8T4772 2976848-G 1137482/SI-G Hydraulic Cylinder Excavator Lift Tift Steering Seal Kit

For heavy machinery such as an excavator or wheel loader, the hydraulic cylinder seal kit is critical for lift, tilt, and steering functions. The kit containing 8T4772 is engineered to match original equipment specifications. When you need a reliable seal solution for your excavator’s hydraulic system, 8T4772 ensures leak-free performance in both lift and tilt cylinders. This part number 8T4772 also integrates seamlessly with loader hydraulic cylinders, preventing contamination and pressure loss. Operators seeking a steering seal kit for their excavator should verify 8T4772 against the machine’s serial number.

Another essential reference is 2976848-G, which frequently appears alongside 8T4772 in seal kit assemblies for excavator loaders. The 2976848-G designation often corresponds to the tilt cylinder seal arrangement, while 8T4772 may cover lift or steering applications. For a complete hydraulic cylinder rebuild on an excavator, both 2976848-G and 8T4772 might be required depending on cylinder bore size. Many aftermarket kits combine 2976848-G with 8T4772 to provide full coverage for loader lift and tilt functions.

The third critical identifier is 1137482/SI-G, which is specifically designed for steering cylinder applications in excavators and loaders. Unlike 8T4772 which focuses on lift/tilt cylinders, 1137482/SI-G addresses the unique sealing needs of steering hydraulic circuits. However, 8T4772 remains the primary cross-reference for loader hydraulic cylinder seal kits, while 1137482/SI-G serves as a supplementary option for steering systems. When ordering, always confirm whether your excavator requires 8T4772 for lift/tilt or 1137482/SI-G for steering seals.
