Wacker Neuson 5000151053 Key 5 X 5 X 33

The Wacker Neuson is a genuine OEM Key 5 X 5 X 33 designed for Wacker Neuson VP, WP, WPP, AP, and WPU series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this key carries the same part number and specification as the original component installed at the factory. Confirmed fitment spans a wide range of plate compactor models including the VP1135A, VP1550A, VP1340A, VP2050A, VP1030A, WP1030A, WP1235A, WP1540A, WP1550A, WP2050A, WPP1540A, WPP1550A, WPU1550A, AP1135A, AP1550A, and MP15A, among others.

Key Features

• Genuine OEM Dimensional Accuracy — Machined to the exact 5 x 5 x 33 mm profile specified by Wacker Neuson, ensuring the key seats fully in the keyway without play or slippage.
• Direct Drop-In Installation — Matches the original keyway geometry on VP, WP, WPP, AP, and WPU plate compactor drive shafts for a straightforward swap with standard hand tools.
• Broad Compactor Compatibility — Fits across multiple generations of Wacker Neuson single-direction vibratory plate compactors, covering VP1030A through VP2050A, WP1030A through WP2050A, WPP, WPU, and AP series models.
• Drive Torque Transmission — Maintains the positive mechanical connection between the shaft and driven component; a worn or missing key causes immediate loss of drive and accelerated damage to mating parts.
• Corrosion-Resistant Steel Construction — Built from hardened steel stock consistent with OEM specification, resisting the vibration, moisture, and debris exposure typical of compaction work.

A woodruff or parallel drive key is a small but critical component that locks a rotating shaft to a hub, pulley, or gear, preventing the two parts from spinning independently of each other. On a vibratory plate compactor, the key transmits torque from the engine output shaft to the exciter or drive assembly that generates the compaction force. When a key shears, rounds off, or goes missing, the drive connection is lost — the engine runs but the plate produces no vibration and the machine cannot compact. Replacing a worn key promptly protects the keyway itself; if the keyway becomes damaged from a loose key, the repair becomes significantly more involved and costly.
