Engine piston / Ø 85 mm / STD / Shibaura LEM853 / Shibaura SD2640D

Engine piston (rings 6-26-100-58) with an outer diameter of 85 mm and a total height of 91 mm for Shibaura tractors of the Shibaura SD2640D series with Shibaura LEM853 engines and others. The engine piston is a moving element responsible for converting gas and energy generated during combustion to the crankshaft, i.e. further into engine power. The piston is connected to the crankshaft by an element called a connecting rod with pin connections. At the top of the piston there are ring channels for mounting the piston rings, in the middle there is a hub for connecting to the connecting rod. At the top there is a so-called bottom, which, depending on the type of engine, may have a different shape. Due to work in very difficult conditions, engine pistons are most often made of aluminum and silicon alloys.
