The Wacker Neuson Crankcase is a genuine OEM crankcase designed for the DPU4545, DPU5545, DPU6555, and DPU6055 series reversible vibratory plate compactors. As a direct factory replacement, this part is manufactured to the same standards as the original, ensuring a correct fit within the engine assembly. Fitment covers an extensive range of DPU variants including He, Heh, Hec, Hech, Heap, Hesh, Hecsh, and related US and special-configuration models across all four series.
Key Features
- OEM Structural Integrity — Cast and machined to the same dimensional tolerances as the original, maintaining correct bearing bore alignment and oil gallery geometry critical for this engine family.
- Drop-In Engine Fit — Engineered to align directly with the existing mounting points, sealing surfaces, and internal components of the DPU series engine without rework or modification to mating parts.
- Broad DPU Series Coverage — Confirmed fitment across DPU4545, DPU5545, DPU6555, and DPU6055 reversible vibratory plate compactors, covering He, Heh, Hec, Hech, Heap, and related configuration variants.
- Sustained Compaction Output — A sound crankcase maintains proper lubrication containment and crankshaft support, allowing the engine to deliver consistent centrifugal force output to the exciter unit during heavy soil and aggregate compaction work.
- Oil Containment Reliability — Proper crankcase sealing surfaces prevent oil leaks that would otherwise lead to lubrication starvation, accelerated internal wear, and unplanned engine failure in the field.
The crankcase is the main structural housing of the engine — it encloses the crankshaft, supports the cylinder assembly, and contains the engine oil that lubricates all moving internal components. On reversible vibratory plate compactors like the DPU series, the engine operates under continuous load and vibration, placing sustained stress on the crankcase structure and its sealing surfaces. A cracked, warped, or worn crankcase allows oil to escape, disrupts bearing support, and can lead to catastrophic engine failure if left unaddressed. Replacing a damaged crankcase with a genuine OEM unit restores the correct structural foundation of the engine and protects all internal components.
