The Wacker Neuson is a genuine OEM Woodruff Key designed for a broad range of Wacker Neuson compaction equipment, including the BV50A-P and BV50A-H backpack vibrators, BS50-4As and BS60-4As vibratory rammers, and VP1030A and WP1030A single-direction vibratory plates. As a genuine OEM component, the is manufactured to the same tolerances and material specification as the original part that left the factory, ensuring a correct, secure fit within the shaft-and-hub assembly it serves. If you are sourcing a replacement for worn, sheared, or missing Woodruff Key hardware across any of these machine families, part number is the verified, direct replacement.
Key Features
- OEM-Grade Material and Tolerancing — Manufactured to exact Wacker Neuson hardness and dimensional specifications, ensuring the key seats fully in the keyway and transfers torque without slipping or deforming under load.
- Direct Drop-In Replacement — Matches the original keyway profile and radius of the Woodruff seat, so installation requires no filing, grinding, or shimming.
- Wide Compaction Equipment Compatibility — Verified fitment across BV50A-P and BV50A-H backpack vibrators, BS50-4As and BS60-4As vibratory rammers, and VP1030A and WP1030A vibratory plates.
- Protects Shaft and Hub from Torque Damage — A correctly fitted Woodruff Key prevents hub-to-shaft slippage; running without one — or with a worn key — accelerates wear on both the shaft and the hub bore, leading to costly component replacement.
- Critical Drive-Train Safety Component — In rammers and vibratory plates, a failed or missing Woodruff Key can cause sudden loss of eccentric or crankshaft drive engagement, making prompt replacement essential for safe, controlled operation.
A Woodruff Key is a small, semi-circular metal key that seats into a curved keyway machined into a rotating shaft, with the flat face engaging a corresponding slot in the mating hub, pulley, or gear. Its job is to lock the hub and shaft together rotationally so that torque is transmitted reliably without the two components spinning independently of each other. When a Woodruff Key shears, deforms, or falls out — which can happen under shock loads or after extended service — the driven component loses its connection to the shaft entirely, resulting in loss of eccentric motion in a vibratory plate or rammer and potential secondary damage to the shaft and hub surfaces if the machine is operated in that condition.
