The Wacker Neuson is a genuine OEM Lower Radiator Hose designed for the RD27-100 and RD27-120 series tandem rollers. As a direct OEM replacement, this hose is manufactured to the exact dimensions and material specifications required for the cooling system on these hydrostatic vibratory rollers, including models RD27-100, RD27-120. Confirmed fitment covers both the RD27-100 and RD27-120 configurations across multiple machine builds, so you can order with confidence knowing this is the correct part for your roller. Sourcing a genuine Wacker Neuson ensures the integrity of your cooling circuit is maintained with a part that meets the same standards as the original.
Key Features
- OEM-Grade Hose Material — Manufactured to the same coolant-resistant compound and wall thickness as the original, maintaining pressure integrity throughout the cooling circuit.
- Exact-Fit Lower Hose Routing — Molded to match the factory bend profile and end dimensions, connecting directly to the radiator lower port and engine inlet without trimming or adapting.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 tandem rollers, including standard Hydrostatic Vibratory Roller builds and those equipped with Traction Control across multiple machine configurations.
- Cooling System Dependability — A properly functioning lower radiator hose maintains consistent coolant flow to the engine; a cracked or collapsed hose restricts flow and leads to overheating on the compaction site.
- Genuine Wacker Neuson OEM Part — Supplied directly through the authorized Wacker Neuson parts network, carrying part number 5000174276 for straightforward procurement and parts record accuracy.
The lower radiator hose carries coolant from the bottom of the radiator back to the engine's water pump, completing the cooling loop that keeps the engine operating within its safe temperature range. Unlike the upper hose, the lower hose is under suction from the water pump, which means it must maintain its shape under negative pressure — a hose that collapses internally will starve the engine of coolant even if it shows no visible exterior damage. On a tandem roller like the RD27 series, where the machine operates continuously under load in varying ambient conditions, a compromised lower radiator hose can escalate quickly from a slow coolant loss to full engine overheating.
