This pump housing is the structural enclosure that supports the wet-clutch and gearbox hydraulic circuits. It houses the pump rotor and directs pressurized fluid to the clutch pack and lubrication galleries. A cracked or warped housing causes internal leakage, reducing clutch engagement pressure and leading to slipping or delayed engagement. As an original AGCO component, the casting is machined to the same bore tolerances and seal-surface finish as the assembly it replaces, so no shimming or line boring is required during installation. When reinstalling, use a new gasket and torque the mounting bolts to the specification for the host tractor.
