This clutch pump supplies hydraulic pressure to disengage the clutch system in the host tractor. It is mounted on the engine or gearbox housing and draws fluid from the reservoir to actuate the clutch release mechanism. A failing pump produces a slow or incomplete clutch disengagement, often accompanied by a whining noise from the hydraulic circuit. This Valeo unit matches the original assembly's displacement and mounting flange geometry, so no adapter brackets or line modifications are needed. On installation, bleed the hydraulic circuit according to the service manual to remove trapped air.
