The Wacker Neuson is a genuine OEM Hydraulic Tank Cap designed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this cap meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement that installs in the same position and manner as the part it replaces, requiring no adaptation. If your RD11 series roller is showing signs of hydraulic fluid contamination or a damaged, missing, or improperly sealing tank cap, the is the correct OEM replacement to restore proper system integrity.
Key Features
- OEM-Grade Seal Integrity — Manufactured to the original pressure and material specification, ensuring the cap seats and seals correctly on the hydraulic reservoir to prevent contamination and fluid loss.
- Direct-Fit Replacement — Matches the original thread pattern and cap interface on RD11 series rollers, dropping in exactly where the factory cap was installed.
- RD11 Series Compatibility — Verified fitment for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers — three distinct configurations of the RD11 platform.
- Protects Hydraulic System Cleanliness — A correctly sealing tank cap keeps moisture, dirt, and debris out of the hydraulic fluid, which directly affects the performance and longevity of the hydrostatic drive and vibration systems.
- Fuel and Fluid System Safety — A failed or missing hydraulic tank cap on a pressurized system can result in fluid leaks and contamination hazards; replacing it promptly with a genuine OEM part maintains safe operating conditions.
The hydraulic tank cap seals the opening of the hydraulic fluid reservoir, keeping the system closed to outside contaminants such as dirt, dust, and moisture while allowing the tank to breathe or vent as designed. On a hydrostatic double drum vibratory roller like the RD11 series, the hydraulic system powers both the drive and the drum vibration functions, meaning clean, uncontaminated fluid is critical to consistent compaction output and machine control. When the cap is cracked, missing, or no longer sealing properly, hydraulic fluid can become contaminated or leak, leading to degraded system performance and potential damage to pumps, motors, and valves.
