The Wacker Neuson is a genuine OEM Lock Washer 1/4 designed for the CRT46KHN, CRT46KHO, and CRT46ASO ride-on concrete trowels. Sourced directly from Wacker Neuson, this washer meets the exact material and dimensional standards specified for these machines. As a genuine OEM component, the installs as a direct, spec-matched replacement for the original hardware — no guesswork on sizing or grade. If you are servicing a CRT46-series ride-on trowel, this is the correct lock washer for the job.
Key Features
- Genuine OEM Hardness and Temper Rating — Manufactured to the exact material grade specified by Wacker Neuson, ensuring the washer delivers the correct clamping load and spring tension for 1/4-inch fastener applications.
- Direct Hardware Replacement — Matches the original 1/4-inch specification precisely, dropping into place on existing fasteners without resizing or shimming.
- CRT46-Series Fitment Confirmed — Compatible with CRT46KHN, CRT46KHO, and CRT46ASO ride-on concrete trowels, covering both kohler-engine and alternative-spec variants in the CRT46 family.
- Maintains Fastener Integrity Under Vibration — Lock washers resist fastener back-out caused by the continuous vibration generated during troweling operations; a worn or missing washer can allow bolted connections to loosen progressively during use.
- Critical Fastening Hardware — On rotating and structural connections in ride-on trowels, a failed or omitted lock washer can lead to fastener loosening at safety-critical points; using the correct OEM-spec washer keeps bolted assemblies secure through full operating cycles.
A lock washer is a hardened ring with a split or formed profile that bites into both the fastener face and the mating surface to resist rotational loosening. On ride-on concrete trowels like the CRT46 series, engines, gearboxes, and trowel arm assemblies generate sustained vibration that can gradually back out standard fasteners. By maintaining spring tension under the fastener head, the lock washer keeps bolted joints tight through repeated operating cycles. A worn, deformed, or missing lock washer allows fasteners to loosen over time, which can lead to misalignment, component damage, or unsafe operation.
