The Wacker Neuson 5100023306 Water Oil Cooler is a genuine OEM component designed for RC50 and RC70 series single-drum soil compactors. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring proper thermal performance and system compatibility. It fits across multiple RC50 and RC70 configurations, including padfoot and smooth-drum variants in both standard and US-market builds. Always confirm your machine's serial number against the fitment list before ordering.
Key Features
- Genuine OEM Thermal Specification: — Engineered to maintain the precise heat-exchange capacity required for the RC50 and RC70 hydraulic and engine systems — not a generic approximation.
- Drop-In OEM Replacement: — Matches the original mounting points, port sizing, and connection interfaces of the factory-installed cooler for a straightforward installation.
- Broad RC-Series Coverage: — Confirmed fitment across RC50, RC50p, RC70, RC70p, RC70VO, and their respective US-market variants, covering smooth-drum and padfoot configurations.
- Protects Hydraulic System Integrity: — Keeps hydraulic fluid temperatures within operating range, preventing viscosity breakdown, seal degradation, and premature pump and motor wear during sustained compaction work.
- Critical Cooling System Component: — A failed or degraded cooler can cause hydraulic overheating, triggering automatic shutdowns and accelerating wear across the drivetrain — replacing it promptly restores safe, continuous operation.
A water oil cooler is a combined heat exchanger that uses engine coolant flow to regulate the temperature of hydraulic fluid circulating through the machine. On a single-drum soil compactor like the RC50 and RC70 series, the hydraulic system powers the drum drive, the vibration circuit, and the steering, all of which generate significant heat during continuous operation. When the cooler fails or becomes restricted, hydraulic fluid temperatures climb rapidly, leading to fluid degradation, seal failure, and potential damage to pumps and motors throughout the system.
