112-1068-006 Eaton 6000 Series Hydraulic Motor

Product Overview

The 112-1068-006, along with its series counterparts (112-1138-006, 112-1066-006), is a high-pressure, low-speed high-torque (LSHT) disc valve hydraulic motor engineered for heavy-duty applications. Designed as a premium drop-in equivalent for the Eaton Char-Lynn 6000 Series, this motor is manufactured to the highest fluid power standards. Every single unit undergoes 100% rigorous simulated operational testing prior to shipment, guaranteeing absolute true interchangeability in mounting flanges, shaft dimensions, and port configurations. Consistently delivering robust mechanical efficiency and smooth power output under extreme pressure drops, this motor is the ultimate driving force for demanding mobile and industrial machinery.

Key Technical Advantages

• 100% True Interchangeability: Meticulously engineered to match the Eaton 6000 series perfectly. The external dimensions, mounting bolt patterns, and hydraulic ports are identical, allowing for seamless plug-and-play installation during equipment upgrades or field repairs without modifying existing hydraulic circuits.

• Advanced Geroler Gear Set: Features a precision-ground Geroler star and stator profile utilizing rolling cylinders. This design converts sliding friction into rolling friction, enabling exceptional starting torque and maximizing volumetric efficiency even under sustained high-pressure operation.

• Dynamic Clearance Compensation Disc Valve: The separate valve drive and hydrostatically balanced disc valve automatically compensate for wear and thermal expansion. This ensures that the motor maintains peak volumetric efficiency and minimal internal leakage throughout its entire operational lifecycle.

• Heavy-Duty Tapered Roller Bearings: The robust output shaft assembly incorporates high-capacity tapered roller bearings capable of absorbing massive radial and axial loads. This eliminates the need for external outboard bearings in direct-drive applications such as wheel drives or heavy earth augers.

Application Areas

• Construction Machinery: Wheel and track drives for skid steer loaders, swing drives for excavators.

• Specialty Vehicles: Sweeper brush drives, traction drives for Aerial Work Platforms (AWP).

• Mining & Agricultural Equipment: Heavy-duty earth augers, trenchers, and severe-duty forestry processing heads.

Expert Maintenance Tips

• Optimal Break-in Period: During the first hour of operating a newly installed 112-1068-006 motor, limit the operating pressure to 30% of its maximum continuous rating. Cycle the motor in both directions under light loads to establish a proper hydrodynamic lubricating oil film on internal friction surfaces.

• Strict Case Drain Utilization: While the 6000 series architecture is designed to handle elevated back pressures, it is highly recommended to route a dedicated case drain line directly to the reservoir. This provides critical internal cooling and ensures housing pressure remains below 20 bar, significantly extending the life of the high-pressure shaft seal.

• Fluid Cleanliness Standard: Precision disc valve motors are highly sensitive to particulate contamination. Maintain hydraulic fluid cleanliness to a minimum standard of ISO 4406 20/18/13, and ensure 10-micron return line filters are serviced at regular intervals.
