introduced into the large eye for example by milling or turning depending upon the kind of bearing g then the large connecting rod eye is notched for example with an fk laser which is driven through the eye at 45 u00b0 with a laser power of approx 7 kw to produce a notch of approx 2 mm in width and 0 5 mm in depth centrally in the eye the notch may alternatively be introduced by a broach or by eroding the connecting rod eye is cracked by a breaking device with a breaking force of approx 100 kn the connecting rod bearing cap is removed and the rupture area cleaned for example by compressed air the connecting rod bearing cap is then reassembled and the cap bolts tightened with an appropriate torque after that the large connecting rod eye is plasma coated and a bearing bushing is pressed into the small eye the large eye is chamfered on both sides the connecting rod cheeks are finish ground and the large and small eyes are fine bored or fine spindled this is followed by thorough cleaning washing and measuring and classification of the connecting rod the connecting rod is disassembled on the assembly line and assembled on the crankshaft of an internal combustion engine cracking of the plasma layer in particular by loosening of the connecting rod cap bolts may be effected directly on the assembly.
