The Wacker Neuson 5100023650 Water Oil Cooler is a genuine OEM component designed for the RC50 and RC70 series single-drum soil compactors. This includes RC50, RC50P, RC70, RC70P, and RC70VO variants across both standard and US-spec configurations. As a direct OEM replacement, the 5100023650 is manufactured to the same specifications as the original unit, ensuring proper thermal regulation of hydraulic fluid throughout the compactor's operating cycle. Confirm your machine's model and serial number against the fitment list before ordering to ensure correct application.
Key Features
- Genuine OEM Thermal Specification: — Engineered to match the original heat-exchange capacity of the RC-series cooling circuit, maintaining correct hydraulic fluid operating temperatures under sustained compaction loads.
- Drop-In Replacement: — Matches the original mounting configuration, port sizing, and connection points for a straightforward swap without fabrication or adaptation.
- Broad RC-Series Fitment: — Compatible with RC50, RC50P, RC70, RC70P, and RC70VO models, covering both standard and US-spec machines across multiple serial number ranges.
- Protects Hydraulic System Integrity: — A functioning water oil cooler prevents hydraulic fluid from overheating, which can degrade seals, damage pumps, and lead to costly drivetrain failures during heavy compaction work.
- Verified OEM Part Number: — Sourced directly through Wacker Neuson's parts supply chain under part number 5100023650, eliminating guesswork on cross-reference compatibility.
The water oil cooler transfers heat from the machine's hydraulic oil into the engine coolant circuit, preventing hydraulic fluid temperatures from climbing into ranges that cause seal degradation, pump cavitation, and loss of compaction force. On single-drum soil compactors like the RC50 and RC70 series, the hydraulic system drives both propulsion and drum vibration simultaneously, placing sustained thermal demand on the cooling circuit throughout the workday. When the water oil cooler fails or becomes restricted, hydraulic performance drops noticeably — the machine may lose travel speed, vibration amplitude, or both — and unchecked overheating can cause cascading damage to downstream hydraulic components.
