The Wacker Neuson Drain Valve is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation with no guesswork on compatibility. This drain valve fits across a wide range of RD27 series machine numbers, making it the go-to service part for operators and technicians maintaining these walk-behind tandem rollers. Keep a verified OEM part on hand to avoid unplanned service interruptions during critical compaction work.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original valve, ensuring correct sealing performance and thread fitment within the RD27 hydraulic or fluid system.
- Broad RD27 Series Coverage — Confirmed fit across RD27-100 and RD27-120 variants, including standard hydrostatic vibratory roller and traction control configurations.
- Direct Drop-In Replacement — Matches the original port size and thread specification so the valve seats and torques correctly without modification or adapters.
- Protects Fluid System Integrity — A properly functioning drain valve allows controlled, clean fluid evacuation during service intervals; a failed or leaking valve can contaminate surrounding components and compromise hydraulic or engine fluid levels.
- Verified Part Number — Order with confidence knowing 5000174400 is the correct Wacker Neuson OEM part number for these RD27 roller models, eliminating the risk of mis-fit service parts.
A drain valve controls the release of fluid — such as engine oil, hydraulic fluid, or coolant — from a reservoir or housing during routine service or maintenance. On hydrostatic vibratory rollers like the RD27 series, proper drainage is essential to performing clean fluid changes and keeping the machine's operating systems free of contamination. When a drain valve fails, seizes, or develops a leak, it can make routine maintenance difficult and risk introducing debris or air into sensitive fluid circuits, leading to accelerated wear on hydraulic and drive components.
