Wacker Neuson 5100024722 Diesel Engine KDW 702 3350 (DPU90)

The Wacker Neuson 5100024722 is a genuine OEM Diesel Engine KDW 702 3350 (DPU90) designed for the DPU80 and DPU90 series reversible vibratory plate compactors. As a direct OEM component sourced from Wacker Neuson, part 5100024722 is manufactured to the same specification as the engine originally fitted to these machines. Fitment covers a wide range of DPU80 and DPU90 variants — including Lec670, Lec770, Lem670, and Lem770 configurations — as well as reversible DPU80r and DPU90r models and the DPU 80/110 KMAT platform. When your compactor's power unit needs a full engine replacement, this is the correct assembly to restore full machine function.

Key Features

• Genuine OEM Engine Assembly — Sourced directly from Wacker Neuson; matched to the displacement, output, and mounting configuration specified for KDW 702 3350-equipped DPU compactors.
• Broad DPU80 and DPU90 Compatibility — Fits multiple variants across both series, including Lec670, Lec770, Lem670, Lem770, and reversible DPU80r and DPU90r configurations, plus the DPU 80/110 KMAT platform.
• Drop-In Engine Replacement — Engineered to mount directly into the existing compactor frame with correct bolt patterns, PTO interface, and fuel and electrical connections aligned to the original installation.
• Sustained Compaction Power — A correctly functioning engine delivers consistent torque to the exciter mechanism, ensuring the plate generates specified centrifugal force for proper soil and aggregate compaction. A worn or failed engine leads to reduced plate amplitude and incomplete compaction.
• US-Market Variants Supported — Part 5100024722 covers DPU90Lec770 US, DPU90rLec770 US, DPU90Lem770 US, and DPU90rLem770 US models alongside standard international configurations.

The diesel engine is the primary power source for the DPU80 and DPU90 reversible plate compactors, driving the exciter assembly that generates the high-frequency vibration needed to compact soil, gravel, and aggregate base material. Without a properly functioning engine, the compactor cannot develop the centrifugal force required to achieve adequate compaction depth or density. A failing engine — whether due to internal wear, seized components, or irreparable mechanical damage — will result in loss of plate movement, erratic compaction output, or complete machine shutdown, making a full engine replacement the correct course of action when repair is no longer viable.
