AllDescription of Change: New seals and backup rings are available for hydraulic cylinders that are resistant to dieseling and explosive decompression. The new seals and backup rings are more resistant to damage.The new expander rings reduce the area of the seal that is exposed to hydraulic oil. This will help to prevent air from propagating into the expander ring. The new backup rings support the seal under high system pressures. This will prevent damage to the seal from extrusion. Dieseling occurs when air that is trapped under the seal for the piston is rapidly compressed. The air and the oil vapors that are in the air then ignite. Explosive decompression occurs when air or other gases that have propagated into the rubber expander ring are rapidly expanded. This occurs when there is a sudden drop in oil pressure in the cylinder.These problems are generally found in large hydraulic cylinders. These problems damage the seal and the expander ring. Removing all of the air that is in the hydraulic system can help to reduce these problems. Some air will still be generated during normal operation of the machine. Adaptable To: The new seals and backup rings are available for a wide variety of large hydraulic cylinders. These cylinders are typically found on large wheel loaders, front shovels, and large track-type tractors. The new seals and backup rings are based on the diameter of the cylinder bore. Refer to the following chart in order to determine the correct part numbers for the hydraulic cylinder.
