This valve plate seal kit provides the gaskets and seals that prevent hydraulic fluid leakage between the valve plate and the manifold body in the host tractor's hydraulic system. The kit contains all the sealing elements required to restore the original sealing pressure at each port and passage within the valve plate assembly. When the original seals harden or develop leaks, the system loses pressure at the control valves, causing sluggish or incomplete actuator response. The seals are manufactured to match the original groove geometry and material hardness, so the valve plate retains its factory clamping force without over-torquing the mounting bolts. On reinstallation, clean the sealing faces thoroughly and torque the valve plate bolts to the specified value.
