The Wacker Neuson is a genuine OEM Cooling Water Hose designed for the RD40-130, RD45-140, and RC110 series tandem rollers and compactors. As a direct OEM part, it is manufactured to the exact specifications of the original component, ensuring a proper, trouble-free installation with no adaptation required. This hose is confirmed to fit a wide range of RD40-130 and RD45-140 variants — including C, O, and US configurations — as well as RC110 and RC110P models in standard, ROPS, and CAB configurations. Keeping this hose in good working order is essential to maintaining safe engine operating temperatures on the jobsite.
Key Features
- OEM-Grade Hose Construction — Manufactured to original pressure and temperature tolerances, ensuring the hose seats and seals correctly at both connection points without softening or cracking under sustained thermal cycling.
- Drop-In OEM Replacement — Matches the original routing, diameter, and end fittings of the factory-installed hose, allowing straightforward installation on compatible machines.
- Broad Model Coverage — Fits RD40-130 and RD45-140 series (including C, O, and US variants), plus RC110 and RC110P compactors in standard, ROPS, and CAB configurations.
- Coolant Flow Integrity — Maintains consistent coolant circulation to protect the engine from overheating during compaction work, where sustained load cycles generate significant heat.
- Sourced Direct from Wacker Neuson — Carries the genuine Wacker Neuson part number 5100012145, so you can order with confidence that you are receiving the correct OEM component.
The cooling water hose routes engine coolant between key components of the machine's liquid cooling system — typically between the engine, radiator, and associated cooling passages. By maintaining a sealed, unobstructed flow path, the hose allows the cooling system to regulate engine temperature under continuous operating loads. When a cooling hose deteriorates, develops cracks, or loses its seal at the connection points, coolant leaks out and the engine becomes vulnerable to overheating, which can result in costly thermal damage and unplanned downtime.
