The Wacker Neuson Diesel Motor 1D81S-319 is a genuine OEM power unit designed for the DPU 6555Hec reversible vibratory plate compactor. As a factory-sourced component, is manufactured to the exact specifications required by the DPU 6555Hec, ensuring a direct, correct-fit installation with no guesswork. This is the same motor supplied by Wacker Neuson during original equipment assembly, giving you confidence that the part will perform exactly as the machine was engineered to deliver. If your DPU 6555Hec has lost power, is running rough, or has suffered engine failure, this genuine OEM replacement restores the unit to full operational condition.
Key Features
- Genuine OEM Engine Integrity — Sourced directly from Wacker Neuson, this motor meets the precise displacement, output, and mounting specifications of the original 1D81S-319 unit — not a generic approximation.
- Direct-Fit Replacement for DPU 6555Hec — Engineered specifically for the DPU 6555Hec reversible vibratory plate, this motor bolts into the existing mounting configuration using the original hardware and connections.
- Full Compaction Power Restored — The diesel motor drives the exciter mechanism that generates compaction force; a worn or seized engine means zero plate output. Replacing with 5100004235 brings the machine back to its rated compaction performance.
- Heavy-Duty Diesel Durability — Built for the demands of reversible plate compaction work — extended run times, variable load cycles, and tough site conditions — this motor is rated for the operational profile of the DPU 6555Hec.
- Fuel System Compatibility — As a genuine OEM diesel motor, fuel delivery, governor settings, and emission compliance are matched to the DPU 6555Hec's original design — important for both performance and regulatory compliance on the job.
The diesel motor is the primary power source of the DPU 6555Hec reversible vibratory plate compactor, converting fuel energy into rotational output that drives the exciter assembly and produces the compaction force at the plate. On a reversible DPU model, the engine must deliver consistent torque across both forward and reverse travel directions, making engine condition critical to productive operation. When the motor wears out, loses compression, or fails entirely, the machine cannot generate the centrifugal force needed to compact soil or aggregate — bringing work to a complete stop until the unit is replaced.
