The Wacker Neuson Fly Wheel is a genuine OEM component designed for the DPU6555Heh US, DPU6555Hech US, DPU5545Heh US, DPU5260Hehb+ US, and DPU6275Hehb+ US series plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring a correct, hassle-free installation. Sourced directly through authorized Wacker Neuson supply channels, this fly wheel is the right choice when you need a confirmed match for your machine.
Key Features
- OEM-Matched Mass and Balance — Manufactured to the precise rotational inertia specification of the original, so engine smoothing and power delivery behave exactly as intended from day one.
- Direct-Mount Installation — Engineered to align with the original crankshaft taper, keyway, and bolt pattern, so the 5100069039 seats and torques correctly without rework or adaptation.
- Confirmed Fitment Across Five Models — Verified for DPU6555Heh US, DPU6555Hech US, DPU5545Heh US, DPU5260Hehb+ US, and DPU6275Hehb+ US plate compactors — use your model number to confirm before ordering.
- Sustained Compaction Power — A correctly functioning fly wheel maintains consistent engine rpm under load, which is critical for delivering even compaction force cycle after cycle on demanding subbase and asphalt work.
- Genuine Wacker Neuson OEM Part — Carries the full Wacker Neuson OEM designation, giving fleet managers and service technicians confidence in part origin and traceability.
The fly wheel is a heavy rotating disc mounted directly to the engine crankshaft. Its primary job is to store rotational energy between combustion strokes, smoothing out the natural pulses of a single-cylinder engine and keeping the crankshaft turning at a consistent speed under varying loads. On a plate compactor like the DPU series, this steady output translates directly into consistent eccentric-shaft speed and, in turn, predictable compaction force at the plate. When a fly wheel cracks, becomes unbalanced, or develops damaged keyway seats, the engine will run rough, vibration patterns become erratic, and compaction quality drops — issues that typically worsen quickly if the machine continues to run.
