The big end bearing cap of an internal combustion engine connecting rod is connected to the remainder of the connecting rod by bolts which locate the big end bearing shells both angularly and axially of the bearing. The machining of the bearing surface is carried out with the cap bolted to the remainder by either the bolts which are to form part of the completed connecting rod or by slave bolts which may be repeatedly used. In the former case, parts of the bolts are cut away as the envelope of the bearing cylinder and those of the bolt holes overlap and in the final assembly of the bearing these bolts are turned through 180 DEG so that their cut-away portions face away from the bearing surface.
