Key Features
- Genuine OEM Spec Tolerance — Manufactured to Husqvarna's exact dimensional specifications, ensuring the correct interference fit between shaft and hub — critical for a small drive component where even minor dimensional variation causes slippage or wear.
- Drop-In Shaft Replacement — Matches the original keyway profile exactly, allowing direct installation into the shaft slot without machining or adjustment.
- Broad K-Series Compatibility — Fits a wide range of Husqvarna power cutters including the K2500, K3600, K650, K700, K650CutnBreak, 3122K, K1250, and K1260.
- Restored Torque Transmission — A worn or sheared Woodruff Key causes the blade hub to slip on the shaft, resulting in loss of cutting power and potential blade runout. Replacing this key restores positive torque transfer and consistent blade rotation.
- Safety-Critical Drive Component — Proper blade hub engagement is essential for safe power cutter operation. Using a correctly dimensioned OEM key prevents hub movement that could compromise blade control during cutting.
The Woodruff Key is a small, semicircular drive key that seats into a matching slot milled into the crankshaft or drive shaft, locking the blade hub or clutch drum in a fixed rotational position relative to the shaft. It transmits torque from the shaft to the hub and prevents the two components from rotating independently of one another. When this key shears or wears — typically the result of shock loading or an overdriven blade — the hub loses its drive engagement, cutting performance drops immediately, and continued operation risks blade instability.
