The Wacker Neuson Check Valve Seal Kit is a genuine OEM replacement designed for the RD16-90, RD16-100, and CB14B series tandem rollers used in soil and asphalt compaction applications. As a direct OEM part, is manufactured to the exact material grades and dimensional tolerances required by the hydraulic check valve circuit in these machines, ensuring a proper seal without leakage or pressure loss. This kit covers multiple machine configurations across the RD16 and CB14B families, making it the correct choice whether you are servicing a standard hydrostatic roller or an IRH-equipped variant. Having the right seal kit on hand keeps your hydraulic system performing at spec and avoids the compounding damage that can result from running degraded or leaking check valve seals.
Key Features
- OEM-Grade Seal Materials — Each seal in this kit is produced to Wacker Neuson's specified elastomer compound and durometer rating for check valve service, maintaining hydraulic integrity under working pressure.
- Bolt-In Hydraulic Compatibility — Engineered to match the port geometry and seating surfaces of the check valve assembly in RD16-90, RD16-100, and CB14B rollers, so installation follows the standard service procedure without modification.
- Broad RD16 and CB14B Coverage — A single kit services multiple machine numbers across the RD16-90, RD16-100 hydrostatic, and CB14B-900/1000 configurations, consolidating your parts inventory for this roller family.
- Hydraulic Pressure Retention — Worn or cracked check valve seals allow internal bypass and pressure bleed-off, which directly degrades drive response and compaction force. Fresh seals restore full system pressure and consistent drum output.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000172855 carries the manufacturer's traceability and is the same component used in original assembly.
The check valve in a hydrostatic drive system controls the one-way flow of hydraulic fluid, preventing backflow that would cause loss of drive pressure or uncontrolled movement. On tandem rollers like the RD16 and CB14B series, maintaining a tight check valve seal is critical to consistent drum speed, braking response, and overall compaction performance. When the seals degrade, internal leakage increases, drive efficiency drops, and the hydraulic pump must work harder to compensate — accelerating wear across the entire drive circuit.
