Engine piston / Ø 68 mm / Kubota B5100 / B5200 / B7100 / Kubota D750 / Z500

Engine piston (rings 6-26-100-63, 15271-21050, 16106801-00, S.67709) with an outer diameter of 68 mm and an overall height of 65.50 mm for Kubota tractors of the Kubota B5100, Kubota B5200, and Kubota B7100 series with Kubota D750, Kubota Z500 , and other engines. The engine piston is a moving element responsible for converting gas and the energy generated during combustion 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 seating the piston rings, and inside is a hub for connecting to the connecting rod. At the top is the so-called crown, which may have a different shape depending on the engine type. Due to their operation in very difficult conditions, engine pistons are most often made of aluminum and silicon alloys.
