Wacker Neuson 5100005722 Diesel Engine KDW 1003 (DPU110)

The Wacker Neuson 5100005722 is a genuine OEM Diesel Engine KDW 1003 (DPU110) designed for the DPU110 series reversible vibratory plate compactors. As a direct OEM engine assembly, part number 5100005722 is sourced and supplied to the exact specifications Wacker Neuson builds into these machines, ensuring compatibility across the full DPU110 and DPU110r model range including Lec and Lem variants. This engine assembly covers both standard and US-market configurations, making it the definitive replacement for operators running DPU110-series equipment. Confirm your model number against the fitment list before ordering to ensure correct application.

Key Features

• Genuine OEM Engine Assembly — Supplied to Wacker Neuson's exact displacement, output, and emissions calibration for the KDW 1003 powerplant, so the engine performs as the machine was originally rated.
• Broad DPU110 Series Coverage — Fits DPU110Lec, DPU110Lem, DPU110rLec, and DPU110rLem variants across both 870 and 970 build levels, including US-market editions.
• Drop-In Engine Replacement — Engineered to match the original mounting footprint, fuel, and electrical connections of the DPU110 platform, supporting a straightforward swap without adapting brackets or hardware.
• Sustained Compaction Output — A correctly functioning KDW 1003 engine delivers consistent centrifugal force to the exciter, maintaining the plate's compaction capacity on soil and aggregate applications. A worn or seized engine directly compromises compaction depth and production rate.
• Fuel System Integrity — As a diesel-powered assembly, correct engine specification is critical to fuel delivery, injection timing, and safe operation — using the verified OEM unit eliminates guesswork on these parameters.

The KDW 1003 is the diesel engine that powers the DPU110 reversible vibratory plate compactor's exciter system, converting fuel combustion into the rotational force that drives the eccentric weights and generates compaction energy at the baseplate. On reversible DPU models, the engine also supports directional control of the plate through the drive system, making its condition directly linked to both productivity and maneuverability on site. When the engine loses compression, develops fuel delivery faults, or fails entirely, the plate compactor cannot generate adequate centrifugal force — resulting in under-compaction of the subbase and costly rework.
