This metal plate is a mounting or interface component within the hydraulic system of a loader. It serves as a structural attachment point, securing a hydraulic component — such as a valve block, manifold, or cylinder bracket — to the loader frame or chassis. The plate maintains the correct alignment and spacing between the hydraulic assembly and the machine structure, preventing stress or misalignment in the hydraulic lines. A warped or damaged plate can cause mounting bolts to loosen over time, leading to fluid leaks or component movement under load. The original plate is machined to match the bolt-hole pattern and surface flatness of the factory assembly, so no shimming or modification is required during replacement.
