The Wacker Neuson Hydraulic Tank is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES, RD7H-S, and RD7-RAW variants. As a direct factory replacement, this tank is built to exact specifications and integrates seamlessly with the hydraulic system on your RD7 roller. Whether you're running the EU-spec RD7H-ES or the standard RD7H-S double drum roller, part is the correct OEM replacement to restore your machine to full operating condition.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact material and capacity specifications for the RD7 hydraulic circuit, ensuring proper fluid volume and pressure retention.
- Direct Bolt-On Replacement: — Engineered to match the original mounting points and port locations on RD7 series tandem rollers, so installation follows the same procedure as the factory-fitted unit.
- Broad RD7 Series Coverage: — Confirmed fitment across multiple RD7 configurations, including RD7H-ES, RD7H-S, EU-spec variants, and RD7-RAW double drum roller builds.
- Protects Hydraulic System Integrity: — A properly sealed, undamaged hydraulic tank maintains correct fluid levels and prevents contamination — critical for consistent drum drive and steering response on asphalt compaction passes.
- Leak-Free Fluid Retention: — A cracked or compromised hydraulic tank leads to fluid loss, overheating, and loss of drive pressure. Replacing it promptly with the correct OEM unit keeps your hydraulic system operating within designed parameters.
The hydraulic tank on an RD7 tandem roller serves as the reservoir for the hydraulic fluid that powers the drum drives, steering, and other hydraulic functions across the machine. It stores and conditions the fluid between cycles, allowing heat to dissipate and air to separate before fluid re-enters the system. When the tank cracks, leaks, or becomes contaminated, hydraulic pressure drops, drum drive performance becomes inconsistent, and the risk of pump damage increases significantly — making timely replacement essential to protecting the rest of the hydraulic circuit.
