been done the gripping device 8 can be removed and a piston insertion sleeve which is not shown here but which is known in the state of the art can be centered at the upper cylinder liner fitting entry after the piston 1 has been released from the gripping device 8 the connecting rod 3 together with the piston 1 can be moved downwardly by means of the mounting bar assembly 10 and the open connecting rod eye 19 can be fitted on to the crankshaft 11 then the connecting rod yoke which is not shown here but which is known in the state of the art with the connecting rod bearing shell fitted therein can be screwed to the connecting rod 3 with its initial tightening torque after removal of the piston insertion sleeve which is not shown here further operation is effected as is known in the state of the art with a device for clamping down the cylinder liner 6 that clamping down device can then be removed after hardening of the sealing agent and after a sealing integrity check the further steps for fitting the cylinder head at the cylinder head bolts 9 are known in the state of the art in the removal operation the procedure involved in accordance with the invention can be as follows firstly the connecting rod yoke which is not shown in the drawings with the bearing shell 15 is unscrewed from the connecting rod eye 19 and removed the fixing lugs 14.
