The Wacker Neuson is a genuine OEM Fitting Key designed for a broad range of Wacker Neuson equipment, including BFS floor saw series, CT and CRT concrete trowel series, BPU reversible vibratory plate compactors, PT trash pumps, and RS single-drum vibratory rollers. As a genuine OEM component, the is manufactured to Wacker Neuson's exact tolerances and specifications, ensuring a direct, drop-in installation with no guesswork. This single part number covers an extensive list of models across multiple product families, making it a high-demand service item for dealers, rental fleets, and contractors maintaining mixed fleets of Wacker Neuson equipment. Confirm your model number against the fitment list before ordering to ensure correct application.
Key Features
- Genuine OEM Precision — Manufactured by Wacker Neuson to exact dimensional tolerances, ensuring the key seats and locks correctly within the keyed shaft or hub assembly without slop or misalignment.
- Direct Drop-In Installation — Matches the original keyway profile of the host shaft or component, allowing straightforward installation with standard hand tools and no custom fitting.
- Wide Cross-Family Fitment — A single part number covering BFS floor saws, CT and CRT concrete trowels, BPU reversible vibratory plate compactors, PT trash pumps, and RS vibratory rollers — ideal for multi-machine service inventory.
- Drivetrain Integrity — A correctly sized and seated fitting key locks rotating components to their shafts, preventing slippage under load. A worn or missing key causes drive loss, component damage, and accelerated wear to the shaft and hub.
- Verified OEM Part Number — Part number 5000074686 is the factory-authorized replacement, cross-referenced across all listed model configurations for confident ordering.
A fitting key is a small but mechanically critical component that sits in a machined slot — called a keyway — between a rotating shaft and a hub, pulley, blade adapter, or drive component. Its job is to transmit torque between the two parts, keeping them locked together rotationally so power is transferred without slippage. Because it bears repeated shear stress during every start, stop, and load cycle, a fitting key can shear, deform, or wear over time — especially in high-vibration equipment like floor saws, trowels, and vibratory compactors. When a fitting key fails, the driven component spins free of the shaft, causing immediate loss of function and potential damage to the keyway itself, which is far more costly to repair.
