The Wacker Neuson Gasket for Cylinder Head is a genuine OEM component designed for MDP3 and PT3c series diaphragm trash pumps. As a factory-sourced part, it is manufactured to the exact material and dimensional specifications required by Wacker Neuson, ensuring a proper seal at the cylinder head interface. This gasket is the correct replacement for MDP3, MDP3X, and PT3c machines, making part verification straightforward before you order.
Key Features
- OEM Sealing Material Grade — Manufactured to Wacker Neuson's exact material specification, delivering the compression resistance and thermal tolerance required at the cylinder head joint.
- Direct Drop-In Replacement — Matches the original bolt pattern and profile for the MDP3 and PT3c cylinder heads, seating correctly without modification to mating surfaces.
- Confirmed Fitment for MDP3 and PT3c Series — Compatible with MDP3, MDP3X 75mm/3in diaphragm trash pumps, and PT3c models, covering the core MDP3 and PT3c pump families.
- Maintains Combustion Integrity — A correctly seated cylinder head gasket holds compression and prevents combustion gases from escaping, keeping the engine running at full power output.
- Fuel System Safety — A failed or improperly seated head gasket can allow combustion gases to leak near fuel components; replacing with a genuine OEM part restores the correct sealed boundary and supports safe pump operation.
The cylinder head gasket sits between the engine block and the cylinder head, forming a pressure-tight seal that contains combustion gases and maintains the correct compression ratio inside the cylinder. It also prevents coolant or oil from migrating into the combustion chamber or escaping externally. When a head gasket fails or degrades — through heat cycling, age, or improper torque — the engine loses compression, may run rough or overheat, and can suffer further internal damage if the leak is left unaddressed. Replacing the gasket promptly with the correct OEM part restores the seal and protects the engine from secondary wear.
