The Wacker Neuson Cylinder Head Gasket is a genuine OEM component designed for the PT6LT and PT6LS series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this gasket is manufactured to the exact material grade and sealing tolerances required for these high-output 6-inch discharge pumps. Confirmed fitment covers the PT6LT Pump with Trailer, the PT6LS 150mm/6in Centrifugal Trash Pump Skid Mounted, and the PT6LS(I) Trash Pump. When you need a dependable, like-for-like restore of your engine's combustion seal, the is the correct part for the job.
Key Features
- OEM-Grade Combustion Sealing — Manufactured to the exact material composition and compression rating specified for the PT6LT and PT6LS engine, ensuring a gas-tight seal between the cylinder head and engine block.
- Direct Head-to-Block Fit — Engineered to the precise bolt pattern, bore diameter, and thickness of the original gasket, allowing a clean, straightforward installation without trimming or shimming.
- Confirmed PT6 Series Compatibility — Verified fitment for the PT6LT Pump with Trailer, PT6LS Skid Mounted, and PT6LS(I) Trash Pump models.
- Protects Engine Output and Prime — A properly sealed cylinder head maintains the compression needed for the engine to sustain the high-volume pumping performance these 6-inch trash pumps are built to deliver. A failed or blown gasket causes compression loss, overheating, and pump shutdown.
- Combustion Integrity Matters — A compromised head gasket can allow coolant or combustion gases to cross-contaminate, risking accelerated engine wear and unplanned downtime on water-management and dewatering operations.
The cylinder head gasket sits between the engine's cylinder head and the engine block, forming a pressure-tight seal that contains combustion gases, maintains compression, and prevents coolant or oil from entering the combustion chamber. On trash pumps like the PT6LT and PT6LS, where the engine operates under sustained load moving high volumes of water and solids, a sound head gasket is critical to keeping cylinder pressure where it needs to be. When the gasket fails — through heat cycling, age, or overtorque — compression drops, the engine loses power, runs rough, or overheats, and the pump can no longer maintain adequate flow or prime.
