( Brand: Lycoming ), ( Manufacturer Part Number: 62821 ), ( Part Type: Piston )
The Lycoming 62821 Pistons are high-performance components designed specifically for Lycoming engines, offering exceptional reliability and durability. These pistons are constructed from forged 4140 alloy steel, which ensures they can withstand the extreme pressures and temperatures found in an engine's combustion chamber.
Each piston features a full-floating wrist pin with a low-tension design, reducing the chance of pin-bearing failure. The pin is further protected by a double-lip sealing ring, which helps to prevent oil leakage and ensure optimum engine performance.
The piston skirt is fully grooved for superior ring sealing, while the crown is optimized for combustion chamber shape and compression ratio. This design ensures efficient gas flow, reducing heat transfer and providing improved engine efficiency.
The piston rings are made of high-quality, chrome-silicon alloy, providing excellent wear resistance and sealing properties. The top ring is a two-piece design, which allows for easy installation and removal without the need for ring expanders.
The piston pin bore is precision-honed for a perfect fit, ensuring a smooth operation and reducing the chance of pin movement or damage. The piston also features a heat-treated, chrome-plated skid plate, which protects the piston from scuffing during engine operation.
In summary, the Lycoming 62821 Pistons are a high-quality, reliable solution for Lycoming engine owners. Their superior construction, design, and materials ensure efficient operation, reduced wear, and extended engine life.
