The Husqvarna 541400448 Key is a genuine OEM component designed for the CRT36, CRT48, CT36, CT48, and CRT48PS power trowels. As a direct Husqvarna OEM part, it is manufactured to the exact specifications required for proper shaft and drive engagement on these machines. This Key fits CRT36, CRT48, CT36, CT48, and CRT48PS power trowels, making it the correct choice when restoring factory-spec operation. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Specification — Manufactured by Husqvarna to the exact dimensional tolerances required for positive drive engagement, ensuring the component seats and locks correctly without play or slippage.
- Drop-In Replacement Fit — Engineered to align directly with the original keyway geometry on compatible shafts, allowing straightforward installation without additional machining or fitting.
- Broad Power Trowel Compatibility — Confirmed fitment across the CRT36, CRT48, CT36, CT48, and CRT48PS ride-on power trowel models, covering both standard and pro-spec variants in the CT series.
- Restored Drive Integrity — A correctly fitted key maintains the fixed rotational relationship between mating components; a worn or sheared key causes slippage, vibration, and loss of trowel drive — replacing it promptly restores full machine function.
- Verified Part Number Cross-Reference — Cross-reference part number 541400448 against your machine's parts diagram to confirm correct application before installation.
A key is a small precision component that locks a rotating shaft to a mating hub, gear, or pulley, preventing relative rotation between the two parts. It transmits torque through the drivetrain and holds critical drive components in their correct angular position. When a key shears or wears, drive slippage occurs — the shaft spins independently of the component it should be driving — resulting in loss of trowel function and potential secondary damage to surrounding components. Replacing this part with the correct OEM piece restores the mechanical connection and full drivetrain performance.
