"WARNING" Possible engine damage by confusing connecting-rod bearing caps and connecting rods.

>The connecting-rod bearing caps must always remain allocated to the respective connecting rods and must never be interchanged.

Recommendation: After disassembly, immediately re-join the connecting-rod bearing cap and connecting rod or mark them on the sides with an electric scribing tool (e.g. with the cylinder designation). Never mark these parts with sharp objects such as prick punches or number embossing tools.
