Hi,

I am in the process of rebuilding a spare engine and I've got troubles with my brand new OEM Rod bearings.

My main bearings have a number printed on each of them regarding their size.
And engraved numbers which do nor correltate to the size.
OEM main bearings upper (imprint on block 2-3-2-2-2)
STD 0 1052B019
STD 1 1052B020
STD 2 1052B021
STD 3 1052B022

My rod bearings are unfortunately a totally different story.
I have ordered according to my imprint on the crank (1-1-1-2)
STD 1 1115A291
STD 2 1115A292
STD 3 1115A293

So I end up with two pieces of STD 2 and 6 pieces of STD 1 but none of them has those black identification numbers printed. They only have numbers & letters engraved into them which do not help me identifying them.

The two rod bearings in the picture are both size 2, dont have a number printed on it and have different engraved numbers & letters.

Beside that also my 6 pieces of size 1 have different numbers & letters.

I am somehow worried that they are not the correct sizes. Does those engraved numbers tell anything?
