The Wacker Neuson is a genuine OEM Spray Bar Complete designed for the RD7 series tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original part installed at the factory, ensuring a consistent, drop-in fit across the full range of compatible RD7 walk-behind and tandem roller configurations. Sourced directly through authorized Wacker Neuson supply channels, part number is the correct, verified replacement to specify when servicing any of these machines. Keep your roller's water distribution system operating as intended by using the right part from the start.
Key Features
- OEM-Grade Water Distribution: — Manufactured to the same flow-path and nozzle specifications as the original assembly, ensuring consistent drum-surface wetting across the full width of the roller pass.
- Complete Assembly Replacement: — Supplied as a complete spray bar unit, allowing straightforward swap-out rather than sourcing individual components separately.
- Broad RD7 Series Coverage: — Confirmed fitment across RD7A, RD7H, RD7He, and RD7Ye tandem rollers and walk-behind roller variants, covering a wide range of serial configurations within the RD7 family.
- Consistent Drum Moisture Control: — A properly functioning spray bar keeps asphalt and material from sticking to the drums during compaction; a worn or blocked assembly leads to uneven wetting, surface pickup, and poor compaction quality.
- Verified OEM Part Number: — Cross-referenced as Wacker Neuson part 5100028105, eliminating guesswork when ordering and reducing the risk of receiving an incompatible substitute.
The spray bar on a tandem roller delivers a controlled flow of water across the width of each compaction drum to prevent asphalt or material buildup during operation. By keeping the drum surface evenly moistened, it ensures clean contact with the mat and consistent compaction results pass after pass. When the spray bar becomes clogged, cracked, or damaged, water distribution becomes uneven or fails entirely, leading to material adhesion on the drum, surface defects in the finished mat, and potential rework on the job.
