Changing the connecting rod for your single cylinder engine. This is an essential step during the complete overhaul of an engine, aimed at ensuring optimal transmission of the movement between the piston and the crankshaft. This procedure generally involves checking the alignment, replacing the connecting rod rings, rectifying the contact surfaces and, if necessary, changing the shafts and bearings. Re-sizing helps to extend the life of the engine and improve its performance by reducing friction and mechanical play.
