Its been since 2011 since I have been on this board. But my friend with the 1951 170S (with the 53 block) came to me with a connecting rod knock. I need to source some over sized bearings.  I find a lot of om676 bearings. 

Thanks

Here is example that leads me to believe the bearings may be the same:

I was afraid of that.  I was able to use cam bearing form the diesel engine sometime back and was hopping the same for the connecting rods.  Any good source for bearings for the 1953 M136 engine?

Here are the engine numbers:  136 925 3502682  cast: 1810110601  Cast: 14K53

Thanks for the help.

Dave you made a typo (OM 676). I'm sure you meant OM 636 and yes the bearings are the same as the M 136. Supply is difficult. Best is to find good NOS Glyco. There are good mains made by King bearings. I have seen defective rod bearings from the Chinese company TDC? or something like those initials. Good luck.
