The Wacker Neuson Lock Washer M10 is a genuine OEM fastening component designed for the CRT series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this lock washer maintains proper bolt tension and prevents fastener loosening under the continuous vibration and load cycles generated during concrete finishing operations. It fits an extensive range of CRT models spanning the CRT36, CRT48, and CRT60 series, including standard, high-speed, power-steer, dual-fuel, and electronic-steering variants.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to Wacker Neuson's specified material grade, ensuring the washer delivers consistent spring tension retention across M10 fastener applications on the trowel.
- Drop-In M10 Fitment — Sized to seat directly onto M10 hardware with no modification, maintaining correct clamp load on bolted joints throughout the machine.
- Broad CRT Series Coverage — Compatible with CRT36, CRT48, and CRT60 ride-on concrete trowels, including power-steer, dual-fuel, high-speed, and electronic-steering configurations.
- Vibration Resistance — Lock washers are critical in high-vibration environments; a worn or missing lock washer allows fasteners to back off, compromising structural integrity and trowel blade performance.
- Verified OEM Part — Part number 5000151475 is the factory-designated replacement, giving you confidence in specification accuracy before you order.
A lock washer is a hardened fastening component placed under a nut or bolt head to resist loosening caused by vibration, rotation, or dynamic load. On a ride-on concrete trowel like the CRT series, the machine generates sustained mechanical vibration throughout each finishing pass, which places constant stress on every bolted connection in the frame, drive system, and rotor assembly. When a lock washer wears flat, corrodes, or goes missing, the fastener it secures can back off gradually, leading to loose components, misalignment, and potential mechanical failure during operation. Replacing a worn lock washer promptly with the correct OEM part restores the clamping integrity of that joint and keeps the trowel performing as designed.
