The Wacker Neuson Water Tank Rd27 is a genuine OEM component designed for the RD27-100 and RD27-120 series ride-on tandem rollers. Sourced directly from Wacker Neuson, this tank is an exact match for the original unit installed on RD27 Pro, RD27 Basic, and standard RD27 configurations across multiple production runs. It fits the full range of RD27-100 and RD27-120 machines, including Tier 4 Final variants, ensuring verified compatibility whether you're servicing a Pro T4F or a Basic T4F roller. Drop-in installation means no fabrication or adaptation work — the tank seats and connects exactly as the original did.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the tank holds the correct volume and resists cracking under the vibration loads typical of tandem roller operation.
- Direct-Fit Replacement — Engineered to mount in the same position and connect to the same lines as the factory unit, with matching port locations and bracket points for straightforward installation.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 tandem rollers across multiple machine numbers, including RD27 Pro, RD27 Basic, and Tier 4 Final variants.
- Sustained Drum Wetting Performance — A properly functioning water tank keeps drums consistently wetted during asphalt compaction passes, preventing material pickup and maintaining a clean, even finish across the mat.
- Verified Part Number Fit — Part number 5200002922 is confirmed against Wacker Neuson's parts documentation for the RD27 platform, so you can order with confidence that this is the correct tank for your machine.
The water tank on the RD27 tandem roller supplies the drum wetting system, which continuously coats the steel drums with a fine film of water during asphalt rolling passes. This prevents hot asphalt from sticking to the drum surface — a condition that causes tearing, uneven compaction, and a compromised mat finish. When the tank cracks, leaks, or fails to hold volume, the wetting system loses pressure and flow, leaving the drums dry and creating adhesion problems almost immediately. Replacing a damaged tank promptly restores consistent water delivery and protects both the finished surface and the drums themselves from unnecessary wear.
