Engine piston / Ø 72 mm / STD / Kubota D902

Engine piston (rings 1G962-21112, head gasket 1G962-03313-D902) with an outer diameter of 72 mm and an overall height of 56.30 mm for Kubota tractors and other machines of the Kubota BX25, Kubota BX2350D, Kubota KX018, Kubota KX41, Kubota KX41-3, Kubota RTV900, Kubota U17, Kubota ZD323 series with Kubota D902 engines. The engine piston is a moving element responsible for converting the gas and energy produced during combustion into the crankshaft, and thus into engine power. The piston is connected to the crankshaft by a component called 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 connection to the connecting rod. At the top is the so-called the bottom, which may have a different shape depending on the engine type. Due to operating in very harsh conditions, engine pistons are most often made of aluminum and silicon alloys.
