Wacker Neuson 5000163965 Hose RD16 Suction to Charge Pump

The Wacker Neuson is a genuine OEM Hose RD16 Suction to Charge Pump designed for the RD16-90 and RD16-100 series tandem vibratory rollers. Sourced directly from Wacker Neuson, this hose meets the exact dimensional and pressure specifications of the original component. It is confirmed compatible across multiple RD16-90 and RD16-100 configurations, including standard hydrostatic and IRH variants. Installing the correct OEM part ensures a leak-free connection between the hydraulic suction circuit and the charge pump, keeping the drivetrain operating as engineered.

Key Features

• OEM-Grade Hose Construction — Manufactured to the original pressure rating and inner diameter spec, ensuring full hydraulic flow from the suction circuit to the charge pump without restriction or weeping.
• Direct-Fit Replacement — Engineered to match the original routing, end fittings, and hose length of the factory-installed part, so installation follows the standard service procedure without rerouting or adapting lines.
• Broad RD16 Series Coverage — Fits RD16-90 Tandem Roller, RD16-90 Hydrostatic Vibratory Roller (IRH), RD16-100, and RD16-100 Hydrostatic Vibratory Roller variants.
• Protects Charge Pump Integrity — A compromised suction hose starves the charge pump of hydraulic fluid, leading to cavitation, overheating, and accelerated pump wear. Replacing a cracked or collapsed hose at the first sign of degradation prevents costly drivetrain damage.
• Genuine Wacker Neuson Part — Part number 5000163965 is a factory-authorized component, ensuring the material grade and fitting spec match what left the production line.

The suction to charge pump hose carries hydraulic fluid from the reservoir or suction circuit into the hydrostatic charge pump, which maintains the minimum system pressure needed to keep the closed-loop drive circuit primed and responsive. Without adequate charge pressure, the roller's hydrostatic transmission loses its ability to deliver smooth, controlled propulsion and drum drive. A hose that has cracked, hardened, or collapsed internally will cause low charge pressure faults, erratic forward and reverse response, or full drive loss — making timely replacement critical to keeping the machine in productive service.
