The Wacker Neuson Top Cover is a genuine OEM component designed for the RD and RC series tandem rollers, including the RD18, RD24, RD27, RD40, RD45, RC50, RC70, and RC110 model families. As a factory-original part, the is manufactured to the same specifications as the cover that shipped with your machine, ensuring a consistent, accurate replacement every time.

Key Features
- Factory-Original Construction — Genuine OEM part sourced directly through Wacker Neuson, manufactured to the same material and dimensional standards as the original top cover on your machine.
- Broad RC and RD Series Coverage — Fits RD18, RD24, RD27, RD40, and RD45 tandem rollers as well as RC50, RC70, and RC110 models, including CAB, ROPS, DPF, and open-rollbar variants.
- Drop-In Replacement — Designed to align with existing mounting points on the machine housing, so installation follows the same procedure as the original part without modification to surrounding components.
- Structural Protection for Internal Components — A properly fitted top cover shields internal machine components from debris, moisture, and jobsite contamination that can accelerate wear on sensitive parts beneath.
- Correct Part for Multiple Build Variants — One part number covers a wide range of serial-number-specific configurations, reducing the risk of ordering an incompatible cover for your specific machine build.
The top cover on a tandem roller serves as the primary protective enclosure over the machine's upper housing, shielding internal components — including engine ancillaries, hydraulic lines, and electrical systems — from dust, water, and physical impact during operation. When a top cover becomes cracked, warped, or damaged, it compromises that protection and can lead to accelerated wear or contamination of the components it covers. Replacing a damaged cover promptly with a correct-fit OEM part like the Wacker Neuson 5100066921 restores the machine's designed level of protection and keeps it operating as intended.
