Wacker Neuson 5000156464 Fitting Key

The Wacker Neuson is a genuine OEM Fitting Key designed for a broad range of Wacker Neuson equipment, including CT36 and CT48 concrete power trowels, VP and WP series single-direction vibratory plate compactors, PT2 and PT3 centrifugal trash pumps, GP2600 and GP4000 portable generators, and numerous other models across the Wacker Neuson lineup. As a genuine OEM part, the is sourced directly through Wacker Neuson's authorized supply chain, ensuring it meets the exact specifications of the original component it replaces. This fitting key is confirmed across an extensive range of machine families, making it a high-utility service part for dealers and operators maintaining multiple Wacker Neuson units. Always cross-reference your machine's model number and serial number before ordering to confirm compatibility with your specific unit.

Key Features

• Genuine OEM Material Integrity — Manufactured to Wacker Neuson's exact tolerances, ensuring the key seats correctly in its keyway without slipping, deforming, or causing shaft damage over time.
• Direct Drop-In Replacement — Matches the original profile and dimensions so it installs directly into the keyway slot without filing, shimming, or modification to the shaft or hub.
• Broad Cross-Family Fitment — Confirmed for CT36 and CT48 power trowels, VP and WP vibratory plate compactors, PT2 and PT3 trash pumps, GP2600 and GP4000 generators, and additional Wacker Neuson models — one part number covering multiple machine families.
• Prevents Torque Loss and Component Damage — A worn or missing fitting key allows the driven component to spin independently of the shaft, causing rapid wear to both the hub and shaft; replacing it promptly restores full torque transmission and protects surrounding components.
• Safety-Critical Drivetrain Component — On power trowels, compactors, and pumps, a failed fitting key can cause sudden loss of drive to rotating assemblies; using the correct OEM key ensures the connection holds under rated operating loads.

A fitting key is a small, precisely dimensioned piece that sits in a machined slot — called a keyway — between a rotating shaft and the hub of a driven component such as a belt pulley, impeller, or drive disc. Its job is to lock the two parts together rotationally so that torque from the engine or motor is transferred cleanly to the driven assembly without slipping. When a fitting key shears, deforms, or goes missing, the shaft spins freely inside the hub, the driven component stops turning, and the machine loses function entirely — often with rapid secondary damage to the keyway surfaces. Replacing a worn or damaged fitting key with the correct OEM part restores the mechanical connection and prevents further deterioration of the shaft and hub.
