Engine piston / Ø 80 mm / STD / Shibaura LEK802 / Shibaura SD1540

Engine piston (rings 6-26-100-56) with an outer diameter of 80 mm and an overall height of 95 mm for Shibaura tractors of the Shibaura SD1540 series with Shibaura LEK802 engines and others. The engine piston is a moving part responsible for converting gas and combustion energy into the crankshaft, and thus into engine power. The piston is connected to the crankshaft by a connecting rod with pin connections. At the top of the piston are annular channels for mounting the piston rings, and in the center is a hub for connecting to the connecting rod. At the top is the so-called crown, which can have different shapes depending on the engine type. Due to the very harsh operating conditions, engine pistons are most often made of aluminum and silicon alloys.
