The Wacker Neuson Cylinder Head Gasket is a genuine OEM component designed for PTS4V series centrifugal trash pumps, GPS8500 and GS8.5V portable generators, and the RD11V tandem roller. Sourced directly from Wacker Neuson, this gasket delivers an exact match to the original specification, ensuring a proper head seal on first installation. Confirmed fitment spans the PTS4V, PTS4V(I), GPS8500, GS8.5V, and RD11V — covering a wide range of Wacker Neuson equipment built around the same engine platform.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original combustion-pressure and temperature tolerances required by Wacker Neuson engines, ensuring consistent compression seal integrity across all operating conditions.
- Drop-In Head Replacement — Matches the original bolt pattern and bore diameter exactly, allowing direct installation without trimming or shimming when re-torquing the cylinder head.
- Broad Wacker Neuson Fitment — Compatible with PTS4V and PTS4V(I) trash pumps, GPS8500 and GS8.5V portable generators, and the RD11V tandem roller — all sharing a common engine platform.
- Restores Full Compression — A failed or blown head gasket causes lost compression, hard starting, and overheating; replacing with part 5000111432 restores the combustion seal and brings the engine back to full operating pressure.
- Fuel and Combustion Safety — A correctly seated cylinder head gasket prevents combustion gases from escaping into the cooling or oil passages, reducing the risk of engine damage, oil contamination, and uncontrolled exhaust leaks.
The cylinder head gasket forms the critical seal between the engine block and the cylinder head, containing combustion pressure and preventing coolant or oil from migrating into the combustion chamber. When the gasket fails — whether from overheating, improper torque, or age — compression drops, oil and coolant can mix, and the engine will run poorly or not at all. Replacing the gasket promptly with the correct OEM part protects the engine internals and restores reliable power output.
