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, GP and GPi portable generators, BFS floor saws, BPU reversible vibratory plates, and PDT and PG series pumps. As a genuine OEM component, the is manufactured to the same standards as the original part installed at the factory, ensuring consistent fit and function across all covered models. This Fitting Key serves as a common shared component across multiple Wacker Neuson product families, making it a practical stocking part for dealers, rental fleets, and field service teams. Confirm your model and serial number against the fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Tolerancing — Sourced directly from Wacker Neuson, this Fitting Key is machined to the exact dimensional spec required for secure shaft-to-hub engagement across all covered models.
• Drop-In Replacement — Matches the original keyway geometry for straightforward installation without filing, shimming, or modification to mating components.
• Wide Cross-Family Fitment — Compatible with CT36 and CT48 power trowels, VP and WP vibratory plate compactors, PT2/PT3 trash pumps, GP/GPi/GPSi portable generators, BFS floor saws, BPU reversible plates, and PDT/PG diaphragm and dewatering pumps.
• Positive Power Transfer — A correctly seated Fitting Key locks rotating components together so drive force is transmitted without slippage; a worn or missing key causes component slip, rapid wear, and loss of output.
• Drive Safety Compliance — Keyed shaft connections are a critical mechanical safety feature; using a correctly sized OEM key prevents shaft-to-hub fretting that can lead to sudden disconnection of driven components under load.

A Fitting Key is a small, precisely sized metal piece seated in a machined slot — called a keyway — cut into both a shaft and the hub of a mating component such as a pulley, sprocket, or impeller. Its job is to lock those two parts rotationally so that torque from the driving shaft is transferred cleanly to the driven component without any slippage. When a Fitting Key wears, shears, or falls out, the driven component can spin freely on the shaft, immediately halting the machine's output — whether that is plate compaction force, pump flow, or generator power. Replacing a failed or missing key with a correctly dimensioned OEM part restores full mechanical engagement and protects the mating keyway slots from the accelerated wear that occurs when a key is undersized or made from the wrong material.
