The Wacker Neuson 5100011663 Cap is a genuine OEM component designed for the RD24, RD27, RD28, RD40, and RD45 series ride-on articulated tandem rollers. As a direct factory replacement, this cap is manufactured to the same specifications as the original part installed at the factory, ensuring a correct, trouble-free installation. Fitment spans an extensive range of RD-series configurations including standard, combination, offset drum, DPF-equipped, and electric-hybrid variants across multiple build revisions.
Key Features
- Genuine OEM Construction: — Produced to the exact material grade and dimensional tolerances of the original cap, ensuring proper sealing, retention, and fit within the assembly.
- Direct Drop-In Replacement: — Matches the original mounting interface on RD-series tandem rollers, so installation requires no rework or adaptation to the surrounding components.
- Broad RD-Series Compatibility: — Verified fitment across RD24, RD27, RD28, RD40, and RD45 model families, including DPF, offset, combination drum, and electric-hybrid configurations.
- Protects Critical Assembly Points: — A properly seated cap prevents contamination, moisture ingress, and debris from compromising the components it covers, preserving the integrity of the surrounding system.
- Backed by Wacker Neuson OEM Sourcing: — Sourced through the official Wacker Neuson parts network, giving you confidence in part number accuracy and product authenticity.
A cap serves as a protective closure for ports, openings, or fastener points within a machine assembly. On tandem rollers like the RD-series, caps prevent dirt, water, and debris from entering sensitive areas during operation in demanding compaction environments. When a cap is missing, cracked, or improperly seated, the exposed opening becomes a point of vulnerability — allowing contamination that can accelerate wear or lead to more significant component damage over time.
