The Wacker Neuson Lockwasher is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this lockwasher is manufactured to the exact tolerances required for secure fastener retention in these tandem roller applications. It is a direct-fit replacement that installs exactly like the original, with no guesswork or modification needed. If you are servicing or rebuilding an RD27-series roller, confirming the correct part number before ordering ensures a proper match every time.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact material and hardness specifications, ensuring the lockwasher provides consistent clamping force without deforming under torque load.
- Direct-Fit Replacement — Designed to seat and function identically to the original, dropping into the same fastener stack without the need for adjustment or rework.
- Confirmed Fitment for RD27-Series Rollers — Verified compatible with the RD27-100 and RD27-120 hydrostatic vibratory rollers, so you can order with confidence for these machines.
- Fastener Integrity Under Vibration — In a vibratory roller environment, fasteners are exposed to continuous oscillation. A properly rated lockwasher prevents loosening and maintains joint clamping force through demanding compaction cycles.
- Correct Part, First Time — Using genuine OEM part number 5000162422 eliminates the risk of dimensional mismatches that can lead to fastener failure or unplanned service intervals.
A lockwasher is a hardened fastening component placed beneath a nut or bolt head to resist loosening caused by vibration, rotation, or thermal cycling. In a hydrostatic vibratory roller like the RD27-series, where the machine's compaction mechanism generates continuous vibration throughout the drivetrain and frame, maintaining proper fastener tension is critical to structural integrity and safe operation. When a lockwasher wears out, deforms, or is missing entirely, fasteners can back out gradually, leading to loose assemblies, accelerated wear on mating components, and potential mechanical failure in the field.
