Wacker Neuson 5000163343 Suction Charge Pump Hose

The Wacker Neuson is a genuine OEM Suction Charge Pump Hose designed for the RD12A-90 tandem roller series. Sourced directly through Wacker Neuson's authorized parts program, this hose meets the original equipment specifications for the RD12A-90 platform, including the standard double-drum configuration, the base tandem roller build, and the foldable ROPS variant. Keeping the hydraulic charge circuit fully intact is critical on a tandem roller, and this OEM hose ensures the correct routing, connection sizing, and pressure rating are maintained exactly as designed.

Key Features

• OEM-Grade Hydraulic Integrity — Built to the original hose specification, including correct inner diameter and pressure rating for the charge pump circuit on the RD12A-90.
• Direct-Fit Replacement — Engineered to connect at the original mounting points without rerouting or adapting hydraulic fittings.
• RD12A-90 Series Coverage — Confirmed fitment across the double-drum, standard tandem roller, and foldable ROPS variants of the RD12A-90.
• Charge Circuit Protection — A healthy suction hose maintains consistent hydraulic fluid supply to the charge pump; a cracked or collapsing hose starves the circuit and can lead to pump cavitation and drivetrain damage.
• Hydraulic System Safety — A correctly seated charge pump hose prevents uncontrolled pressure loss in the drive circuit, helping the operator maintain predictable drum response on grade.

The suction charge pump hose carries hydraulic fluid from the tank or reservoir to the charge pump, which pressurizes the closed-loop hydrostatic drive circuit used to power the RD12A-90's drums. Without a steady, unrestricted supply of fluid on the suction side, the charge pump cannot maintain the minimum circuit pressure the hydrostatic transmission requires to function. A hose that has cracked, collapsed, or lost its seal will introduce air into the system, leading to cavitation, erratic drum behavior, and accelerated wear on the hydraulic pump and motor. Replacing a worn or damaged suction hose promptly is one of the most straightforward ways to protect the roller's drive system.
