The Wacker Neuson is a genuine OEM Fitting Key designed for BPU and DPU series reversible vibratory plate compactors. This direct-replacement component is sourced from Wacker Neuson and engineered to original specifications, covering an extensive range of BPU and DPU models including the BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, DPU 6555H, DPU 130Le, and their regional and configuration variants. As a genuine OEM part, the Fitting Key matches the original component exactly — no guesswork, no rework, just a straightforward installation that restores your machine to proper working order.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring correct engagement and retention within the drive or shaft assembly it secures.
- Broad BPU and DPU Compatibility — Fits a wide range of Wacker Neuson reversible vibratory plate compactors across the BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, and DPU 4045 through DPU 6555 model families, including diesel and gasoline variants.
- Drop-In Replacement — Matches the original key profile exactly, seating into its keyway without any machining, shimming, or adaptation of mating components.
- Torque Transfer Integrity — A worn or missing fitting key causes slippage between the shaft and mating component, leading to erratic compaction output and accelerated wear on connected parts; a correctly fitted key restores full, consistent torque transmission.
- Wide Variant Coverage — Covers regional configurations including US, EU, AP, CH, and EC variants, as well as specialized builds such as the DPU 130Le and DPU6555Hechzf, making this a single part number that serves a large portion of the reversible plate compactor fleet.
A fitting key is a small but critical component that locks a rotating shaft to its mating hub, pulley, or drive element, ensuring that rotational force is transmitted without slippage. In a reversible vibratory plate compactor, this precise connection is essential for delivering consistent compaction energy to the exciter mechanism. When a fitting key wears, shears, or goes missing, the connected component can spin freely on the shaft, causing loss of vibration output, unusual noise, and rapid damage to the shaft and hub surfaces — turning a minor part replacement into a much costlier repair.
