The Wacker Neuson 5100012227 is a genuine OEM Hollow Core Screw designed for the RD-series walk-behind and ride-on articulated tandem rollers, covering the RD18, RD24, RD27, RD28, RD40, and RD45 model families. As a direct OEM part, the 5100012227 is manufactured to the exact specification required by Wacker Neuson for these machines, ensuring proper fit and function right out of the box. This screw is confirmed compatible across a wide range of RD-series configurations including standard, combination, and open-drum variants in both domestic and US-spec builds. Keeping the correct hardware in place is essential to maintaining the structural and hydraulic integrity of these high-cycle compaction machines.
Key Features
- Genuine OEM Specification: — Manufactured to Wacker Neuson's exact thread form, bore diameter, and material grade — critical for a hollow core screw where internal passage integrity directly affects fluid or fastener function.
- Drop-In Replacement: — Matches the original mounting interface on RD-series tandem rollers, allowing installation without modification to surrounding hardware or mating components.
- Broad RD-Series Coverage: — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families across standard, open-drum, combination, and SE configurations in both international and US-spec models.
- Maintains Clamping and Flow Path Integrity: — A hollow core screw serves a dual structural and passage role; using the correct OEM part prevents leaks, loss of clamping force, or restricted flow that can cause premature component wear.
- Direct OEM Source: — Supplied as a Wacker Neuson genuine part, backed by the manufacturer's parts program for fitment accuracy across all listed model numbers.
A hollow core screw is a fastener with a precisely machined internal bore that allows fluid, air, or a secondary line to pass through it while it simultaneously performs a clamping or retention function. On tandem rollers like the RD-series, these screws are commonly used in hydraulic or lubrication circuits where a threaded connection must also serve as a controlled passage point. If the screw becomes damaged, cross-threaded, or blocked, the result can be restricted flow, seal failure at the mating face, or loss of pressure in the circuit it serves — any of which can lead to erratic drum behavior or component damage during compaction operations. Replacing a worn or damaged hollow core screw with the correct OEM part restores the original bore geometry and sealing surface, keeping the circuit performing as engineered.
