Wacker Neuson 5100000355 Cylinder Head Gasket

The Wacker Neuson Cylinder Head Gasket is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 walk-behind concrete trowels, PT3A centrifugal trash pumps, BFS floor saws, BPU reversible vibratory plates, GV and GP portable generators, and HPG vibratory truss screed power sections. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, part number is manufactured to the same specification as the original, ensuring a proper combustion seal without rework or modification. This gasket is a critical engine service component and is the correct choice when rebuilding or resealing the cylinder head on any of the compatible models listed. Verify your model number before ordering to confirm fitment across this broad cross-family application range.

Key Features

• Correct Combustion Chamber Seal — Engineered to maintain the precise compression and heat tolerances required by the shared engine platform used across CT trowels, PT3A pumps, BFS saws, BPU plates, and GV/GP generators.
• Genuine OEM Quality — Manufactured to Wacker Neuson's original specification, using gasket materials rated for the combustion temperatures and cylinder pressures of this engine family — no guesswork on material grade or thickness.
• Direct Drop-In Replacement — Matches the original bolt pattern, bore diameter, and thickness of the factory gasket, allowing straightforward installation during any cylinder head removal or top-end engine service.
• Broad Cross-Family Fitment — A single part number covering CT36 and CT48 trowels, PT3A trash pumps, BFS 914 and BFS 940 floor saws, BPU 3050/3750/4045 reversible plates, GV/GP generators, and HPG screed power sections — reducing the number of unique parts to stock.
• Protects Engine Integrity — A failed or worn head gasket allows combustion gases to escape, leading to power loss, overheating, and internal engine damage. Replacing with the correct OEM gasket restores compression and prevents coolant or oil contamination of the combustion chamber.
• Critical Fuel and Emission System Compliance — A properly sealing head gasket is essential to maintaining correct air-fuel combustion ratios and exhaust integrity — particularly important on equipment subject to emissions standards in EU and regulated US markets.

The cylinder head gasket sits between the engine block and the cylinder head, creating a gas-tight, fluid-tight seal that contains combustion pressure and prevents engine oil or coolant from entering the combustion chamber. It is one of the most thermally stressed seals in any small engine, expanding and contracting with every heat cycle. When a head gasket fails — through age, overheating, or improper torque — the result is a loss of compression, white or blue exhaust smoke, engine misfires, or fluid mixing that can quickly destroy internal engine components. Replacing it with the correct OEM-spec gasket during any top-end engine service is the surest way to restore full engine output and prevent repeat failures.
