AL151513 is a gear-plunger dual-module hydraulic pump specifically engineered for John Deere 6300, 6405, 6500, 6600, and 6605 series tractors. As an OEM-specific replacement part, it precisely matches the hydraulic system interfaces, power parameters, and installation layouts of these models. Its core purpose is to resolve issues such as pump wear and power degradation in older models, rapidly restoring hydraulic system performance without requiring pipeline modifications. It serves as the preferred replacement part for John Deere 6000 Series tractors at agricultural machinery repair shops and large-scale farming operations. Strictly adhering to John Deere 6000 Series tractor OEM manufacturing standards, the pump body mounting holes and shaft diameter dimensions perfectly match the original hydraulic pump. The inlet and outlet port thread specifications align with the machine's piping interfaces, allowing direct integration into the existing hydraulic system during installation. This eliminates power loss or installation rework caused by compatibility deviations, significantly reducing replacement time.
