Eaton Hydraulic Motor W/Hprv

Eaton Hydraulic Motor W/Hprv

This is a remanufactured Eaton 4633-010, a heavy-duty hydrostatic piston motor used as a drum drive motor on concrete mixers. It is specifically cited as a common component on Terex Advance front discharge mixers. The motor's fixed displacement design and integrated high-pressure relief valve (HPRV) ensure consistent and safe drum speed during transit and operation. A replacement would be necessary due to hydraulic failure, leakage, or wear and tear, which would prevent the mixer drum from rotating correctly. This model features a 21-tooth splined shaft and robust cast iron construction suitable for the demanding environment of concrete mixing.
