Product Overview

The Eaton Char-Lynn 103-1005-012 orbital hydraulic motor is a mid-displacement low-speed high-torque power unit tailored for medium-duty hydraulic machinery. It utilizes finely ground Geroler rotor-stator assemblies with rolling-element contact paired with balanced oil distribution to deliver steady, jitter-free rotation at 190 RPM with 333 N·m continuous torque and minimal pressure fluctuation. Its 11.4 CID compact cast iron integrated body owns outstanding structural rigidity and complete multi-layer sealing protection, resisting abrasion, oil leakage and interference from dusty, humid outdoor environments. Produced following strict original factory 4-bolt SAE dimension standards, this motor supports direct plug-and-play replacement without any mechanical alteration. With high Geroler transmission efficiency and low internal heat generation, it serves as a durable, cost-effective power solution for agricultural machines, municipal sanitation vehicles and medium-duty industrial transmission equipment.

Key Features

• 1:1 Original Dimensional Interchangeability Strictly produced per original Eaton 103-1005-012 drawing standards, matching flange, shaft and oil port sizes completely for direct replacement without machining.

• Ultra-Smooth Low-Speed Rotation Precision ground gerotor set with balanced flow distribution suppresses pressure pulsation, avoiding crawling and shaking under low-speed working conditions.

• Mini Compact Integrated Layout Lightweight one-piece cast iron housing takes up less installation space, ideal for small-sized agricultural and sanitation hydraulic equipment.

• High Transmission Efficiency & Low Heat Rise Polished internal flow passages cut fluid resistance and turbulence loss, less heat buildup to lighten system cooling load.

• Long-Lasting Wear-Resistant Core Parts Rotor and stator undergo precision surface treatment to resist long-time cyclic friction and extend whole motor service life.

• All-Weather Composite Sealing System Oil-proof, high-temperature resistant and anti-aging seal kits stop internal pressure drop and external oil leakage during continuous operation.

• Stable Output Under Variable Loads Maintains consistent torque when facing frequent start-stop and fluctuating loads, with excellent anti-fatigue performance.

• Strong Anti-Dust & Anti-Vibration Housing High-rigidity cast iron shell withstands field vibration, dust and humidity, reliable for outdoor harsh working environments.

• Low Maintenance & Low Operation Cost Simplified internal mechanical structure reduces fault probability, cutting later maintenance frequency and downtime loss.

• Wide Range of Application Scenarios Perfectly matched for small farm machinery, municipal cleaning vehicles, light conveyors and other light-duty hydraulic drive devices.
