Wacker Neuson 1000360910 Visco Coupling

The Wacker Neuson is a genuine OEM Visco Coupling designed for the TH627 series. Sourced directly from Wacker Neuson, this part meets the same specifications as the original component installed at the factory, ensuring a correct, dependable installation. The is the verified OEM part number for TH627 applications, giving you confidence that you are ordering the right part for your machine.

Key Features

• OEM-Matched Viscous Resistance: Engineered to the same fluid viscosity and torque transfer characteristics as the original, so the coupling performs exactly as intended within the drivetrain.
• Direct Drop-In Replacement: Mounts to the same bolt pattern and interface as the original unit, requiring no modification to existing brackets or connections.
• Confirmed TH627 Fitment: Verified against Wacker Neuson spare parts list 418-02 for the TH627, so you can order with confidence.
• Protects Downstream Components: A properly functioning visco coupling controls the transfer of rotational load to the cooling fan, preventing overloading of the engine and associated drive components during temperature swings.
• Genuine OEM Quality: Supplied as an authorized Wacker Neuson OEM part, manufactured to the same material and dimensional standards as the component it replaces.

A visco coupling — also known as a viscous fan coupling — controls the speed at which the engine cooling fan operates by using a silicone fluid that thickens in response to heat. When the engine is cool, the coupling allows the fan to freewheel at a reduced speed, limiting unnecessary load on the engine. As operating temperature rises, the fluid engages more firmly, driving the fan faster to pull additional airflow through the radiator. When the coupling fails or wears out, the fan may not respond correctly to engine temperature, leading to overheating or excessive fan drag that strains the engine.
