The Wacker Neuson 5100021564 Cap is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. Sourced directly from Wacker Neuson, this cap is manufactured to the exact standards of the original part it replaces, ensuring a correct, trouble-free installation every time. Fitment spans the full RD7 family, making this the right cap whether you're servicing an RD7 Tandem Roller, RD7He, RD7Ye, or any walk-behind roller variant in that lineup.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact material and dimensional tolerances, so the cap seals and seats the way the original was engineered to.
- Drop-In Replacement — Matches the original mounting interface on RD7 series rollers, with no trimming, shimming, or adapting required to install.
- Broad RD7 Series Coverage — Confirmed fitment across the RD7, RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, including both North American and standard configurations.
- Protects Critical Internal Components — A properly seated cap keeps contaminants out of the assembly it covers; a cracked or missing cap invites dirt, moisture, and debris that accelerate wear on components beneath it.
- Verified OEM Part Number — Order by part number 5100021564 with confidence — cross-referenced across the full RD7 family to confirm accuracy before purchase.
A cap serves as a protective closure for an opening in a housing, port, or shaft end on the machine. Its job is straightforward but essential: it keeps contaminants such as dust, water, and debris from entering the assembly underneath it while also retaining any fluid, grease, or pressure where required. When a cap is cracked, lost, or deteriorated, the exposed opening becomes a direct path for contamination that can damage bearings, seals, or other internal components. Replacing a worn or missing cap promptly is one of the simplest ways to preserve the service life of surrounding parts on the roller.
