Wacker Neuson 5100011421 Cover (Bayonet Lock)

The Wacker Neuson 5100011421 is a genuine OEM Cover (Bayonet Lock) designed for the DPU80, DPU90, and DPU110 series reversible vibratory plate compactors. As a direct factory replacement, this cover is manufactured to the same tolerances and material specifications as the original component installed at the factory. Fitment spans a wide range of DPU-series models including standard, reversible (r), and US-market variants across the Le, Lec, Lem, and KMAT configurations. Keeping this cover in good condition is essential to protecting the components it shields from contamination and mechanical damage on the jobsite.

Key Features

• Genuine OEM Construction — Manufactured by Wacker Neuson to original material and dimensional specifications, ensuring the bayonet locking mechanism engages and retains securely without play or premature wear.
• Bayonet Lock Retention — The integrated bayonet lock interface allows for tool-free engagement and positive locking, matching the original mounting design without any adaptation to the housing.
• Broad DPU-Series Compatibility — Confirmed fitment across DPU80, DPU80r, DPU90, DPU90r, DPU110, and DPU110r variants, including Le, Lec, Lem, and KMAT platform configurations in both standard and US-market versions.
• Protective Coverage — Shields internal or adjacent components from dust, aggregate, and moisture intrusion common in soil and aggregate compaction environments, helping maintain the integrity of protected systems over extended service cycles.
• Direct OEM Sourcing — Part number 5100011421 is the factory-designated replacement, eliminating guesswork when sourcing through authorized Wacker Neuson parts channels.

The Cover (Bayonet Lock) on a DPU-series reversible plate compactor serves as a protective housing component that encloses and secures an underlying assembly using a twist-and-lock bayonet interface. This style of fastening allows operators or technicians to open and reseat the cover quickly without tools, while still maintaining a firm, vibration-resistant connection during machine operation. When the cover becomes cracked, broken, or loses its locking ability, the components beneath are exposed to the harsh conditions of compaction work — including dust, debris, and moisture — which can accelerate wear or cause premature failure of protected parts.
