The Wacker Neuson 5100028105 is a genuine OEM Spray Bar Complete designed for the RD7 series walk-behind tandem rollers, covering the RD7A, RD7H, RD7He, and RD7Ye model variants. Sourced directly from Wacker Neuson, this assembly matches the original component specification and drops into place without modification to the water system plumbing. The 5100028105 is the correct OEM choice for operators maintaining drum wetting performance on their RD7 series roller fleet.
Key Features
- Full OEM Water Distribution Coverage — Genuine Wacker Neuson construction ensures correct nozzle spacing and flow distribution across both drum surfaces, maintaining the water film that prevents asphalt pickup.
- Complete Assembly Replacement — Supplied as a Spray Bar Complete, this unit replaces the entire bar assembly in a single service operation, eliminating the need to source individual nozzles or fittings separately.
- Broad RD7 Series Compatibility — Confirmed fitment across multiple RD7, RD7A, RD7H, RD7He, and RD7Ye tandem roller configurations, covering both North American and standard variants.
- Consistent Drum Wetting for Asphalt Work — A functioning spray bar delivers an even water mist across the compaction drums; a clogged or damaged bar leads to asphalt material sticking to the drum surface, compromising mat quality and finish.
- Direct OEM Sourcing — Carrying Wacker Neuson part number 5100028105, this is the same component supplied through authorized Wacker Neuson dealer channels, with no substitutions or compromises to the original design.
The spray bar on a walk-behind tandem roller is responsible for distributing a controlled water mist evenly across the steel drums during asphalt compaction passes. This water film prevents hot asphalt mix from bonding to the drum surface, which would otherwise cause tearing and surface defects in the mat. When the spray bar becomes clogged, cracked, or fails to distribute water uniformly, drum pickup increases rapidly — degrading finish quality and forcing the crew to halt compaction until the issue is resolved.
