114-1131-006 Danfoss Char-Lynn 6000 Hydraulic Motor

Product Overview

The 114-1131-006, 114-1090-006, 114-1064-005 and 114-1080-006 belong to the Char-Lynn 6000 Series Geroler orbital hydraulic motor family. The current Danfoss PowerSource records identify 114-1090-006 and 114-1080-006 as 6000 Series 310-size motors with Geroler orbital gear sets and disc-valve architecture. 114-1131-006 is documented as a 195.8 cm³/rev bearingless 4-bolt motor.

The 6000 Series is a low-speed, high-torque hydraulic motor platform. Historical Char-Lynn engineering documentation specifies continuous pressure-differential ratings from 205 to 140 bar depending on displacement, intermittent ratings from 310 to 404 bar, and continuous torque ratings from 575 to 1685 Nm across the series.

For replacement applications, true interchangeability depends on more than displacement. Mounting flange, pilot diameter, bolt circle, output interface, hydraulic ports, case drain, check-valve or shuttle-valve configuration, sensor options and installation dimensions must all be verified.

Our replacement solution is developed around in-place interchangeability and 100% simulated working-condition testing, allowing each applicable configuration to be evaluated under defined hydraulic pressure, flow and rotational-speed conditions before shipment.

Control Type and Operating Principle

• Control Type: Fixed Displacement
• Hydraulic Valve System: Disc Valve
• Orbital Element: Geroler
• Speed Regulation: Primarily determined by hydraulic flow
• Torque Regulation: Primarily determined by pressure differential
• Direction Control: Reversal of A/B hydraulic flow changes shaft rotation
• Feedback Option: Hall-effect speed sensor on selected configurations such as 114-1090-006

The 6000 Series is fundamentally a hydraulic fixed-displacement motor platform rather than an electronically variable-displacement motor.

Key Technical Advantages

1. Geroler and Disc-Valve Architecture

The Geroler orbital mechanism combined with disc-valve distribution is the defining architecture of the Char-Lynn 6000 Series. The design targets low-speed, high-torque hydraulic transmission and controlled hydraulic distribution through the working chambers.

2. Wide Displacement Range

The 6000 Series is documented across multiple displacement classes from approximately 195 to 985 cm³/rev, allowing system designers to match motor displacement to required torque, speed and hydraulic flow.

3. Bearingless Drive Integration

Bearingless versions, including the configuration documented for 114-1131-006, are intended for systems where an external bearing arrangement supports the driven load. Proper coupling geometry and oil circulation therefore become essential parts of the mechanical design.

4. Predictable Flow-to-Speed Relationship

At 150 L/min, the 195-size motor is rated for up to 775 rpm continuous speed, while the 310-size motor is rated for up to 485 rpm. Increasing displacement reduces rotational speed per unit of hydraulic flow while increasing torque capability.

5. Configuration-Specific Functional Options

114-1090-006 includes a check valve and Hall-effect speed sensor, while 114-1080-006 is equipped with a hot-oil shuttle valve and no speed sensor. These differences are important during replacement because two motors with the same nominal size may not have the same circuit function.

6. Clearly Defined Pressure and Duty Limits

The 6000 Series documentation separates continuous, intermittent and peak pressure-differential conditions. For the 195 and 310 displacement classes, continuous pressure differential is 205 bar, while intermittent/peak limits are higher. These values must be evaluated against the actual machine duty cycle rather than treated as permanent operating targets.

7. Replacement-Focused Interface Matching

For replacement production, the critical engineering checks include:

• Displacement
• Shaft or bearingless interface
• Pilot diameter
• Bolt circle
• Mounting flange
• Port thread and orientation
• Case drain
• Check/shuttle valve arrangement
• Speed sensor configuration
• Overall envelope

This approach supports in-place interchangeability without assuming that nominal series identification alone guarantees mechanical compatibility.

Application Areas

Typical Char-Lynn 6000 Series application areas include:

• Construction Equipment
• Skid Steer Attachments
• Snow Removal Equipment
• Mowers and Turf Equipment
• Agricultural Sprayers
• Trenchers
• Wood Processing Equipment
• Mobile Hydraulic Drives
• Reel and Conveyor Drives
• Special-Purpose Machinery

Bearingless applications require particular attention to the external bearing and coupling arrangement because the motor itself is not intended to carry the same shaft-loading arrangement as a conventional shaft-and-bearing motor.

Expert Maintenance Tips

1. Confirm the Engineering Change Code

Do not assume -005 and -006 are identical service configurations. The Char-Lynn repair documentation explicitly distinguishes these versions and identifies component changes between them.

2. Protect the Shaft Seal During Service

Inspect the shaft, keyway and chamfered surfaces for burrs, nicks or sharp edges before installing the retainer and seals. A damaged shaft surface can quickly lead to external leakage.

3. Follow the Correct Timing Procedure

Geroler, valve drive, valve plate and valve timing determine hydraulic porting and output rotation. The 6000 Series repair procedure provides a specific timing sequence that should be followed during overhaul.

4. Use Controlled Bolt Tightening

The repair instructions specify a staged bolt-tightening procedure for the motor assembly. Controlled, sequential tightening is important for maintaining proper sealing and preventing localized mechanical distortion.

5. Maintain Hydraulic Cleanliness

The engineering documentation recommends premium anti-wear hydraulic fluid, a recommended cleanliness level of ISO 4406 20/18/13, and an operating temperature range of approximately -34°C to 82°C.

6. Break In a New or Rebuilt Motor

For best service life, the 6000 Series documentation recommends running the motor for approximately one hour at 30% of rated pressure before applying full load.

7. Control Case Pressure

Excessive case pressure can shorten seal and motor life. Where the application creates elevated return pressure, the case-pressure limitation and external drain requirements should be checked against the 6000 Series engineering data.

8. Engineer the Bearingless Coupling Correctly

A bearingless motor requires correct external load support, coupling geometry, lubrication and internal clearance. The Char-Lynn engineering documentation provides dedicated design requirements for the mating component and internal spline arrangement.
