The Wacker Neuson 5100012971 is a genuine OEM Locking Ring designed for the RD24, RD27, RD28, RD40, and RD45 series tandem rollers and the RC70 single-drum soil compactor. Sourced directly from Wacker Neuson, this part meets the same specifications as the original component installed at the factory. The 5100012971 covers an extensive range of configurations across the RD and RC families, including open-drum, combination, cab, DPF, and electric variants. If your tandem roller or soil compactor calls for a replacement Locking Ring, this is the correct OEM part to restore proper function.
Key Features
- Genuine OEM Retention Integrity — Manufactured to the exact dimensional tolerances required to maintain secure component engagement in Wacker Neuson roller and compactor driveline assemblies.
- Drop-In Replacement — Installs directly in place of the original Locking Ring with no rework to surrounding hardware or housings needed.
- Broad RD and RC Series Coverage — Fits RD24, RD27, RD28, RD40, and RD45 tandem rollers in open, combination, cab, DPF, and electric configurations, plus the RC70 single-drum soil compactor.
- Maintains Secure Component Retention — A correctly seated Locking Ring prevents axial movement and disengagement of rotating or retained components; a worn or missing ring can lead to accelerated bearing wear, vibration, and component damage.
- Verified OEM Part Number — Part number 5100012971 is the Wacker Neuson production part, ensuring you receive the correct ring for your specific machine configuration.
A locking ring is a precision retaining component used to secure rotating or sliding assemblies — such as bearings, shafts, or drum drive elements — in their correct axial position within the machine. It prevents unwanted movement that would otherwise cause misalignment, uneven wear, or mechanical failure of adjacent parts. When a locking ring becomes worn, cracked, or loses its retention force, the components it holds in place can shift under load, leading to vibration, noise, and potentially costly damage to the drum or drive assembly.
