This clutch pump supplies hydraulic pressure to disengage the clutch in the drivetrain of the host tractor. It is driven by the engine and feeds the clutch-actuation circuit, enabling the operator to shift gears or engage the PTO. A failing pump produces a slow or incomplete clutch release, making gear engagement difficult. This component is manufactured to the original piston diameter and housing geometry, so it maintains the correct displacement and pressure output without requiring shims or adapter plates. When installing, ensure the drive coupling aligns properly and the mounting bolts are torqued to specification.
