W221 - engine 273 - reading crankshaft codes
I have to change crankshaft bearings on 2010 S550, engine 273.
The engine has 24k miles and I'm planning to use the same bearing color codes as marked on crankshaft.
The problem is: I don't know how to read codes on crankshaft.
If somebody knows, could you, please, explain how to read - where on crankshaft each bearing number is coded?
Is it coded as:
1 3 5
2 4
or
1 2 3
4 5
?

Update:
____________________________________
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

2007 S550
Help
My car won't start. I Just started having this problem about 2 weeks ago. It will turn, but won't catch or start then stop immediately. . Finally I was stranded at home so with a little bit of advice I change the crankshaft sensor and the vehicle still did not start so I was wondering if anybody had any ideas it is a 2007 Mercedes Benz S550. Please any help would be great im trying not to have it towed to the dealer because I don't have the money to spend at this time. You can respond here or email me directly at familyaffairbarbershop@gmail.com thanks!
