The Wacker Neuson is a genuine OEM Lock Washer designed for a broad range of Wacker Neuson equipment, including the RT82-SC2, RT56-SC2, RTx-SC2, RTL82-SC3, RTLx-SC3, RTK82-SC3, and RTKx-SC3 remote-controlled vibratory trench rollers, PDT and PDI series diaphragm trash pumps, CRT series ride-on concrete trowels, and SP series vibratory truss screeds. As a direct OEM replacement sourced from Wacker Neuson, part number is manufactured to the exact material and dimensional specifications of the original hardware. This wide cross-machine fitment makes the Lock Washer a practical stocking item for fleet operators and service technicians running multiple Wacker Neuson product lines.
Key Features
- OEM-Spec Spring Tension: — Manufactured to the precise temper and tooth profile of the original, ensuring consistent locking force and resistance to vibration-induced loosening across all listed applications.
- Drop-In Hardware Replacement: — Matches the original bore diameter, outside diameter, and thickness so it seats correctly against the mating fastener and surface without rework or shimming.
- Broad Wacker Neuson Fitment: — Verified for RT/RTL/RTK vibratory trench roller families, PDT/PDI diaphragm trash pumps, CRT ride-on trowels, and SP vibratory truss screeds — one part number across multiple machine lines.
- Fastener Integrity Under High Vibration: — Compaction and pump equipment subjects every fastener to continuous cyclic loads; a correctly functioning lock washer prevents fastener back-out that can lead to component misalignment or structural looseness.
- Genuine Wacker Neuson OEM Part: — Supplied as an authorized OEM component, meaning the alloy grade and heat treatment match exactly what Wacker Neuson engineers specified for these assemblies.
A lock washer is a hardened spring or toothed ring placed beneath a bolt or nut to resist self-loosening caused by vibration, thermal cycling, or dynamic loads. When installed, the washer's teeth or spring action bite into both the fastener bearing surface and the mating component, creating mechanical resistance that keeps the fastener torque from backing off during operation. When a lock washer is worn flat, cracked, or missing entirely, fasteners can gradually loosen, leading to play in critical joints, accelerated wear on surrounding components, and — in severe cases — loss of structural integrity in the assembly it secures.
