The Wacker Neuson Gear Hub Motor is a genuine OEM component designed for the RD40-130 and RD45-140 series double drum rollers, including standard, canopy, open ROPS, and DPF-equipped variants. As a direct OEM part, it is manufactured to the exact specifications required by Wacker Neuson, ensuring correct integration with the drum drive system across all covered models. This gear hub motor fits a broad range of RD-series configurations, making it the right choice whether you are servicing an RD40-130c DPF, an RD45-140o, or any of the other compatible variants in the lineup. Keep part number on hand for planned maintenance or unscheduled repairs to get your roller back to work fast.
Key Features
- Genuine OEM Torque Transmission Integrity — Manufactured to Wacker Neuson's exact gear ratio and hydraulic motor interface specifications, ensuring the drum receives the correct drive output without slippage or power loss.
- Direct Drop-In Replacement — Matches the original mounting flange, port configuration, and spline interface of the factory gear hub motor for a straightforward swap with standard tooling.
- Broad RD-Series Coverage — Compatible with RD40-130 and RD45-140 variants including standard, canopy (c), open ROPS (o), .3-revision, and DPF-equipped models — a single part number covering the full roller family.
- Sustained Drum Drive Performance — A correctly functioning gear hub motor delivers consistent drum rotation speed and compaction force; a worn or failing unit causes uneven drum movement, loss of compaction output, and increased stress on the hydraulic circuit.
- Verified Fitment Across 18 Models — Part number 5100065326 is the OEM-specified gear hub motor across all listed RD40-130 and RD45-140 configurations, eliminating guesswork when ordering for mixed fleets.
The gear hub motor is a core component of the drum drive system on a double drum roller. It converts hydraulic flow from the machine's drive circuit into mechanical rotation at the drum, providing the tractive and compaction force the machine depends on. When the gear hub motor wears or fails, symptoms typically include sluggish or uneven drum travel, loss of compaction consistency, and in severe cases a complete loss of drum drive — all of which take the machine out of productive service until the unit is replaced.
