Key Features
- OEM-Matched Shaft Tolerancing — Manufactured to Husqvarna's exact dimensional specifications, ensuring the blade seats and runs concentric without vibration or runout issues common with imprecise replacements.
- Integrated Tachometer Drive (735117801) — Includes the tach interface component, so blade speed monitoring is restored alongside the mechanical shaft — no separate sourcing required.
- Direct Fit for Multiple Floor Saw Models — Engineered to install directly into the FS6600D, FS6600DJDT, FS6600DT, FS6800D, and FS8400D floor saws without alteration.
- Restored Cutting Accuracy — A worn or damaged bladeshaft causes blade wobble, uneven cuts, and accelerated blade wear; replacing it with this OEM unit restores cutting depth consistency and surface quality.
- Structural Integrity for Heavy-Duty Use — Built to withstand the continuous rotational loads and vibration demands of walk-behind flat sawing in concrete and asphalt applications.
The bladeshaft is the central rotating spindle that transfers power from the saw's drive system to the diamond blade, keeping the blade aligned and spinning at the correct speed under load. A properly functioning bladeshaft is critical to cut quality — any wear, bending, or damage to this component translates directly into blade wobble, off-spec cut width, and increased stress on bearings and drive components. The integrated tachometer coupling on this assembly also feeds blade RPM data to the machine's monitoring system, allowing operators to verify that the blade is running within its safe operating speed range during use.
