130104000256A004 End Cap Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130104000256A004 end cap assembly is a core protective assembly for the hydraulic and transmission systems of engineering machinery. It combines sealing, dustproofing, pressure stabilization, and limiting functions, and is widely used in critical components such as motors, pump bodies, and transmission housings. It fits tightly to the mounting position, sealing the cavity ports to prevent hydraulic oil leakage and pressure loss, and blocking the intrusion of dust, mud, and sand. This effectively protects precision internal components such as bearings, valve cores, and gears, preventing equipment failures caused by wear and tear from impurities.
This product is made of high-strength alloy through integral casting, precision machining, and sealing treatment. Its dense structure is pressure- and impact-resistant, and not easily deformed. Combined with high-quality seals, it ensures a tight seal, making it suitable for harsh working conditions such as high-pressure operations, high-frequency vibration, mud and water erosion, and alternating temperature differences on construction sites. Old end caps are prone to deformation and seal aging and cracking, leading to oil leaks, pressure drops, dust ingress into the cavity, internal component wear, abnormal noises, and reduced equipment power, increasing maintenance costs. This product is of original factory standard specifications, with precise hole positions and high compatibility. It can replace old parts without damage, is suitable for equipment maintenance, major repairs, and bulk stocking, effectively improving equipment sealing and extending the service life of precision parts.
