Wacker Neuson 5100005723 Diesel Engine KDW 1003 US (DPU110 US)

The Wacker Neuson 5100005723 is a genuine OEM Diesel Engine KDW 1003 US (DPU110 US) designed for the DPU110 series reversible vibratory plate compactors. As a direct OEM replacement sourced through the Wacker Neuson parts program, this engine is built to the exact specifications required for the DPU110 platform, covering a wide range of Lec and Lem configuration models. Verified fitment spans DPU110Lec870, DPU110Lec970, DPU110Lem870, DPU110Lem970, DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970, and their respective US-market variants, as well as the DPU 80/110 KMAT combination machine.

Key Features

• OEM-Matched Engine Displacement and Output — Engineered to deliver the correct power curve and torque rating for the DPU110 plate compactor platform, ensuring the exciter system operates within its designed performance parameters.
• Drop-In Engine Replacement — Machined to match the existing mounting footprint, PTO interface, and fuel and exhaust connections of the DPU110 series, allowing a straightforward swap without custom fabrication.
• Broad DPU110 Series Coverage — Confirmed for Lec and Lem variants in 870 and 970 configurations, reversible (r) models, US-spec machines, and the DPU 80/110 KMAT — one part number serves the full DPU110 family.
• Sustained Compaction Force — A correctly functioning engine maintains consistent centrifugal force output through the exciter, preserving compaction depth and surface density. A worn or underpowered engine reduces plate amplitude and compaction effectiveness.
• Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson component, carrying the part number 5100005723 and meeting all original design tolerances for the KDW 1003 US engine specification.

The diesel engine is the primary power source for the DPU110 reversible vibratory plate compactor, driving the exciter unit that generates the high-frequency vibration force used to compact soil and aggregate. On reversible plate compactors, the engine must deliver stable power output across varying load conditions as the operator changes direction and travel speed — any drop in engine performance directly impacts compaction quality and production rate. When an engine reaches end-of-life or suffers internal failure, replacing it with the correct OEM unit ensures the machine returns to its rated centrifugal force output and operational characteristics.
