109-1118-006 Danfoss Char-Lynn 4000 Motor

Product Overview

The 109-1118-006 and 109-1319-006 are Danfoss / Char-Lynn 4000 Series low-speed, high-torque orbital hydraulic motors.

Danfoss describes the 4000 Series as a larger-frame development of the 2000 Series architecture, designed for higher torque and flow. The current Danfoss product category specifies up to 95 L/min continuous flow, 151 L/min intermittent flow, 207 bar continuous pressure and 310 bar intermittent pressure at the series level. Exact performance remains configuration-dependent.

The exact Danfoss PowerSource configuration for 109-1118-006 specifies:

• 4000 Series
• Disc valve with valve drive
• Geroler orbital gearwheel set
• 246.3 cm³/rev
• 4-bolt square SAE B mounting
• 1-1/4-inch 14T splined shaft
• 1-1/16-12 SAE O-ring side ports
• 7/16-20 SAE O-ring case drain

Final procurement should be verified against the original nameplate and historical OEM documentation.

4000 Series Platform Limits

Danfoss’s current 4000 Series documentation gives the family-level envelope:

• Maximum continuous flow: 95 L/min / 25 GPM

Key Technical Advantages

Disc-Valve Geroler Architecture

The Char-Lynn 4000 Series uses a disc valve with valve drive and Geroler orbital gearwheel set, providing the hydraulic distribution and orbital torque-conversion architecture associated with LSHT motor applications.

High Torque Density

Danfoss lists up to 972 N·m continuous torque and 1,181 N·m intermittent torque at the 4000 Series platform level. Exact output remains dependent on displacement and operating condition.

For the supplied configurations, public technical data indicate approximately 705 N·m for 109-1118-006 and 600 N·m for the 205.5 cm³/rev configuration represented by 109-1319-006.

Tapered Roller Bearings

The exact 109-1118-006 configuration uses front and rear tapered roller bearings, supporting radial and axial loading within the specified mechanical envelope.

Multiple Shaft Configurations

The 4000 Series supports several output-shaft designs, including:

• 1-1/4-inch straight keyed
• 1-5/8-inch tapered
• 1-1/4-inch 14T spline
• 1-1/2-inch 17T spline
• 40 mm straight shaft.

This flexibility is useful for replacement engineering, but it also makes full part-number verification essential.

SAE B Four-Bolt Mounting

The two supplied models use the same basic AB SAE B mounting family, while their shaft configurations differ:

• 109-1118-006: 14T splined shaft
• 109-1319-006: 1-1/4-inch straight keyed shaft.

Therefore, matching displacement and mounting flange alone does not establish direct interchangeability.

SAE O-Ring Porting

Both configurations use SAE O-ring port systems. The 109-1118-006 exact PowerSource record specifies 1-1/16-12 SAE O-ring side ports plus a 7/16-20 SAE O-ring drain port with check valve; the 109-1319-006 model code uses the equivalent AB / 02 port and case-flow codes.

Material and Manufacturing Data Boundary

Secondary technical listings identify the Char-Lynn 4000 Series housing as cast iron. However, the reviewed Danfoss/Eaton documents do not publish specific steel grades, heat-treatment hardness, case depth or machining tolerances for these two complete part numbers. Such values should not be invented for a B2B product page.

Application Areas

Danfoss’s official 4000 Series product page specifically identifies:

• Mowing
• Snow removal
• Sprayer equipment
• Trenching
• Wood-product machinery.

The same LSHT architecture is also relevant to:

• Agricultural machinery
• Conveyor drives
• Material-handling equipment
• Hydraulic winches
• Industrial rotary drives
• Forestry-related equipment
• Mobile hydraulic machinery
• Auxiliary hydraulic drives

Expert Maintenance Tips

Verify the Complete Model Code

For 109-1118-006 and 109-1319-006, confirm:

• Mounting code
• Shaft code
• Port code
• Case-flow code
• Seal option
• Accessories
• Geroler option
• Paint/packaging
• Design code.

Check the Shaft Configuration

109-1118-006:

• 1-1/4-inch
• 14T spline
• 3/8-16 UNC-2B end thread.

109-1319-006:

• 1-1/4-inch straight shaft
• Square key
• 3/8-16 UNC-2B shaft-end thread.

Even with the same SAE B mounting pattern, these shaft interfaces are not automatically interchangeable.

Verify Port Orientation and Case Drain

Check:

• Main-port size
• Port orientation
• Staggered-port geometry
• Case-drain connection
• Check-valve configuration

The exact 109-1118-006 PowerSource page provides these values directly.

Respect Intermittent Duty

Danfoss defines 4000 Series intermittent operation as approximately six seconds per minute. Therefore, the 310-bar intermittent rating must not be marketed as a continuous pressure rating.

Maintain Hydraulic Cleanliness

Clean the motor and fittings before disconnecting hydraulic lines, cap open ports immediately and prevent contamination from entering the disc valve, Geroler, bearings and seal system.

Calculate External Shaft Loads

When the motor drives a sprocket, pulley, hub or other overhung load, calculate actual radial and axial forces from:

• Shaft speed
• Load location
• Mounting flange
• Shaft geometry
• Output torque

Avoid applying a generic load number to every 4000 Series configuration.

Perform 100% Simulated Working-Condition Testing

For an aftermarket replacement motor, a final validation program should include:

• No-load startup
• Forward/reverse rotation
• Low-speed stability
• Rated-flow response
• Differential-pressure response
• External-leak inspection
• Case-drain verification
• Shaft-running inspection
• Port/interface verification

This makes 100% Simulated Working-Condition Testing a concrete engineering quality-control process rather than a generic marketing statement.
