This seal kit contains the gaskets needed to reseal the valve plate assembly in the hydraulic system of the host tractor. The valve plate directs pressurized oil to the implement circuits; worn or hardened seals at this interface allow external leaks and internal cross-port leakage, which reduces system pressure and causes sluggish or erratic implement response. The kit includes the specific gaskets that match the sealing surfaces of the original valve plate, preserving the clamping force and port isolation the assembly was designed for. On reinstallation, clean the mating surfaces thoroughly and torque the valve plate retaining bolts to the manufacturer's specification.
