The Wacker Neuson Gear Motor is a genuine OEM Gear Motor designed for the RD40-130 and RD45-140 series tandem vibratory rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. Verified fitment spans multiple configurations across both series, including standard, canopy, open ROPS, open ROPS Stage 3, and DPF-equipped variants. If you need an exact-match replacement that drops straight into your machine, this is the correct part.
Key Features
- Genuine OEM Drive Integrity — Manufactured to the original torque output and gear ratio specifications for the RD40-130 and RD45-140 roller platforms, ensuring the drive system performs as engineered.
- Direct-Mount Replacement — Matches the original bolt pattern, shaft dimensions, and hydraulic port configuration, allowing straightforward installation without adaptation.
- Broad Series Fitment — Confirmed for RD40-130 and RD45-140 configurations including standard, canopy (c), open ROPS (o), Stage 3 open ROPS (o.3), and DPF-equipped open ROPS variants.
- Sustained Propulsion Performance — A properly functioning gear motor delivers consistent ground drive force and travel speed; a worn or failing unit causes sluggish propulsion, loss of directional control, or complete drive failure.
- Verified OEM Part Number — Part number 5100058556 is the active Wacker Neuson OEM reference, giving you confidence you are ordering the correct component for your machine.
The gear motor on a tandem vibratory roller converts hydraulic pressure from the machine's drive circuit into mechanical rotation, propelling the roller forward and in reverse. It is a core element of the ground drive system — when it operates correctly, the machine moves smoothly and responds accurately to operator inputs. When the gear motor begins to fail, symptoms typically include weak or erratic travel, unusual noise under load, or a complete loss of propulsion, all of which take the machine out of productive service until the unit is replaced.
