Sundstrand Hydro-Transmission 64917003 233082 Hydraulic Motor

SUNDSTRAND HYDRO-TRANSMISSION 64917003 233082 Hydraulic Motor – New Unused Surplus

The Sundstrand Hydro-Transmission 64917003 / 233082 is a heavy duty and industrial grade axial piston hydraulic motor for high pressure closed circuit hydrostatic transmissions. Designed for demanding marine & mobile applications, this fixed/variable displacement motor provides continuous volumetric efficiency, strong torque output and precise bi-directional control.

Built on the classic heavy duty Series 20/23 design, introduced by Sundstrand Hydro-Transmission (now Danfoss), this unit features premium cast iron housing construction, precision ground swashplate surfaces and heavy duty cylinder blocks engineered for continuous operation under extreme pressure fluctuations. This unit is purchased straight from prime vessel stockpiles and strategic manufacturing reserves as a New, Unused Surplus assembly.

Technical Specifications 64917003 Hydraulic Motor

Key Features

1. High-Pressure Axial Piston Architecture. Optimized inline piston arrangement for continuous operation up to 3000 PSI (210 bar) and intermittent peak pressures up to 5000 PSI (350 bar).
2. Bi-Directional Operation: Symmetrical ports arrays for balanced torque development, and smooth manipulation of speed in clockwise (CW) and counter-clockwise (CCW) rotation.
3. High grade cast iron mechanical housing. Ruggedized monoblock cast structure to prevent internal structural distortion under maximum stresses, and maintain tight tolerances between the piston sleeves and slipper faces.
4. Precision Volumetric Efficiency: Optimized fluid power transmission throughout a wide variety of temperature environments, prevention of micro-cavitation and reduction of case leakage are all achieved by sophisticated valve plate profiling.
5. Flexible Splined Drive Shaft: Features a rugged industrial ANSI/SAE compliant splined shaft profile that’s designed to handle full torque loads without shearing or localized spine wear.

Compatible Models

• Marine Deck Machinery: Anchor handling winches, mooring winches, capstans, cargo cranes, and steering gear systems.
• Industrial & Mobile Heavy Machinery: Earthmoving machinery, heavy-duty crawler drives, concrete transit mixers, agricultural harvesters, and high-torque industrial conveyor drives.
