The Wacker Neuson Hydraulic Tank is a genuine OEM Hydraulic Tank designed for the RD7A, RD7H, and RD7He series tandem rollers. As a direct Wacker Neuson OEM part, it is manufactured to the same standards as the original component that left the factory, ensuring a correct, hassle-free installation. Verified fitment spans multiple build variants across the RD7 tandem roller family, including walk-behind roller configurations, making a dependable choice when restoring your machine to full working condition.
Key Features
- OEM-Grade Construction — Built to the same material and dimensional specifications as the original tank, ensuring correct fluid capacity, port alignment, and sealing surface integrity for hydraulic system reliability.
- Drop-In Installation — Engineered to match original mounting points, port locations, and hardware interfaces on RD7-series rollers, so the tank seats and seals correctly without fabrication or adaptation.
- Broad RD7 Series Coverage — Confirmed fitment across RD7A, RD7H, and RD7He variants, including tandem roller, walk-behind roller, and North America-specific RD7He configurations.
- Sustained Hydraulic System Performance — A properly functioning hydraulic tank maintains consistent fluid supply and temperature control for the drum drive and vibration circuits; a cracked or degraded tank leads to fluid loss, overheating, and loss of compaction force.
- Hydraulic Fluid Integrity — The sealed OEM tank design helps prevent contamination ingress — a critical factor for protecting hydraulic pumps, valves, and motors downstream from particulate damage.
The hydraulic tank stores and supplies fluid to the roller's hydraulic system, which powers drum propulsion, vibration, and steering functions. It also acts as a reservoir that allows the fluid to dissipate heat and release entrained air before returning to the pump. When the tank is cracked, leaking, or internally corroded, fluid levels drop, the system runs hot, and critical hydraulic components are starved of the clean, pressurized supply they need — leading to sluggish or failed drum operation on the job.
