The Wacker Neuson 5100011704 Carrier Star is a genuine OEM component designed for the RD24-100, RD27-120, and RD28-120 series tandem rollers. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring proper fit within the drum drive assembly. It covers the full RD24 and RD28 model range, including standard, combination, and oscillation variants across US and international configurations.
Key Features
- Genuine OEM Precision Engineering — Manufactured to exact tolerances for the carrier star's load-bearing and torque-transfer role, so gear mesh alignment stays consistent under compaction stress.
- Direct Drum Drive Replacement — Drops into the planetary drive assembly with no adaptation, restoring the original power transfer path between the motor and drum.
- Broad RD Series Compatibility — Fits the RD24-100, RD27-120, and RD28-120 families, including standard, combination (c), and oscillation (o) configurations in both US and international variants.
- Sustained Compaction Output — A worn or damaged carrier star causes uneven drum rotation and loss of drive force; replacing it restores consistent roller speed and compaction pass quality on asphalt and soil surfaces.
- Verified Wacker Neuson Part Number — Part number 5100011704 cross-references directly to all listed RD24, RD27, and RD28 machine numbers, giving you confidence before you order.
The carrier star is a core element of the planetary gear set that drives the roller drum. It meshes with the planet gears and transmits torque from the hydraulic drive motor to the drum, controlling rotational speed and compaction force delivery. When a carrier star wears, cracks, or loses teeth, drive power becomes erratic, drum speed fluctuates, and the roller may lose traction or cease to propel correctly — conditions that halt production and can cause uneven mat density on asphalt paving projects. Replacing the carrier star with a genuine Wacker Neuson part restores the drivetrain to its original mechanical integrity.
