The Husqvarna 542167485 Lock Nut is a genuine OEM replacement designed for CT36, CT48, CRT36, CRT48, and CRT48PS ride-on power trowels. Sourced directly from Husqvarna, this Lock Nut meets the exact specifications of the original hardware installed at the factory. It fits all five listed trowel models, making it the correct choice whether you are servicing a standard CT-series or a counter-rotating CRT-series machine. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Husqvarna's thread-form and torque-retention specifications, ensuring the nut holds secure under the vibration loads generated by ride-on power trowel operation.
- Direct-Thread Replacement — Matches the original fastener profile exactly, so it seats and torques to spec without rework or thread chasing on the mating component.
- Broad Trowel Fitment — Compatible with CT36, CT48, CRT36, CRT48, and CRT48PS power trowels, covering both standard and counter-rotating models in the Husqvarna ride-on trowel lineup.
- Secure Locking Retention — The locking feature resists loosening from continuous machine vibration, maintaining correct clamping force across blade arm assemblies and drive components.
- Verified Part Number — Cross-reference 542167485 against your machine's parts diagram to confirm the correct position and application before installation.
A lock nut is a fastener engineered to resist self-loosening under sustained vibration and dynamic loading — conditions that are constant on a ride-on power trowel working concrete. Unlike a standard nut, its locking mechanism maintains clamping force even as the machine cycles through varying speeds and blade pitch adjustments. When a lock nut loosens or fails, connected components can shift out of alignment, creating wear on adjacent parts and potential loss of control over blade geometry. Replacing a worn or damaged lock nut with the correct OEM part restores the mechanical integrity of the fastened joint and keeps the trowel operating as intended.
