The Wacker Neuson Hydraulic Motor is a genuine OEM hydraulic motor designed for the RD7 series double drum rollers, including RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, and their variant configurations. Sourced directly from Wacker Neuson, this is the same component installed at the factory — ensuring a direct, confidence-first replacement when your original motor needs swapping out. Confirmed fitment spans the full RD7 family, covering LRC and HRC variants, flush-drum and padfoot configurations alike.
Key Features
- Genuine OEM Hydraulic Output: — Engineered to deliver the exact flow rate, displacement, and pressure ratings the RD7 series hydraulic circuit is built around — no calibration or compensation needed after installation.
- Direct Bolt-In Replacement: — Matches the original port configuration, shaft dimensions, and mounting interface of the factory motor, allowing a straight swap without reworking hydraulic lines or adapters.
- Broad RD7 Series Coverage: — A single part number covers RD7H, RD7Heh, RD7Hf, RD7Yeh, RD7Yehf, RD7Af, and all associated LRC, HRC, and flush/padfoot variants — confirm your model before ordering.
- Sustained Drum Drive Performance: — A properly functioning hydraulic motor maintains consistent drum speed and compaction force across varying load conditions; a worn or failing motor causes uneven drum rotation, loss of compaction output, and potential hydraulic system stress.
- Genuine Part Assurance: — Part number 5100006797 is an authorized Wacker Neuson component, traceable to the original equipment specification and backed by the manufacturer's parts program.
The hydraulic motor on an RD7 series roller is the core drive unit responsible for converting hydraulic pressure into mechanical rotation at the drum. It receives pressurized fluid from the machine's hydraulic system and uses that energy to spin the drum, propelling the roller and delivering compaction force to the surface. When this motor wears out or fails, symptoms typically include weak or unresponsive drum movement, sluggish travel, or complete loss of drive — all of which bring compaction work to a halt and can place additional strain on the hydraulic pump and circuit if left unaddressed.
