The Wacker Neuson 5100012302 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, this hose is manufactured to the exact dimensions and material specification of the original part, ensuring a proper seal and correct flow path within the engine cooling circuit. It covers an extensive range of configurations across the RD tandem roller family, including standard, DPF, open-ROPS, canopy, and combination drum variants. When your cooling system is due for service or a hose shows signs of wear, replacing it with part number 5100012302 keeps the repair straightforward and the machine spec-correct.
Key Features
- OEM Material and Dimensional Accuracy — Engineered to the exact inner diameter, wall thickness, and hose routing profile of the original, ensuring a leak-free connection at both couplings.
- Broad RD Series Coverage — A single part number serves RD24-100, RD28-120, RD40-130, and RD45-140 models across standard, DPF, open-ROPS, canopy, and combination configurations.
- Drop-In Replacement — Follows the original hose routing with no trimming or adaptation needed; clamp positions and end fittings match the factory assembly.
- Protects Engine Operating Temperature — A sound cooling hose maintains proper coolant flow between engine and radiator; a cracked or collapsed hose can cause overheating and unplanned shutdowns mid-compaction pass.
- Sourced Direct from Wacker Neuson — Supplied as a genuine OEM component, carrying the same part validation as the hose originally installed on the roller at the factory.
The cooling water hose carries engine coolant between the engine block, radiator, and associated cooling system components, maintaining the correct operating temperature under sustained heavy-duty compaction work. On ride-on tandem rollers like the RD series, the engine works continuously under load, making an intact cooling circuit critical to avoiding thermal damage. When a cooling hose degrades — through cracking, swelling, or collapsed walls — coolant flow is restricted or lost entirely, leading to rapid overheating and potential engine damage if the machine continues to operate.
