The Wacker Neuson Cooling Water Hose is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including C and O variants across both the original and.3 generation models. Sourced directly from Wacker Neuson, this is the same part installed at the factory — ensuring a correct, trouble-free fit with no guesswork on compatibility. It fits a broad range of RD-series configurations, covering standard, combination, and oscillation roller variants. Keep this part number on hand as a planned service item to avoid unexpected cooling system issues on the job.
Key Features
- OEM Hose Construction — Manufactured to Wacker Neuson's exact material and pressure specifications for the cooling circuit, so the hose seats, seals, and flexes exactly as intended.
- Direct-Fit Replacement — Matches the original routing, end fittings, and length for the RD40-130 and RD45-140 cooling systems, connecting without modification to existing clamps and ports.
- Broad RD-Series Coverage — Compatible with RD40-130 and RD45-140 tandem rollers in standard, C (combination), and O (oscillation) configurations across both original and .3 generation platforms.
- Cooling System Integrity — A sound cooling water hose keeps coolant flowing to the engine at the correct rate; a cracked or collapsed hose leads to overheating and can cause serious engine damage during compaction work.
- Genuine Wacker Neuson Part — Part number 5100039063 is an authorized OEM replacement, giving you confidence that the part meets the same durability standard as the original fitment.
The cooling water hose carries coolant between the engine, radiator, and associated cooling circuit components, maintaining the operating temperature needed for safe, efficient engine performance. In a tandem roller working long compaction runs, the cooling system is under sustained demand — a hose that has cracked, softened, or begun to leak will cause coolant loss and rapid overheating. Replacing a worn hose promptly with the correct OEM part protects the engine and keeps the roller running at full capacity.
