Wacker Neuson 5000104430 Gear Crown

The Wacker Neuson Gear Crown is a genuine OEM component designed for RD7 series walk-behind tandem rollers and the DPU 4045H, DPU 4545, DPU 5045H, and DPU 5545 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, part number matches the original specification for a drop-in installation with no fitting adjustments. This gear crown services an exceptionally wide fitment range across both the RD7 tandem roller family and multiple DPU diesel reversible plate lines, making it a high-priority stocking part for fleet operators and dealers alike. Confirm your model number before ordering to ensure this is the correct gear crown for your machine.

Key Features

• Genuine OEM Tooth Profile: — Manufactured to the exact tooth geometry and hardness spec of the original, ensuring correct mesh engagement and load transfer within the drive train.
• Direct-Fit Installation: — Engineered to the same bore diameter, tooth count, and mounting interface as the factory part, so it seats and locks into position without modification.
• Broad Fitment Coverage: — Confirmed fit across the RD7 and RD7H tandem roller series and the DPU 4045H, DPU 4545, DPU 5045H, and DPU 5545 diesel reversible vibratory plate families.
• Sustained Drive Efficiency: — A correctly functioning gear crown maintains full torque transfer to the compaction mechanism; a worn or chipped crown causes vibration, noise, and progressive drivetrain damage.
• OEM Part Number Traceability: — Supplied under Wacker Neuson part number 5000104430, allowing straightforward cross-reference against service manuals and parts diagrams.

The gear crown is a toothed ring gear that forms a critical link in the drive transmission, transferring rotational force from the drive pinion or motor output to the compaction or propulsion system. In both vibratory plate compactors and walk-behind tandem rollers, it must sustain high cyclic loads and the constant vibration inherent to compaction work. When a gear crown wears, chips, or cracks, the result is loss of drive efficiency, irregular compaction output, audible gear noise, and — if left unaddressed — failure of surrounding drivetrain components.
