Abstract

The process and apparatus avoid incorrect assembly and added expense caused by prior art alternating manual and equipment-reinforced assembly operations. Full automation is attained in that the component group is picked up by a robot and transferred to a press-fitting unit. Once the crankcase and the crankshaft, with the aid of rotary and adjusting devices, have been rotated into an assembly position for the piston and the connecting rod, the component group is introduced into a cylinder opening until the connecting rod contacts the crankshaft. The robot then picks up a connecting rod cap that has already been equipped with screws and screws it together with the connecting rod.
