The Wacker Neuson is a genuine OEM Radiator Bottom Hose designed for the RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, and RTx-SC2 series remote-controlled vibratory trench rollers. As a direct OEM replacement, this hose is produced to the exact dimensional and material specifications set by Wacker Neuson, ensuring a secure, leak-free connection between the radiator and the engine cooling circuit. It fits an extensive range of SC, SC2, and SC3 generation trench roller configurations, including standard, EU, and Compatec-equipped variants. Keep part number on hand to minimize cooling system downtime and get your trench roller back in the trench fast.
Key Features
- OEM-Matched Hose Material and Geometry — Manufactured to the exact inner diameter, wall thickness, and molded curvature specified by Wacker Neuson, ensuring a correct seal at both the radiator outlet and engine inlet connections.
- Drop-In Replacement for SC, SC2, and SC3 Generations — Fits the RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, and RTx-SC2 trench roller lines, including standard, EU-spec, and Compatec configurations, without modification.
- Broad Trench Roller Coverage — A single part number spans multiple machine generations and regional variants across the RT and RTL families, simplifying parts inventory for fleets running mixed trench roller lineups.
- Protects Engine from Thermal Failure — A cracked or collapsing bottom hose restricts coolant flow and can cause rapid engine overheating; replacing it at first sign of wear keeps operating temperatures stable during sustained compaction runs.
- Fuel and Coolant Resistant Compound — Built from hose material rated for the thermal cycling and chemical exposure inherent to diesel-powered equipment, resisting hardening, cracking, and interior degradation over time.
- Verified Wacker Neuson OEM Part — Sourced directly from Wacker Neuson's authorized parts supply chain under part number 5000155120, giving you confidence that the hose matches the original fitment exactly.
The radiator bottom hose carries coolant from the lower radiator tank back to the engine's water pump inlet, completing the closed-loop cooling circuit that keeps the diesel engine operating within its safe temperature range. On remote-controlled trench rollers like the RT and RTL series — which work in confined trench environments and run at sustained loads — maintaining consistent coolant flow is critical to protecting the engine from heat-related damage. When this hose softens, cracks, or collapses internally, coolant flow is restricted or lost entirely, leading to overheating, potential engine damage, and unplanned downtime on the jobsite.
