Product Overview

The Eaton Char-Lynn 103-1008-012 is a large-displacement Geroler orbital hydraulic motor engineered for heavy-duty low-speed high-torque applications. Featuring a rolling-element orbit set with constant-clearance rotor-stator matching and an optimized three-zone pressure distribution structure, this motor delivers smooth, chatter-free rotation and consistent torque output — exceeding 600 N·m at 1,500 PSI — with minimal internal leakage and pressure loss even under near-stall conditions. Its robust cast iron housing offers superior mechanical stability and shock resistance, allowing reliable performance in continuous-duty, frequent start-stop, and high back-pressure working environments. With a 22.7 CID displacement, standard 4-bolt SAE mounting dimensions, 1-inch keyed shaft, and 1/2-inch NPT porting, it provides outstanding interchangeability and low maintenance requirements, making it a highly reliable aftermarket replacement solution for forestry attachments, large-diameter augers, industrial shredders, heavy-duty sweepers, feed mixer wagons, and general industrial hydraulic drive systems demanding maximum torque from a single-stage orbital motor.

Key Features

• Excellent Universal Interchangeability Strictly manufactured in accordance with original Eaton 103-1008-012 size and performance standards, it matches perfectly with original equipment and equivalent mainstream orbital motors for direct plug-and-play replacement.

• Compact & Lightweight Design Adopts integrated miniaturized structural layout, which saves installation space effectively, making it ideal for compact hydraulic system assembly and equipment renovation.

• Smooth Low-Speed Operation Optimized gerotor tooth profile and precise flow distribution structure greatly reduce pressure pulsation, realizing ultra-stable and jitter-free low-speed rotation performance.

• High Energy Utilization Efficiency Polished internal flow channels minimize hydraulic resistance and fluid turbulence loss, effectively lowering system heat generation and improving overall working efficiency.

• Durable Wear-Resistant Structure Equipped with high-precision wear-resistant rotor and stator core components, resisting long-term cyclic friction and ensuring consistent power output for a long service life.

• Premium Leak-Proof Sealing System Adopts high-temperature and aging-resistant composite sealing kits, which effectively prevent internal pressure loss and external oil leakage, adapting to long-time continuous operation.

• Stable Variable-Load Adaptability Delivers steady and reliable torque output under frequent start-stop operation and fluctuating load conditions, with strong working condition adaptability.

• Rugged Industrial Construction High-rigidity cast iron housing resists vibration, minor impact and environmental erosion, ensuring stable operation in outdoor and dusty working sites.

• Low Maintenance Cost Features reliable overall structure and anti-failure performance, reducing daily maintenance frequency and lowering long-term equipment operating costs.

• Wide Application Coverage Perfectly suitable for agricultural machinery, sanitation vehicles, small construction equipment and general industrial hydraulic transmission devices.
