This series of high-torque hydraulic motors is a low-speed, high-torque drive solution specially developed for Earthmoving Attachments. As a direct replacement for the Charlynn 104, 105, 106 series and the same models of other international brands (such as Eaton 2000 series, Danfoss OMS series), this motor adopts advanced Disc Valve technology and Geroler gear set design, providing excellent starting torque and stable low-speed performance in a compact volume.

Whether used for augers, sweeper brushes, mowers or conveyor belt drives, this series of motors can provide reliable, efficient and long-life power output in harsh earthmoving conditions, helping your equipment maintain optimal working conditions under various ground conditions.

1. Disc-type valve distribution technology – Excellent low-speed and starting performance
This series of motors adopts an advanced disc-type valve distribution structure, which has significant advantages over traditional valve distribution methods:
• Automatic wear compensation: The valve plate can automatically compensate for wear during operation, maintaining high volumetric efficiency for a long time.
• Low starting pressure: Optimized flow channel design enables the starting torque to reach more than 92% of the theoretical torque, easily overcoming the starting resistance under heavy loads.
• Excellent low-speed stability: It can run stably even at extremely low speeds (<10 rpm) without crawling, achieving precise control.

2. Geroler gear set – High efficiency and durability
The roller-type cycloidal gear set (Geroler) is adopted, which has more advantages compared with the traditional Gerotor design:
• Rolling friction: Rollers replace sliding friction, increasing mechanical efficiency by 5-8%.
• Better sealing performance: The line contact between rollers and gear ring results in better sealing effect and higher volumetric efficiency.
• Longer service life: Reduced wear, with a B10 life of more than 10,000 hours.

3. Strong load-carrying capacity
• Heavy-duty bearing system: Tapered roller bearings are used at the output end, which can bear high radial and axial loads.
• Impact-resistant design: Key components are strengthened to withstand impact loads in earthwork operations.

4. Fully interchangeable design
• Dimensional zero error: Manufactured strictly in accordance with the original factory drawings, the positions of the mounting flange, shaft extension, and oil port are completely consistent with the Charlynn 104/105/106 series.
• Plug-and-play: It can directly replace the damaged original motor without modifying any pipelines or brackets.
• International compatibility: It is also compatible with Eaton 2000 series, Danfoss OMS series and other models with the same displacement.
