The Wacker Neuson 5100011961 is a genuine OEM Driving Gear designed for the RC50, RC50p, and RD18 series compaction equipment. As a direct factory replacement, this part is manufactured to the same specifications as the original component installed at the factory, ensuring consistent engagement and power transfer within the drivetrain. This gear fits an extensive range of RC50 and RD18 configurations, including CAB, ROPS, DPF, SE, and US variants, as well as the full RD18-80, RD18-100, and RD18-100c model lines. Confirm your machine's model number before ordering to ensure compatibility with your specific serial range.
Key Features
- Genuine OEM Tooth Geometry — Manufactured to exact tooth profile and hardness specifications, maintaining proper mesh and load distribution in the drivetrain.
- Direct Drop-In Replacement — Engineered to the same dimensions as the original gear, allowing installation without shaft modification or custom fitting.
- Broad RC50 and RD18 Coverage — Compatible with RC50, RC50p, RC50 DPF, RC50 ROPS, RC50 CAB, RD18-80, RD18-100, RD18-100c, and their US and SE variants.
- Sustained Drive Efficiency — A worn or chipped driving gear causes slippage, vibration, and uneven drum rotation; this replacement restores full power delivery to the compaction drum.
- Single-Drum and Tandem Roller Compatibility — Spans both the RC50 single-drum soil compactor family and the RD18 tandem roller series, making it a versatile stock item for mixed fleets.
The driving gear is a core drivetrain component responsible for transmitting rotational force from the machine's power source to the drum or drive system. It meshes with mating gears to maintain the correct speed and torque ratio needed for consistent drum rotation and forward propulsion during compaction passes. When the driving gear wears, chips, or fails, the operator may notice irregular drum movement, unusual noise from the drivetrain, or a loss of traction and compaction force — all of which compromise surface quality and machine reliability.
