The Wacker Neuson is a genuine OEM Upper Hose designed for the RD16-90, RD16-100, and CB14B series tandem vibratory rollers. As a direct factory replacement, this hose matches the original routing geometry and connection diameters to restore proper coolant flow through the engine. Wacker Neuson genuine OEM parts are produced to the same tolerances as the components installed at the factory, so you can be confident in the fit and integrity of this part. Confirm your machine model and serial number against the fitment list before ordering to ensure full compatibility.
Key Features
- Exact-Match Coolant Path: — Engineered to the original hose profile, ensuring correct routing between the engine and cooling system without rerouting or adapter fittings.
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and pressure specifications, maintaining the hose wall integrity demanded by the thermal cycles of a vibratory roller engine.
- Broad Tandem Roller Fitment: — Compatible with multiple RD16-90, RD16-100, and CB14B-900/1000 configurations, covering both standard and hydrostatic drivetrain variants.
- Sustains Engine Temperature Control: — A sound upper hose keeps coolant circulating at the correct pressure and volume; a cracked or collapsed hose leads to overheating and potential engine damage during compaction operations.
- Fuel System Safety Relevance: — Coolant leaks near hot engine surfaces create a fire hazard on operating equipment; replacing a degraded hose promptly keeps the cooling circuit sealed and the machine operating safely.
The upper hose is a critical link in the engine's cooling circuit, carrying heated coolant from the engine block to the radiator where heat is dissipated before the coolant returns. On vibratory tandem rollers like the RD16-90, RD16-100, and CB14B series, the engine works under sustained load and generates significant heat — making an intact, properly sealed upper hose essential to maintaining safe operating temperatures. When the hose cracks, collapses, or loses its seal at either end, coolant pressure drops and the engine overheats, which can result in costly damage to the cylinder head and related components.
