The Wacker Neuson 5100042194 is a genuine OEM Cylinder Head Gasket designed for the RTLx-SC3 and RTx-SC2 remote-controlled trench rollers, as well as the DPU110 series reversible vibratory plate compactors. As a direct OEM part, the 5100042194 is manufactured to the exact material grade and sealing specification required by the original engine assembly, ensuring a proper combustion seal from the first startup. This gasket fits an extensive range of RTLx-SC3 trench roller configurations — including Compatec-equipped variants — and covers the full DPU110 plate compactor lineup, spanning Lec, Lem, Lekc, rLec, and rLem engine variants in both standard and US-spec configurations.
Key Features
- Combustion-Rated OEM Sealing Material — Manufactured to the original compression and temperature tolerances required by the engine, maintaining a leak-free combustion chamber seal under sustained working loads.
- Drop-In Engine Deck Replacement — Matches the original head bolt pattern and bore diameter exactly, seating correctly between the cylinder head and engine block without trimming or modification.
- Broad Fitment Across Two Machine Families — Compatible with RTLx-SC3 and RTx-SC2 trench rollers and the full DPU110 reversible plate compactor range, including Lec, Lem, Lekc, rLec, and rLem engine configurations in standard and US-spec builds.
- Protects Engine Integrity Under Compaction Loads — A sound head gasket maintains cylinder compression and prevents coolant or oil ingestion into the combustion chamber; a failed gasket leads to power loss, overheating, and accelerated engine wear on the job.
- Fuel and Combustion System Safety — A correctly seated head gasket is critical to preventing combustion gas blowby, which can cause uncontrolled pressure buildup and fuel contamination — making gasket condition a genuine safety consideration during engine service.
The cylinder head gasket forms a critical pressure seal between the engine's cylinder head and the engine block. It contains combustion gases within the cylinder during each power stroke, maintaining the compression needed for efficient ignition and full engine output. When a head gasket fails — through heat stress, improper torque, or age — the engine loses compression, oil and coolant can mix, and the machine will overheat or run rough; in severe cases, continued operation causes irreversible internal engine damage. Replacing the gasket with a correctly spec'd OEM part like the 5100042194 restores the combustion seal and protects the engine investment in your compactor or trench roller.
