340-3639: 144.97mm Inside Diameter Piston Oil Control Ring

Description: The piston oil control ring is a vital component of an internal combustion engine's piston assembly. It regulates the flow of oil between the piston and the cylinder wall. The control ring is made of high-quality materials, that are resistant to wear and corrosion. Its design consists of multiple narrow bands or segments that encircle the piston, creating a controlled gap between the ring and the cylinder wall. This gap allows the oil to be distributed and scraped away effectively, preventing excessive oil consumption and maintaining proper lubrication within the engine. The control ring's precise fit and tension against the cylinder wall ensure optimal sealing and prevent oil leakage into the combustion chamber. By managing the oil flow and preventing oil from reaching areas where it could interfere with the combustion process. Attributes: • Withstand high temperatures and pressures • Preventing oil leakage into the combustion chamber. Applications: The piston oil control ring is used for efficient oil control and lubrication within the engine, contributing to its smooth operation and longevity. It is majorly used in Cat 2806, 2806F, C140, C140-16, C18, C27, C32, and C32B Engine (Piston), 390E, 390F, 395, 6015, 6015B, 6020B, and 6040 Excavators, 631, 631K, 637, 637K, 651, 651E, 657, 657E and 657G Wheel Tractor Scrapers, 740, 740C, 745, 745C and 760 Articulated Truck, 745, 745C and 777F 770G, 772, 772G, 777, 777B, 777C, 777D, 777E, 777F, 777G, AD45 and AD45B Truck, 834, 834K, 854 and 854K Wheel Type Tractors
