The Wacker Neuson 5000112015 is a genuine OEM Lock Nut designed for the RD12, RD12A, RD16, and RD11 series tandem rollers. As a direct factory replacement, this Lock Nut meets the original assembly specifications for these walk-behind and ride-on double-drum vibratory rollers. Fitment covers a wide range of configurations including solid ROPS, foldable ROPS, and hydrostatic variants across the RD series lineup. Ordering by part number 5000112015 ensures you receive the correct fastener for your specific machine configuration.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact thread form, hardness, and locking specification called out in the original Wacker Neuson assembly, ensuring the fastener holds torque correctly in a high-vibration roller environment.
- Drop-In Replacement — Matches the original thread pitch and profile for straightforward installation without rework or thread chasing.
- Broad RD Series Fitment — Compatible with RD11, RD11A, RD11V, RD12, RD12A, RD16-90, and RD16-100 tandem rollers across solid ROPS, foldable ROPS, and hydrostatic configurations.
- Vibration-Resistant Locking — The locking feature is critical on double-drum rollers where continuous compaction cycles generate sustained vibration that can back off standard fasteners over time.
- Verified Part Number — Part number 5000112015 is confirmed across multiple RD series machine numbers, so you can order with confidence that this is the correct component for your roller.
A lock nut is a fastener engineered to resist loosening under vibration and dynamic loads. Unlike a standard hex nut, it incorporates a locking mechanism — such as a nylon insert or a prevailing-torque thread form — that maintains clamping force even when the joint is subjected to repeated shock or oscillation. On a tandem roller like the RD series, where the drum vibration system runs continuously during compaction passes, maintaining correct fastener torque is essential to keeping critical assemblies secure. A loose or missing lock nut can allow components to shift, accelerate wear on adjacent parts, and ultimately lead to more significant mechanical failures.
