Key Features
- Factory-Original OEM Construction — Manufactured to Husqvarna's exact engineering specifications, this tube assembly maintains the dimensional accuracy and material grade required for consistent blade shaft operation in demanding concrete cutting applications.
- Integrated Tachometer Pickup — The built-in tach feature allows the machine's RPM monitoring system to accurately read blade shaft speed, supporting proper engine management and operator awareness during cutting.
- Direct-Fit Replacement — Engineered to install directly into the blade shaft housing of compatible floor saws, this component connects to existing mounting points without modification to the surrounding assembly.
- Broad Floor Saw Compatibility — Confirmed fitment across the FS6600D, FS6600DT, FS6600DJDT, FS6800D, FS8400D, and RS8500D floor saws, covering multiple configurations within Husqvarna's heavy-duty walk-behind slab saw lineup.
- Restored Blade Drive Integrity — A worn or damaged blade shaft tube can introduce play into the cutting head, leading to blade wobble, inaccurate cuts, and accelerated wear on adjacent components. This replacement restores the rigid, precise alignment the assembly requires.
The blade shaft tube serves as the structural housing that supports and guides the blade shaft through the saw's drive assembly, keeping the cutting blade centered and stable under load. The integrated tachometer pickup works alongside the machine's instrumentation to monitor shaft rotation speed in real time, giving operators accurate RPM data essential for safe and efficient concrete cutting. When this tube is cracked, worn, or damaged, blade alignment suffers and the tach signal can become unreliable — both of which compromise cut quality and safe machine operation.
