The Wacker Neuson 5100026386 is a genuine OEM Cylinder Head Cover designed for DPU80 and DPU90 series reversible vibratory plate compactors. As a direct OEM replacement, this part is manufactured to the same specifications as the original component, ensuring a correct, trouble-free installation on your machine. It is compatible with a wide range of DPU80 and DPU90 models including the DPU80Lec770, DPU80Lem770, DPU90Lec770, DPU90Lem770, DPU80rLec770, DPU90rLec770 US, DPU90rLem770 US, and additional Lec670 and Lem670 variants. When your existing cover is cracked, warped, or leaking, replacing it with the genuine Wacker Neuson 5100026386 restores proper engine sealing and protects internal valve train components.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to OEM material and dimensional standards, ensuring the cover seats flush against the cylinder head gasket surface without distortion or oil weepage.
- Direct Bolt-On Replacement — Matches the original mounting pattern and port configuration of DPU80 and DPU90 engines, dropping straight into place with existing hardware.
- Broad DPU80 and DPU90 Coverage — Fits Lec670, Lec770, Lem670, Lem770, and rL reversible variants, including US-market models, covering a wide spread of heavy-duty reversible plate compactor configurations.
- Protects Valve Train Components — A properly sealed cylinder head cover keeps oil in and contaminants out, maintaining lubrication to the rocker arms and valves for consistent engine performance under sustained compaction loads.
- Fuel and Oil Safety Compliance — A failed or cracked cover allows oil to escape onto hot engine surfaces, creating a fire and slip hazard on the worksite; replacing with a genuine OEM cover restores compliant, safe operation.
The cylinder head cover — sometimes called a valve cover — bolts to the top of the engine's cylinder head and seals the upper valve train cavity. It keeps engine oil contained within the rocker arm and camshaft area, preventing leaks while also shielding those components from dust, debris, and moisture that are present in heavy compaction environments. When the cover cracks, warps, or its gasket surface deteriorates, oil escapes onto the engine block and surrounding components, leading to oil loss, contamination risk, and potential overheating of the valve train. Replacing a damaged cover promptly with a correctly fitting OEM part is one of the most straightforward engine maintenance steps for keeping a DPU-series compactor running cleanly and reliably on site.
