Wirtgen Coupling 115331 (CM5000) for W1900, W2000, W195, W205, W215
Product Summary
This is a coupling (part number 115331, cross-reference CM5000) used in Wirtgen milling machines to transmit torque from the engine to the hydraulic pump or milling drum drive. It also compensates for minor misalignment, absorbs shock loads, provides overload protection, and reduces transmission noise. The coupling body is made of steel, and the flexible element is made of composite silicone rubber, offering excellent wear resistance and high-temperature tolerance. Overall outer diameter is 425 mm, and the unit weighs 15.2 kg. We supply this coupling as a new unit, available as either original or aftermarket. Fitment must be verified using your machine model and existing part number before ordering.

Product Function
The coupling is a critical component in the drive line of a milling machine. It performs several important functions:
- Torque transmission – Transfers engine power to the hydraulic pump or milling drum drive.
- Misalignment compensation – Allows small radial, axial, or angular misalignments between the engine shaft and driven shaft, protecting bearings from excessive loads.
- Shock absorption – The flexible element absorbs impact loads caused by uneven milling conditions, preventing damage to the crankshaft or hydraulic pump.
- Overload protection – Under extreme overload, the coupling may slip or break, acting as a sacrificial fuse to protect more expensive components.
- Noise reduction – Isolates metal-to-metal contact and reduces mechanical noise.
Regular inspection of the flexible element is recommended, as wear or cracking can lead to increased vibration and eventual drive failure.
