The Wacker Neuson is a genuine OEM Relief Valve Seal Kit designed for the RD16-90, RD16-100, and CB14B series tandem rollers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, every seal in this kit meets the original design specifications for material grade and dimensional tolerancing. This kit covers multiple machine configurations across the RD16 and CB14B families, including hydrostatic and standard vibratory roller variants used in soil and asphalt compaction applications. Verifying your machine number against the fitment list before ordering ensures a correct, confident installation.
Key Features
- OEM-Grade Seal Material: — Each seal is manufactured to the original compound and compression specification, maintaining consistent hydraulic pressure at the relief valve seat across operating temperatures.
- Complete Kit Configuration: — All seals required for a full relief valve service are included in a single kit, eliminating the need to source individual components separately.
- Broad RD16 and CB14B Fitment: — Engineered to fit RD16-90, RD16-100, and CB14B-900/CB14B-1000 tandem rollers, covering both hydrostatic and standard vibratory configurations used in soil and asphalt compaction.
- Hydraulic System Integrity: — A correctly sealed relief valve maintains precise system pressure, allowing the roller's drive and vibration circuits to perform as designed. Worn or failed seals cause pressure bleed-off, sluggish response, and uneven compaction output.
- Fuel and Fluid Safety Compliance: — Hydraulic seal condition is critical to preventing fluid leaks at pressure points; using OEM-specification seals helps ensure the machine operates within its designed pressure envelope and reduces the risk of uncontrolled hydraulic discharge.
The relief valve seal kit services the hydraulic relief valve, which acts as a pressure safety mechanism within the roller's hydraulic circuit. Its role is to limit system pressure to a safe operating threshold, opening to divert flow when pressure exceeds the set point and protecting downstream components from damage. When the seals inside the relief valve degrade, the valve can leak internally, causing the system to bleed pressure continuously — resulting in reduced drive force, inconsistent drum vibration, and potential overheating of the hydraulic fluid. Replacing the seals with part 5000172856 restores a tight, leak-free seat and returns the hydraulic system to its intended operating pressure.
