The Wacker Neuson Motor Hatz 1D42S is a genuine OEM diesel engine assembly designed for the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H series vibratory plates. Sourced directly from Wacker Neuson, this is the exact motor specified for these machines — no substitutions, no guesswork. The covers multiple DPU plate compactor variants including the DPU 4045Hap and DPU 5545H, making it the correct replacement across a broad range of the DPU H-series lineup.
Key Features
- OEM-Matched Engine Output: — Built to the same power and torque specifications as the original Hatz 1D42S, ensuring the plate compactor delivers full centrifugal force and operating performance from the first start.
- Direct-Mount Replacement: — Engineered to bolt directly into the DPU H-series frame using the original mounting points, so installation follows the standard service procedure without custom adapters.
- Broad DPU H-Series Coverage: — Fits DPU 4045H, DPU 4045Hap, DPU 4545H, DPU 4545Hap, DPU 5045H, and DPU 5545H vibratory plate compactors in a single part number.
- Sustained Compaction Power: — A correctly functioning Hatz 1D42S keeps exciter-driven compaction force consistent across the full working cycle; a worn or failed engine causes loss of plate frequency and poor compaction results.
- Fuel System Integrity: — As a genuine OEM engine assembly, the 5000220338 includes components sized and sealed to Wacker Neuson's fuel and emissions requirements, supporting compliant operation in the field.
The Hatz 1D42S is a single-cylinder, air-cooled diesel engine that serves as the primary power source for the DPU H-series vibratory plate compactors. It drives the exciter unit that generates the compaction force needed to consolidate soil, gravel, and asphalt sub-bases. When the engine loses compression, fails to start, or delivers inconsistent power, the plate can no longer maintain the required vibration frequency — leading to uneven compaction, project delays, and potential re-work. Replacing the motor with the correct OEM unit restores the machine to its original operating specification.
