The Wacker Neuson is a genuine OEM Lock Nut 3/4-10NC Thin designed for CRT36 and CRT46 series ride-on concrete power trowels. As a direct OEM replacement, part is produced to the same specifications as the original hardware, ensuring a correct thread engagement and proper clamping force on first installation. Verified fitment covers the CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO models. When hardware integrity matters on a high-cycle concrete finishing machine, sourcing the correct OEM part keeps every fastened joint performing as designed.
Key Features
- Correct 3/4-10NC Thread Form — Machined to the Unified National Coarse thread standard, this thin lock nut engages mating fasteners cleanly without cross-threading or binding.
- Thin-Profile Lock Design — The reduced-height profile allows installation in tight fastener stacks where a standard-height nut would not clear surrounding components on the trowel assembly.
- Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000088028 meets the original hardware specification for torque retention and material grade.
- Broad CRT Series Fitment — Confirmed for the CRT36ASO, CRT36ASN, CRT46ASO, CRT46KHN, and CRT46KHO ride-on concrete trowels — covering both 36-inch and 46-inch overlapping and non-overlapping configurations.
- Fastener Integrity Under Vibration — A worn or missing lock nut on a ride-on trowel allows critical joints to loosen under continuous operational vibration, leading to component misalignment or mechanical failure mid-pour.
A lock nut is a fastener designed to resist loosening caused by vibration and dynamic loading. The thin profile variant is used where axial space is limited, allowing it to function as a jam nut or secondary locking element alongside a primary fastener. On ride-on concrete trowels like the CRT36 and CRT46, rotating assemblies and engine-driven components generate sustained vibration throughout operation — conditions that will gradually back out standard fasteners. A correctly torqued lock nut maintains joint clamping force across the machine's full duty cycle, and a loose or absent one can allow parts to shift, accelerating wear on surrounding components and creating unsafe operating conditions.
