The Husqvarna 504827007 Blade Shaft is a genuine OEM component designed for the FS8400D floor saw. Sourced directly from Husqvarna, this replacement delivers an exact dimensional match to the original, ensuring correct blade seating, alignment, and torque transfer right out of the box. DHS Equipment supplies this part to help keep your floor saw performing at full capacity on the job.
Key Features
- OEM-Matched Construction — Manufactured to Husqvarna's original material and dimensional specifications, so shaft diameter, thread pitch, and keyway geometry match the original exactly.
- Direct Drop-In Replacement — Engineered to mount in the same position as the factory shaft, using existing hardware and mounting points on the FS8400D.
- FS8400D Floor Saw Compatibility — Confirmed fitment for the FS8400D, a heavy-duty walk-behind flat saw used in slab cutting and road work applications.
- Restored Blade Drive Integrity — A correctly fitted blade shaft maintains true blade rotation, prevents lateral runout, and allows the saw to track cleanly through concrete and asphalt at rated depth.
The blade shaft is the central rotating component that connects the drive system to the cutting blade on a walk-behind floor saw. It transmits power from the engine or motor to spin the diamond blade at cutting speed while keeping it precisely centered and stable. A worn, bent, or damaged blade shaft causes blade wobble, uneven cuts, accelerated blade wear, and excessive vibration — all of which reduce cutting accuracy and put additional stress on surrounding drivetrain components. Replacing the shaft with a genuine OEM part restores the mechanical alignment the machine was built around.
