The Wacker Neuson 5100013380 is a genuine OEM Hollow Core Screw designed for the RD-series walk-behind and ride-on articulated tandem rollers. As a factory-sourced component, it is manufactured to the exact tolerances specified for these machines, ensuring correct installation and a secure, leak-free connection within the hydraulic or fluid-routing circuit it serves. This part covers an extensive range of RD-series configurations, including RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, open-drum, combination, DPF, and US-market variants. Keeping the correct hollow core screw in service is essential for maintaining fluid delivery integrity and overall drivetrain performance on your roller.
Key Features
- Genuine OEM Thread and Bore Specification — Manufactured to Wacker Neuson's exact thread pitch and internal bore dimensions, ensuring proper fluid flow rate and a leak-free seal at the connection point.
- Direct Drop-In Replacement — Engineered to install into the existing port without reworking fittings or adapters, maintaining the original fluid-circuit geometry of the RD-series roller.
- Broad RD-Series Coverage — A single part number covers RD18, RD24, RD27, RD28, RD40, and RD45 configurations, including open-drum, combination-drum, DPF-equipped, and US-market models.
- Fluid Circuit Integrity — A correctly seated hollow core screw maintains controlled, metered fluid passage through the assembly; a damaged or incorrect screw can cause uncontrolled flow, pressure loss, or external leakage that degrades compaction output.
- Corrosion-Resistant Construction — Built from materials suited to continuous exposure to hydraulic fluid or lubricant environments, supporting long service intervals on high-cycle compaction equipment.
A hollow core screw is a fastener with a precision-drilled internal passage that allows fluid — typically hydraulic oil or lubricant — to flow through it from one circuit point to another while also mechanically securing the connection. Unlike a standard bolt, the internal bore is calibrated to meter or route fluid at the correct rate, making its dimensional accuracy critical to system performance. When a hollow core screw becomes damaged, cross-threaded, or blocked, it can cause fluid starvation, pressure imbalances, or external leaks that directly affect the roller's vibratory system or hydraulic drive — symptoms that can be misdiagnosed as pump or valve failures until the screw itself is inspected.
