The Multiquip 11465111950 Head Cover Assembly is a genuine OEM component designed for MDR-9DYE power trowels, MVH-304DSB and MVH-402DSB reversible plate compactors, and MRH-800DS walk-behind rollers. Sourced directly from Multiquip, this assembly delivers the exact fit and material quality required to maintain your equipment's performance. Whether you're servicing a plate compactor on a paving job or maintaining a walk-behind roller between shifts, this is the correct replacement part for the application. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material specifications as the original, ensuring the cover seats and seals correctly against the engine head without gaps or misalignment.
- Direct-Fit Replacement — Engineered as a drop-in assembly for compatible models, with mounting points and dimensions that align with the original hardware configuration.
- Broad Fitment Across Equipment Families — Compatible with MDR-9DYE power trowels, MVH-304DSB and MVH-402DSB reversible plate compactors, and MRH-800DS walk-behind rollers — one part number serving multiple machine types.
- Engine Protection — A properly fitted head cover keeps contaminants out of the valve train and retains oil vapor within the engine housing, directly supporting engine longevity and consistent output.
- Fuel and Oil Safety — A cracked or poorly seated head cover can allow oil mist to escape near hot engine surfaces, creating a fire and contamination risk; replacing it promptly with an OEM assembly restores safe operating conditions.
The head cover assembly mounts over the top of the engine's cylinder head, enclosing the valve train and rocker arm area. Its primary role is to contain oil splash and vapor generated by the valvetrain during operation, preventing leaks and keeping contaminants from entering the engine. When a head cover cracks, warps, or loses its sealing integrity, oil can escape onto hot engine components or surrounding machine surfaces — leading to smoke, oil loss, and potential engine damage over time. Replacing a worn or damaged cover assembly restores the sealed engine environment the machine depends on to run cleanly and efficiently.
