Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact tolerances, this key delivers the precise engagement and retention characteristics required for dependable ignition or drive operation.

- Broad Equipment Compatibility — A verified fit for the CRT48 and CRT48PS power trowels, FS3500G and FS4600G floor saws, and the MS510 and MS510G tile and masonry saws.
- Restored Mechanical Engagement — A worn or missing key allows relative movement between shaft and hub, causing slippage or complete loss of drive; this replacement restores solid, locked engagement between components.
- Correct Part, Confirmed — Using the genuine Husqvarna part eliminates the risk of incorrect keyway clearance or premature failure that can result from improperly sized substitutes.
A key is a small but mechanically critical component seated in the keyway between a rotating shaft and a mating hub, pulley, or gear. Its role is to lock these two parts together so they rotate as one unit, transferring torque without slippage. When a key shears, deforms, or goes missing, the shaft spins independently of the driven component — causing loss of function and potential damage to the keyway itself. Replacing a damaged key promptly protects the surrounding hardware and restores full power transfer to the machine.
