340-9400: 144.97mm Diameter Piston Ring

Description: A Piston Ring is a circular metal ring with a beveled edge that is located on the top of the piston, which is in charge of sealing the combustion chamber and preventing gas leakage into the crankcase. It is often made from materials of high strength and has been designed to endure pressure and temperature changes, and controls the oil flow around the piston. Attributes: • Nitriding surface treatment is used on the piston ring to increase wear resistance. • Specifically made to assure correct fit by matching the piston and cylinder dimensions. Application: A Piston Ring act as a seal between the piston and the cylinder wall, mostly used in Cat 2806, 2806F, C140, 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, 735, 740, 740C, 745, 745C and 760 Articulated Trucks, 745 and 745C Oem Applications, 770G, 772, 772G, 777, 777F, 777G, AD45 and AD45B Trucks, 834, 834K, 854 and 854K Wheel Type Tractors, 834, 988, 988H, 988K, 992, 992K, 993, 993K and R3200 Wheel Loaders, 836 and 836K Compactors, C15 Engine-General Platform, C18 Engine-General Platform (C18), C18 Power Systems, C18, C32, C6.6, XQ1140, XQ570 and XQP550 Generator Sets, C27 & C32 Engine-General Platform, D11, D11T, D9 and D9T Track Type Tractors, MD6200, MD6310 and MD6420C Drills, MH3295 Material Handlers, PM1125, PM1138, PM6, PM620, PM622, PM8, PM820, PM822, PM825, PM922, PM925, PM938, RM600, and RM800 Paving Equipment.
