Caterpillar 9J5070 Hydraulic Pump

The Caterpillar 9J5070 (also cataloged as 9J-5070) Hydraulic Pump is a complete hydraulic pump group (Pump G) designed for Cat wheel loaders, including the 980 series. This unit is configured around a Sperry Vickers F10 3525VC 38A hydraulic pump, forming the power-path component that drives the loader’s hydraulic functions. In Caterpillar parts literature, 9J5070 is identified specifically as a Pump G assembly and is listed for machines including the 950 and 980 series, making it a common replacement part within the Cat hydraulic system. The assembly’s Sperry Vickers vane pump provides the hydraulic flow essential for operating the loader’s lift and attachments, and the 9J5070 designation helps service technicians locate compatible parts and mating components within Cat’s service ecosystem. Exact fitment depends on the machine’s configuration, so verifying with a Caterpillar dealer or parts catalog using the machine serial number ensures proper mounting, port layout, and any required adapters or companion kits.
