DESCRIPTION
An engine piston kit, identified by part number 5473379, is a set of components that make up the internal combustion engine's piston. The kit includes a piston head, wrist pin, and retaining clips. The piston head is the main component that moves up and down in the cylinder bore to transfer energy from the fuel combustion to the crankshaft. It is typically made of aluminum alloy or steel and must be machined to precise tolerances for optimal performance. The wrist pin connects the piston head to the connecting rod and allows it to pivot as it moves up and down in the cylinder bore. Retaining clips secure the wrist pin in place on both ends. Together, these components are crucial for proper engine function and must be carefully maintained or replaced as necessary to ensure optimal performance and reliability over time.
