The Wacker Neuson 5100026384 is a genuine OEM Cylinder Head Gasket designed for DPU80 and DPU90 series reversible vibratory plate compactors. As a direct factory replacement, this gasket delivers the exact material grade and sealing geometry required to maintain proper combustion chamber integrity across the full DPU80 and DPU90 model range, including Lec, Lem, rLec, and rLem variants. Sourcing the genuine OEM part means you get the same specification that left the factory — no guesswork on fitment or sealing performance. Confirmed compatible models include the DPU80Lec670, DPU80Lec770, DPU80Lem670, DPU80Lem770, DPU80rLec670, DPU80rLec770, DPU80rLem670, DPU80rLem770, DPU90Lec670, DPU90Lec770, DPU90Lem770, DPU90rLec770 US, DPU90rLem770 US, and US-market variants.
Key Features
- OEM Combustion Sealing Integrity — Manufactured to the exact compression rating and material grade specified for DPU-series diesel engines, ensuring a complete, leak-free seal between the cylinder head and block.
- Direct Factory Replacement — Matches the original gasket's bolt pattern, bore diameter, and layer construction for a drop-in installation with no trimming or adaptation.
- Broad DPU80 and DPU90 Compatibility — Fits Lec, Lem, rLec, and rLem engine configurations across both the 670 and 770 machine series, including US-market variants.
- Compression and Power Retention — A failed or compressed head gasket causes loss of cylinder pressure, rough running, and overheating. Replacing with the correct OEM gasket restores full engine output and keeps your compactor working at rated force.
- Fuel and Coolant Pathway Integrity — The gasket seals oil and fuel passages as well as the combustion chamber, making material grade critical — the genuine OEM specification prevents cross-contamination between engine circuits.
The cylinder head gasket forms the critical seal between the engine's cylinder head and the engine block, containing combustion pressure while simultaneously sealing oil and fuel passages that pass through the head joint. On DPU-series diesel plate compactors, this gasket operates under sustained high-compression cycling and elevated temperatures generated during heavy compaction work. When a head gasket fails — through age, overheating, or improper torque — combustion pressure escapes, engine efficiency drops sharply, and internal fluids can migrate where they should not, leading to accelerated engine wear. Replacing the gasket promptly with the correct OEM part is one of the most cost-effective ways to protect the engine from secondary damage.
