка пробег 36 тыс км, выработка коленвала незначительная, поэтому вкладыши собираюсь поменять по указанным на коленвале, без замеров микрометром.
Вкладыши могут иметь разную толщину, в зависимости от выработки трущейся области коленвала. Толщина кодируется и маркируется на коленвале.

Проблема в том что я не знаю как прочитать маркировку на коленвале - какому номеру подшипника какой толщины вкладыши нужны.

Объясните, пож., если знакомы с маркировкой, как ее читать.

Hooray-hooray!!! I've got sizes!!! Tomorrow I'm going to order bearings!

The help was provided by Metric Motors, Inc.
They repair MB engines and were very nice to provide a detailed explanation.
I updated the image with crankshaft codes reading.
For info: I asked the same quesiton in 3 forums, visited dealership MB of Pompano, visited 2 local MB shops. Besides Mike fm Metric Motors nobody could answer the question.
Their complete answer is below:

Vasiliy,

The crankshaft bearing size codes are as follows.
Printed on the snout of the crank are the CAP bearing sizes.
#1 R-R-G-R-R #5 Special wider bearing
ORDER BEARING CODE SIZE
R = RED = CODE 56
G = YELLOW = CODE 54
B = BLUE = CODE 52
W = CODE 57
_ _ _ _ _ _ _

For the bearings that go on the block – there is a number stamped on the block next to each bearing cap.
1 =BLUE = CODE 52
2 = YELLOW = CODE 54
3 = RED = CODE 56

Hope that helps.

Regards,
Mike
