The Wacker Neuson is a genuine OEM Oil Cooler Inlet Hose designed for the RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 series remote-controlled vibratory trench rollers. As a factory-sourced component, part is manufactured to the exact dimensions and material specifications required for a correct, leak-free installation in these machines. It covers an extensive range of RT-series configurations, including EU-spec variants and smooth-drum models, giving you confidence that this is the right part for your machine. When your existing hose shows signs of cracking, swelling, or seepage, replacing it promptly with the correct OEM hose protects the oil cooler circuit and keeps the hydraulic system running at the right temperature.
Key Features
- Genuine OEM Material Integrity — Hose compound and wall thickness match Wacker Neuson's original specification, ensuring pressure retention and resistance to hydraulic fluid degradation over time.
- Correct End Fittings and Routing — Molded to the original profile so it seats on the oil cooler inlet port without adaptation or rerouting of surrounding lines.
- Broad RT-Series Coverage — Fits RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 trench rollers across multiple serial-number ranges, including EU-spec and smooth-drum configurations.
- Protects Hydraulic Oil Temperature Control — A sound inlet hose maintains full flow to the oil cooler; a cracked or collapsed hose starves the cooler and can lead to overheating of the hydraulic system.
- Sourced Direct from Wacker Neuson — Supplied as a genuine OEM part under part number 5000165303, so you receive the same component installed at the factory.
The oil cooler inlet hose carries hydraulic fluid from the return circuit into the oil cooler, where heat picked up during operation is dissipated before the fluid recirculates through the system. On remote-controlled trench rollers like the RT56-SC and RT82-SC series, maintaining stable hydraulic oil temperature is critical — these machines rely on precise hydraulic control for drum vibration and directional drive, and elevated fluid temperatures degrade both performance and component life. When this hose cracks, collapses internally, or develops a leak, flow to the cooler is restricted or lost entirely, causing the hydraulic system to run hot and increasing wear on pumps, motors, and seals throughout the machine.
