The Wacker Neuson 5100030401 is a genuine OEM Oil Pump designed for the DPU4545, DPU5545, and DPU6555 series reversible vibratory plate compactors, as well as the RD7 tandem roller. As a direct OEM replacement, this part is sourced and manufactured to Wacker Neuson's exact specifications, ensuring proper oil flow and pressure are maintained within the engine lubrication system. The 5100030401 covers an extensive range of DPU variants — including He, Hec, Hech, Heh, Heap, Hes, Hesh, and US-market configurations — along with select RD7 models, making it a widely applicable service part across Wacker Neuson's diesel compaction lineup.
Key Features
- Genuine OEM Lubrication Spec: — Engineered to deliver the precise flow rate and pressure the engine demands, preventing under-lubrication that leads to accelerated wear on internal components.
- Drop-In Engine Replacement: — Matches the original mounting configuration and port sizing for a straightforward installation with no rework to oil galleries or fittings.
- Broad DPU and RD7 Coverage: — Compatible with DPU4545, DPU5545, and DPU6555 reversible plate compactors across He, Hec, Hech, Heh, Heap, Hes, Hesh, and US-market variants, plus RD7 tandem roller models.
- Engine Protection: — A correctly functioning oil pump maintains continuous lubrication under load; a worn or failed pump causes oil starvation, overheating, and potential engine seizure on the compaction site.
- OEM Part Number Verified: — Sold under Wacker Neuson part number 5100030401 for confident cross-referencing against your machine's parts list.
The oil pump is responsible for drawing engine oil from the sump and circulating it under pressure through the engine's internal passages, coating bearings, cylinder walls, and other moving components to reduce friction and carry away heat. Without adequate oil pressure, metal-to-metal contact occurs rapidly, shortening engine life or causing catastrophic failure. Replacing a worn or leaking oil pump with a genuine OEM unit restores proper lubrication pressure and protects the engine investment in your compaction equipment.
