Fan Pump Replacement
This page is for the hydraulic fan-drive pump reference, rather than the excavator main work pump. When searching by 4633474, also compare the complete K3V63S code and the existing pump connections.
Match the shaft-end rotation, mounting, regulator and hose connections. The machine name alone does not establish the correct version for every serial number or regional build.
