The Wacker Neuson 5100031503 is a genuine OEM Diesel Engine designed for the DPU4545HEH US, DPU5545HEH US, DPU5545HECH US, and DPU4545HECH US reversible vibratory plate compactors. As a factory-sourced component, it is built to the exact tolerances and output specifications required to restore full compaction performance to your machine. Verified fitment across the DPU4545 and DPU5545 series means no guesswork when sourcing a direct engine replacement. If your reversible plate compactor has suffered engine failure or irreparable internal damage, part number 5100031503 is the correct OEM solution to get your equipment back to work.
Key Features
- Genuine OEM Power Output Match — Sourced directly from Wacker Neuson, this diesel engine delivers the exact displacement, torque curve, and RPM range required to drive the exciter assembly on DPU4545 and DPU5545 series compactors.
- Drop-In Engine Replacement — Engineered to align with the original mounting points, fuel connections, and drive interfaces on the host machine, making engine changeover straightforward for qualified technicians.
- Confirmed Fitment Across Four Models — Verified for the DPU4545HEH US, DPU5545HEH US, DPU5545HECH US, and DPU4545HECH US reversible plate compactors, covering both standard and electric-clutch variants in the HEH and HECH lines.
- Restored Compaction Force — A properly functioning engine sustains the plate speed and centrifugal force needed for effective soil and aggregate compaction in both forward and reverse passes; a failing engine causes under-compaction and uneven results.
- Fuel System Integrity — As the primary power source and fuel-consuming component, OEM specification ensures correct fuel delivery compatibility and emission compliance for the machine's original design intent.
The diesel engine is the core power unit of a reversible vibratory plate compactor, converting fuel combustion into rotational energy that drives the exciter mechanism and generates the compaction force transmitted through the base plate. Without a correctly functioning engine, the plate cannot maintain the speed or amplitude needed to consolidate soil, aggregate, or granular sub-base material. Engine wear, seizure, or catastrophic failure will bring compaction work to a complete stop, making accurate engine replacement one of the most critical service interventions for this class of equipment.
