The Wacker Neuson 5100012317 Motor Gear Hub is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement, this part is sourced and specified to the exact standards set by Wacker Neuson for these machines, ensuring it installs and performs exactly as the original. Fitment covers a wide range of RD40-130 and RD45-140 configurations, including standard, combination (c), offset drum (o), and US-market variants across multiple build series.
Key Features
- Genuine OEM Torque Transmission Integrity — Manufactured to Wacker Neuson's original gear engagement and load-bearing specifications, maintaining the drive output your roller depends on under compaction loads.
- Drop-In Motor Interface Fit — Engineered to match the exact motor mounting and hub interface of the RD40-130 and RD45-140 drive systems, allowing direct installation without modification to surrounding components.
- Broad RD-Series Coverage — Confirmed fitment across RD40-130 and RD45-140 variants, including standard, combination drum, offset drum, and US-spec configurations across multiple build generations.
- Sustained Drum Drive Performance — A worn or failed motor gear hub causes slippage, uneven drum rotation, or complete loss of propulsion — replacing it restores full, consistent forward and reverse drive to the drum.
- Built for High-Cycle Compaction Duty — The gear hub operates continuously under load during every compaction pass; OEM material and heat-treatment specifications ensure it holds up through extended asphalt and soil compaction work.
The motor gear hub transfers rotational force from the hydraulic drive motor to the drum axle, converting motor output into the rolling movement that propels the machine and drives compaction. It is a critical link in the drum drive train — if the gear hub wears, cracks, or fails, the drum loses drive, resulting in loss of traction, uneven compaction, or the machine becoming unable to move under its own power. Keeping this component in good condition is essential for consistent compaction performance and safe operation of the roller on grade.
