Need tech info M103 engine
I need to know if I need oversized main and rod bearings. I cannot find this information anywhere!!! I just spend $80 on an official mercedes benz service manual and it wasn't in there. Can anyone help me out? What is the standard journal diameter and when does it require oversizing? I have already measured my crank...i just need data to compair it too. Thankyou!
|
Standard size main crank journal is 57.950 to 57.965mm.
Std size rod journal is 47.935 to 47.955mm. There are 4 repair sizes for either, mains or rods in .025mm increments. .06mm clearance on the mains would be max. .04mm clearance on the rods would be max. |
Thankyou Pat, I appreciate it!
|
I have figured out that I can stay standard on both my main and rod bearings...can I just assume that my thrust bearings are standard too? If not, can you give me those clearances too?
|
The standard size of the thrust bearings is 2.15mm & the clearance(endplay) is 0.10 to 0.20 mm.
|
I don't suppose you could tell me the stock thickness of the head gasket...could you?
