The Wacker Neuson Flywheel is a genuine OEM component designed for the DPU 4045H, DPU 5045H, DPU 5545H, and RD7 series machines. Sourced directly from Wacker Neuson, this flywheel meets the exact engineering standards of the original part. Fitment spans a wide range of DPU reversible vibratory plate compactors and RD7 tandem rollers, making a high-demand service item for dealers and operators running heavy compaction equipment. Confirm your model number before ordering to ensure a direct match.
Key Features
- Genuine OEM Rotational Mass Accuracy — Manufactured to the original Wacker Neuson specification, ensuring the flywheel delivers the correct rotational inertia for consistent engine starting and smooth power transfer.
- Drop-In Engine Compatibility — Engineered to match the crankshaft interface and bolt pattern of the original, allowing straightforward installation without machining or custom fitting.
- Broad DPU and RD7 Fitment — Compatible with multiple DPU 4045H, DPU 5045H, DPU 5545H, and DPU 4545H variants, as well as the RD7Heh, RD7Hehf, and RD7Hehfb tandem rollers.
- Sustained Vibration Output — A properly balanced flywheel keeps the exciter-driven compaction cycle stable; a worn or cracked flywheel can cause erratic engine behavior and reduced compaction force.
- Verified Part Number — Part number 5000226590 is cross-referenced across the full DPU 4045H through DPU 5545H model range and RD7 variants, giving you confidence you are ordering the correct replacement.
The flywheel is a heavy rotating disc mounted directly to the engine crankshaft. Its primary job is to store rotational energy between power strokes, which keeps the engine running smoothly and provides the consistent torque needed to drive the exciter mechanism in vibratory compaction equipment. On a reversible vibratory plate compactor like the DPU series, or a tandem roller like the RD7, a correctly balanced flywheel is essential for steady vibration output and reliable engine starting. When a flywheel becomes cracked, warped, or damaged at the ring gear, the engine may become difficult to start, run roughly, or fail to maintain the vibration frequency required for effective compaction.
