The Wacker Neuson Cylinder Head Complete is a genuine OEM component designed for the PT6LT and PT6LS centrifugal trash pump series as well as the RT560 and RT820 vibratory trench roller series. As a direct Wacker Neuson OEM part, the is manufactured to the exact tolerances required by the engine it serves, ensuring proper sealing, combustion chamber geometry, and coolant or oil passage alignment right out of the box. This cylinder head complete assembly is the correct replacement for equipment running the matching engine configuration across both pump and trench roller applications. Confirm your model and machine number against the fitment list before ordering to ensure an accurate match.
Key Features
- OEM Combustion Sealing Integrity — Manufactured to exact head gasket mating surface tolerances, ensuring proper compression and preventing combustion gas or coolant intrusion into the engine block.
- Complete Assembly — Supplied as a fully assembled cylinder head, simplifying installation and reducing the risk of missing valvetrain or port components during a rebuild.
- Broad Cross-Family Fitment — Fits PT6LT and PT6LS 6-inch centrifugal trash pumps (both trailer-mounted and skid-mounted configurations) as well as RT560 and RT820 vibratory trench rollers.
- Sustained Engine Output — A correctly seated cylinder head maintains rated compression, supporting full power delivery for high-demand pumping and trench compaction cycles. A warped or cracked head leads to power loss, overheating, and accelerated engine wear.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain under part number 5000154659, confirming authenticity and correct application engineering.
The cylinder head is the upper section of the engine block assembly that seals the top of each cylinder, forming the combustion chamber where air and fuel are compressed and ignited. It houses the intake and exhaust valves, valve seats, and in many configurations the coolant passages that regulate engine temperature. When a cylinder head warps, cracks, or develops a compromised sealing surface, the engine loses compression, may begin consuming coolant or oil, and will overheat under load — conditions that are especially damaging during continuous-duty applications like trash pumping or sustained trench roller operation. Replacing a failed head with the correct OEM complete assembly restores full engine integrity and protects downstream components from further damage.
