The Wacker Neuson Drive Pump is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. Sourced directly from Wacker Neuson, this genuine OEM Drive Pump is built to the exact design tolerances required to maintain proper hydraulic drive performance in your tandem roller. With broad coverage across the RD7 family, part number is the correct replacement for a wide range of RD7 configurations in both standard and North America-specific builds.
Key Features
- Genuine OEM Hydraulic Precision — Built to Wacker Neuson's exact flow rate and pressure specifications, ensuring the drive circuit performs as the machine was engineered to deliver.
- Direct-Fit Installation — Matches the original pump's port configuration and mounting footprint, so it connects into the RD7 hydraulic system without adaptation or modification.
- Wide RD7 Family Coverage — Compatible with RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, including both standard and North America-only configurations.
- Sustained Drive Performance — A correctly functioning drive pump maintains consistent drum speed and traction response; a worn or failing pump causes sluggish propulsion, uneven roller travel, and loss of compaction control.
- Hydraulic System Integrity — As a pressurized hydraulic component, using the correct OEM pump helps prevent seal incompatibility and pressure imbalances that can cascade into broader drivetrain damage.
The drive pump is the heart of the RD7's hydraulic propulsion system, generating the flow and pressure needed to power the drum drive motors that move the roller forward and backward. Without adequate pump output, the machine loses the ability to maintain steady travel speed and even compaction passes — critical on asphalt and soil finishing work where consistency directly affects surface quality. When the drive pump wears or fails, operators will typically notice sluggish or jerky propulsion, reduced tractive effort on grades, or a complete loss of self-propulsion, making replacement a priority to restore full operational capability.
