Key Features
- Exact OEM Dimensional Tolerancing — Manufactured to Husqvarna's precise width and depth specifications, ensuring the key seats fully in its keyway without play or slippage.
- Direct Drop-In Replacement — This key installs directly into the original keyway slot with no machining or modification to the mating shaft or hub.
- Broad Fitment Across Trowels and Floor Saws — Compatible with the CRT36, CRT48, and CRT48PS power trowels and the FS3500E floor saw, covering a wide range of Husqvarna Construction equipment.
- Positive Power Transfer — A correctly fitted key locks the rotating component firmly to the shaft, transmitting torque without slippage and maintaining consistent machine output.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna, this component meets the same material hardness and shear-strength standards as the part it replaces.
A key is a small precision component that fits into matching slots — called keyways — cut into both a shaft and a mating hub or gear, locking the two together so they rotate as one unit. Without a correctly sized key in place, the hub can spin freely on the shaft, resulting in complete loss of drive and potential damage to the keyway itself. When a key shears or wears, the driven component — whether a blade arbor, belt pulley, or gear — will no longer turn reliably, making prompt replacement essential to restoring normal machine operation.
