Wacker Neuson 5000115586 Flexible Coupling Kit

The Wacker Neuson Flexible Coupling Kit is a genuine OEM component designed for the PT6LT and PT6LS series 6-inch self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this kit delivers the exact fit and material specification required to restore proper drive connection between the engine and pump end. It is confirmed compatible across multiple PT6LT and PT6LS configurations, including trailer-mounted, skid-mounted, and Tier 4 variants. Keep a on hand to minimize unplanned service interruptions on high-volume pumping jobs.

Key Features

• Genuine OEM Elastomeric Integrity — Made to Wacker Neuson's original material and durometer specification, ensuring the coupling element absorbs torsional shock without cracking or glazing under continuous pump load.
• Kit Format for Complete Service — Includes all components needed for a full coupling replacement in a single part number, so technicians aren't sourcing individual pieces separately.
• Broad PT6 Series Coverage — Fits PT6LT (trailer-mounted) and PT6LS (skid-mounted) configurations, including standard, Tier 4, and international variants across multiple machine numbers.
• Protects Engine and Pump Alignment — A correctly functioning flexible coupling compensates for minor shaft misalignment and dampens vibration; a worn or failed coupling accelerates bearing wear on both the engine and pump end.
• Direct OEM Replacement — Matches the original hub geometry and spider element profile, allowing straightforward installation without machining or shimming.

The flexible coupling sits between the engine output shaft and the pump impeller shaft, transmitting rotational drive while absorbing vibration and accommodating minor axial or angular misalignment. The elastomeric spider element at its center acts as a buffer — without it, raw engine torque pulses would transfer directly into the pump housing, stressing bearings and seals far beyond their design limits. When the coupling element wears, cracks, or loses its elasticity, operators typically notice increased vibration, noise at startup, or a gradual drop in pump output as the drive connection becomes inconsistent.
