Wacker Neuson 5100024723 Diesel Engine KDW 702 3350 U S (DPU90 US)

The Wacker Neuson is a genuine OEM Diesel Engine KDW 702 3350 U S (DPU90 US) designed for DPU80 and DPU90 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this engine assembly carries the same part number and specification as the original unit installed at the factory. It is confirmed compatible across a broad range of DPU80 and DPU90 Lec, Lem, rLec, and rLem variants, including US-market configurations. Whether you are performing a full engine swap on a high-hour machine or replacing a failed unit, part number ensures you are installing an assembly built to the same specification as the original.

Key Features

• Genuine OEM Engine Assembly — Manufactured to Wacker Neuson's original design specification for the KDW 702 powerplant, ensuring correct displacement, output rating, and mounting geometry for the DPU80/DPU90 platform.
• Direct Drop-In Replacement — Engine mounts, shaft dimensions, and ancillary connection points match the original layout, allowing the assembly to seat and connect without modification to the compactor frame or drive system.
• Broad DPU80 and DPU90 Fitment — Verified for DPU80Lec, DPU80Lem, DPU80rLec, DPU80rLem, DPU90Lec, DPU90Lem, DPU90rLec, and DPU90rLem variants, including 670, 770, and US-spec configurations.
• Restores Full Compaction Output — A correctly functioning engine delivers the consistent power needed to drive the exciter mechanism at rated speed; a worn or failed engine results in reduced centrifugal force, uneven compaction, and failure to meet compaction depth specs on soil and aggregate.
• Emissions and Fuel System Compliance — As a genuine OEM unit, the KDW 702 assembly meets the emissions and fuel system requirements applicable to the DPU90 US market configuration, keeping your machine in regulatory compliance on regulated jobsites.

The diesel engine is the primary power source for the DPU80 and DPU90 reversible vibratory plate compactors, driving the hydraulic exciter system that generates the high-frequency vibration used to compact soil, aggregate, and granular base material. When the engine produces insufficient power — due to wear, internal failure, or damage — the exciter cannot reach its rated operating speed, which directly reduces compaction force and leads to inadequate density results in the field. Replacing a failed engine with the correct OEM assembly, part number 5100024723, restores the machine to its rated compaction performance and ensures the drive system operates within its designed load parameters.
