Wacker Neuson 5000112805 Lock Nut for RD Series Vibratory Rollers

The Wacker Neuson Lock Nut is a genuine OEM Lock Nut designed for the RD10, RD15, and RD25 Hydrostatic Double Drum Vibratory Rollers. Sourced directly from Wacker Neuson, this part meets the exact engineering tolerances specified for these machines. Cross-reference your model number against the confirmed fitment list below to ensure this is the correct replacement for your roller.

Key Features

• OEM-Grade Thread Integrity — Manufactured to Wacker Neuson's original torque and thread specification, so the Lock Nut seats and holds as intended without risk of backing out under vibration load.
• Direct Drop-In Replacement — Matches the original hardware profile exactly, allowing straightforward installation without reworking mounts or adjacent fasteners.
• Confirmed Fitment for RD Series Rollers — Verified for the RD10, RD15, and RD25 Hydrostatic Double Drum Vibratory Rollers across multiple serial number ranges.
• Vibration-Resistant Locking Action — A Lock Nut that loses its grip on a vibratory roller can allow critical assemblies to shift or separate during compaction passes; this genuine part restores the secure hold those assemblies depend on.
• Genuine Wacker Neuson Part — Supplied as an authentic OEM component, giving you confidence that part number 5000112805 is the correct specification for your machine — not a substituted equivalent.

A Lock Nut is a fastener engineered to resist loosening when subjected to continuous vibration, shock loads, or dynamic forces — exactly the conditions a double drum vibratory roller generates during compaction work. Unlike a standard nut, it incorporates a locking feature that maintains clamping force even as the machine cycles through repeated impact and movement. When a Lock Nut wears, strips, or backs off, the component it secures can shift out of alignment or come loose entirely, creating both a performance issue and a potential safety concern. Replacing a worn Lock Nut promptly keeps the surrounding assembly properly torqued and the machine operating as designed.
