Wacker Neuson 5000163963 Suction Reservoir to Pump Hose RD16

The Wacker Neuson is a genuine OEM Suction Reservoir to Pump Hose RD16 designed for RD16-90 and RD16-100 series tandem vibratory rollers. As a factory-sourced component, it is manufactured to the same material and dimensional standards as the original part, ensuring a correct installation into the hydraulic circuit of these machines. This hose is confirmed for use across multiple RD16-90 and RD16-100 configurations, including standard and hydrostatic drive variants. Replacing a worn or damaged hose with the genuine Wacker Neuson helps maintain proper hydraulic fluid flow and keeps your roller operating at full capacity.

Key Features

• Genuine OEM Hydraulic Hose Construction — Manufactured to OEM pressure ratings and internal diameter specs, ensuring correct flow characteristics between the suction reservoir and pump on RD16-series rollers.
• Direct-Connect Replacement — Engineered to match the original hose routing and end fittings, allowing straightforward swap-out without reworking hydraulic lines or adapting connections.
• Broad RD16 Series Fitment — Compatible with RD16-90 and RD16-100 tandem vibratory rollers, including standard vibratory and hydrostatic drive configurations.
• Protects Pump Priming and Hydraulic Integrity — A correctly functioning suction hose maintains uninterrupted fluid supply to the pump; a cracked or collapsed hose can cause cavitation, pump starvation, and loss of drive or compaction force.
• Fuel and Fluid Resistance — Built from hose materials suited to sustained hydraulic fluid exposure, resisting internal degradation and external wear common in roller applications.

The suction hose on an RD16 tandem roller carries hydraulic fluid from the reservoir to the hydraulic pump, forming the intake side of the machine's hydraulic circuit. Without a sound, properly seated hose in this position, the pump cannot draw sufficient fluid, which leads to cavitation, overheating, and eventual pump failure. A leaking or collapsed suction hose also introduces air into the system, causing erratic drive response and reduced compaction output — symptoms that can easily be mistaken for a pump or motor fault. Replacing this hose at the first sign of cracking, seeping, or softening is one of the most cost-effective ways to protect the hydraulic system on your RD16-series roller.
