The Wacker Neuson 5100012729 is a genuine OEM Hollow Core Screw designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, and RD18-100C variants. As a direct OEM replacement sourced through the Wacker Neuson parts program, the 5100012729 matches the original component specification so it installs into the machine exactly as the factory-fitted part did. Fitment spans the full RD18 family — covering standard, SE, US, and.3-revision models — making this a versatile stocking part for operators and service shops running multiple RD18 configurations. Verify your machine number against the fitment list before ordering to confirm the correct application.
Key Features
- Genuine OEM Integrity — Manufactured to Wacker Neuson's original specification, ensuring the hollow-bore geometry and thread profile match what the machine was built with.
- Direct Drop-In Replacement — Threads and dimensions correspond to the original mounting point, so installation follows the same procedure as the factory part.
- Broad RD18 Family Coverage — Compatible across RD18-80, RD18-100, and RD18-100C models, including SE, US, and .3-revision configurations.
- Maintains Fluid or Pressure Routing Integrity — The hollow core design allows passage of fluid, lubricant, or pressure through the fastener; a worn or damaged screw can compromise that internal flow path and affect system performance.
- Revision-Specific Availability — Covers multiple build revisions of the RD18 platform, reducing the risk of ordering the wrong part across a mixed fleet.
A hollow core screw is a fastener with a precision-bored passage through its center, allowing fluid, grease, or hydraulic pressure to travel through the screw itself as part of the machine's internal circuit. In compaction equipment like the RD18 tandem roller, this type of screw is commonly used where a fluid or lubricant delivery point must coincide with a structural fastening location. If the screw becomes damaged, corroded, or blocked, the flow through that passage is interrupted — which can lead to inadequate lubrication, pressure loss, or component wear in the system it serves.
