The Wacker Neuson 5100012303 is a genuine OEM Cooling Water Hose designed for the RD24, RD28, RD40, and RD45 series ride-on articulated tandem rollers. As a direct OEM replacement, part 5100012303 is sourced and manufactured to the same specifications as the original component, ensuring a correct, trouble-free installation. This hose fits an extensive range of configurations across the RD24-100, RD28-120, RD40-130, and RD45-140 model families, including standard, combination, offset drum, and DPF-equipped variants.
Key Features
- OEM-Grade Hose Construction — Manufactured to original material and pressure tolerances, ensuring the hose seats correctly against fittings without cracking, swelling, or weeping under operating temperatures.
- Direct-Fit Replacement — Engineered to match the original routing path and connection points on RD-series tandem rollers, so installation follows the same procedure as the factory hose.
- Broad RD-Series Compatibility — Confirmed fit across RD24-100, RD28-120, RD40-130, and RD45-140 models, covering standard, offset, combination, and DPF-equipped configurations.
- Sustained Cooling System Integrity — A sound cooling water hose maintains proper coolant flow to the engine; a cracked or failed hose leads to coolant loss, overheating, and unplanned machine downtime on the paving site.
- Genuine Wacker Neuson OEM Part — Carries the Wacker Neuson OEM designation, meaning it is the same part supplied through authorized dealers and factory service channels.
The cooling water hose is a critical component in the engine's liquid cooling circuit, routing coolant between the engine block, radiator, and related cooling components to regulate operating temperature. On heavy-duty ride-on tandem rollers like the RD40 and RD45, maintaining consistent coolant flow is essential for sustained high-output compaction work. When a cooling hose deteriorates — through heat cycling, age, or abrasion — it can split or collapse, starving the engine of coolant and causing rapid overheating that can result in serious engine damage if not caught quickly.
