Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component — ensuring a correct, drop-in fit without guesswork. Compatible across multiple PT6Y and PT6YT configurations, including PT6Y-AU and PT6YT-IN variants, the is the right call when you need a dependable, authorized replacement that keeps your pump running as intended.

Key Features

• Genuine OEM Torque Transfer Integrity — Manufactured to Wacker Neuson's original coupling tolerances, ensuring consistent power transmission between the engine and pump end without slippage or misalignment.
• Direct-Fit Replacement — Engineered to install in the same position and orientation as the original, with matching interface dimensions for the PT6Y and PT6YT pump drive assemblies.
• Broad PT6 Series Coverage — Fits PT6Y, PT6YT, PT6Y-AU, PT6YT-IN, and PT6Y EPA T4 models, covering a wide range of Wacker Neuson 3-inch trash pump configurations.
• Sustained Pump Output — A correctly functioning coupling maintains smooth, uninterrupted drive engagement; a worn or failed coupling leads to power loss, vibration, and pump stall under load.
• Authorized Wacker Neuson Part — Part number 5100059185 is an official Wacker Neuson replacement, traceable through authorized distribution channels for full part number confidence.

The coupling on a trash pump connects the engine's drive shaft to the pump impeller assembly, transferring rotational power so the pump can move water and solids effectively. It acts as the mechanical link between power source and pump end, absorbing minor misalignment and vibration during operation. When a coupling wears, cracks, or fails, drive engagement becomes inconsistent — resulting in reduced flow, rough operation, or a complete loss of pumping function until the part is replaced.
