Wacker Neuson 5200000466 Cylinder Head Cover

The Wacker Neuson Cylinder Head Cover is a genuine OEM component designed for a wide range of Wacker Neuson walk-behind concrete power trowels, portable generators, and reversible vibratory plate compactors. This is a direct OEM replacement sourced to the original specification, covering the CT36-8A, CT36-8A-V, CT48-8A, CT48-11A, and CT48-13A-V trowel series, GP5600A, GP6600A, GPS5600A, GPS6600, GV3800, GV5600, and GV6600 generator models, as well as BPU 3050A, BPU 3750Ats, BPU 4045A, and BPU 5545A reversible plate compactors. As a genuine Wacker Neuson part, the is manufactured to the same standards as the original, ensuring correct fit and sealing performance across all listed machines. Keeping this cover in good condition protects the engine's valve train and maintains consistent engine operation across every application.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional spec, delivering the correct compression and sealing performance expected of a cylinder head cover on these engines.
• Drop-In Engine Compatibility — Mounts directly using the original fastener pattern and gasket interface; no reworking of the mating surface required.
• Broad Cross-Family Fitment — A single part number covers CT36 and CT48 concrete trowels, GP/GPS/GV-series portable generators, and BPU-series reversible vibratory plate compactors — making it a versatile stocking part for mixed fleets.
• Protects the Valve Train — A correctly seated cylinder head cover contains oil mist and excludes debris from the valve and rocker arm area; a cracked or poorly sealing cover leads to oil leaks, contamination, and accelerated valve train wear.
• Oil Leak Prevention — Replacing a worn or damaged cover promptly stops external oil loss that can create slip hazards on the work surface and cause engine oil starvation over time.

The cylinder head cover bolts to the top of the engine's cylinder head and seals the valve train compartment — the area housing the rocker arms, valve springs, and associated components. Its primary job is to contain the pressurized oil mist that lubricates those moving parts while keeping dirt, water, and debris out. When the cover cracks, warps, or its sealing surfaces degrade, oil seeps out externally and contaminants can enter, accelerating wear on the rocker arms and valves and leading to harder starts, rough running, and eventual engine damage if left unaddressed. Replacing the 5200000466 restores the sealed environment the engine needs to maintain proper lubrication and valve timing function.
