The Wacker Neuson Motor Hatz 1D42S Electric is a genuine OEM power unit designed for the DPU 4045H, DPU 5045H, DPU 4545He, DPU 5545He, and related DPU series diesel vibratory plates. As a direct Wacker Neuson OEM assembly, part is manufactured to the exact output and interface specifications of the original unit — ensuring it drops into your machine the way the factory intended. This motor is confirmed for an extensive range of DPU 4045, DPU 4545, DPU 5045, and DPU 5545 variants, including Heap, Hech, and US-market configurations. When you need to restore full compaction power to your plate, sourcing the correct OEM assembly is the straightforward path to getting back to work.
Key Features
- Genuine OEM Power Output: — Matched to the original Hatz 1D42S single-cylinder diesel specification, ensuring correct torque delivery and governor response for vibratory plate compaction work.
- Electric-Start Configuration: — Built with the integrated electric start system, allowing direct swap of the complete motor assembly without retrofitting a manual recoil arrangement.
- Broad DPU Series Compatibility: — Confirmed fitment across DPU 4045H, DPU 5045H, DPU 4545He/Heh/Hech, DPU 5545He/Heh/Hech, and US-market variants, covering a wide span of Wacker Neuson diesel vibratory plate generations.
- Complete Engine Assembly: — Supplied as a complete motor unit, so installation does not require sourcing individual sub-components or adapting mismatched hardware.
- Fuel System Integrity: — As a genuine OEM assembly, the fuel and electrical interfaces are correct for each listed DPU model, reducing the risk of fuel delivery or ignition issues that can arise from incompatible replacement engines.
- Verified Part Number: — Wacker Neuson part 5000220375 is the OEM-listed motor assembly for all machine numbers referenced across the DPU 4045, 4545, 5045, and 5545 He/H series.
The Hatz 1D42S is a compact single-cylinder diesel engine that powers the exciter mechanism on Wacker Neuson DPU series vibratory plates, generating the rotational force needed to drive the eccentric weight assembly and produce compaction vibration. When this motor runs correctly, the plate delivers consistent centrifugal force across the compaction surface — critical for achieving proper soil or base material density. A failing or seized motor results in complete loss of compaction capability, and because the engine drives the exciter directly, there is no production workaround; the motor must be in service for the machine to function.
