The Wacker Neuson Cap is a genuine OEM Cap designed for the D4000 Diesel Power Unit, DPU 100-70 Vibroplate series, DPU 100-70Le Reversible Vibratory Plate, and L5000/225 ISO and ANSI variants. As a factory-sourced component, it is manufactured to the exact dimensions and material standards required by Wacker Neuson for these machines. Replacing a worn, cracked, or missing cap with the correct OEM part ensures the protected port or fitting performs as originally intended. Cross-reference part number against your model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to the exact material and dimensional tolerances specified for this Cap, ensuring a correct seal and secure retention on the intended port or fitting.
- Direct OEM Replacement — Matches the original Cap's profile and thread or press-fit engagement, so installation is straightforward with no rework needed.
- Broad Series Compatibility — Fits the D4000 Diesel Power Unit, DPU 100-70 and DPU 100-70Le Vibroplate and Reversible Vibratory Plate models, and L5000/225 ISO and ANSI machines.
- Protects Critical Openings — A properly fitted cap keeps contaminants, moisture, and debris out of the port it covers, preserving the integrity of the surrounding system.
- Traceability You Can Trust — Sourced directly through the Wacker Neuson OEM supply chain, so part number 5000203726 is the correct, current reference for this application.
A cap serves as a protective closure for an exposed port, fitting, or reservoir opening on the machine. Its primary role is to seal that opening against the ingress of dirt, moisture, and debris while the machine is in operation or in storage. When a cap is cracked, missing, or improperly seated, contaminants can enter sensitive systems, leading to accelerated wear, fluid contamination, or component damage that extends well beyond the cap itself.
