The Wacker Neuson Cylinder Head Complete is a genuine OEM component designed for a wide range of Wacker Neuson vibratory plates, generators, pumps, and concrete equipment — including the GV2500A, WP1540A, WP1550A, BPU2540A, VP-series vibratory plates, PT2A trash pumps, and BT-series internal vibrators. Sourced directly from Wacker Neuson, this cylinder head assembly meets the same specifications as the original part installed at the factory. It is a direct-fit replacement for all compatible models, including WPU1550AW, HP50A, HPG50A, HPG100A, and the A5000/160 series, covering a broad cross-section of the Wacker Neuson gasoline-powered equipment lineup.
Key Features
- Genuine OEM Combustion Integrity — Manufactured to Wacker Neuson's original tolerances for combustion chamber geometry, port sizing, and sealing surface finish, ensuring correct compression and fuel-air mixture performance.
- Direct-Fit Assembly — Supplied as a complete cylinder head assembly with all sub-components pre-installed, dropping straight onto the engine block with no additional machining or adaptation.
- Broad Model Coverage — Compatible with GV2500A generators, WP1540A/WP1550A/VP-series vibratory plates, PT2A pumps, BT24A/BT36A internal vibrators, HP/HPG screed power sections, and more.
- Restored Engine Output — A cracked, warped, or leaking cylinder head starves the engine of compression, causing hard starts, power loss, and excessive fuel consumption; replacing it with 5100050549 restores full operating performance.
- Combustion Seal Safety — A correctly seated OEM cylinder head prevents combustion gas blow-by and coolant or oil intrusion into the combustion chamber, reducing the risk of uncontrolled engine behavior on the worksite.
The cylinder head sits at the top of the engine block and forms the upper boundary of the combustion chamber. It houses the intake and exhaust valves, provides mounting points for the spark plug, and works together with the head gasket to maintain the compression seal essential for efficient combustion. When a cylinder head warps, cracks, or develops a blown seal, compression drops sharply — leading to difficult starting, rough running, and eventual engine failure if left unaddressed. Replacing the cylinder head complete restores the engine's ability to generate consistent power and run cleanly under load.
