The Husqvarna 593491201 Gearbox is a genuine OEM component designed for the DuratiqT6, DuratiqT8, DuratiqX6, DuratiqX8, HTCT8, HTCX8, and HTCRX8 floor grinders. As a direct factory replacement, this gearbox delivers the exact mechanical specifications required to restore full drive function to your machine. DHS Equipment supplies this part to help keep your floor grinder performing at the level your work demands.
Key Features
- Genuine OEM Gear Tolerance — manufactured to Husqvarna's precise gear mesh and torque specifications, ensuring correct load transfer from the drive motor to the grinding heads without slip or backlash.
- Direct-Mount Replacement — engineered to bolt directly into the gearbox housing position on compatible machines, matching original mounting interfaces and output shaft dimensions.
- Broad Floor Grinder Compatibility — fits the DuratiqT6, DuratiqT8, DuratiqX6, DuratiqX8, HTCT8, HTCX8, and HTCRX8 floor grinder lines; cross-reference part number 593491201 against your parts diagram to confirm fitment for your specific unit.
- Restored Grinding Head Drive — a correctly functioning gearbox transmits power evenly to the planetary heads, maintaining consistent surface contact pressure and finish quality; a worn or failed unit causes uneven grinding, vibration, and loss of head rotation.
- Operational Safety Assurance — an OEM-spec gearbox maintains the designed torque limits and housing integrity, reducing the risk of unexpected mechanical failure during operation on active job floors.
The gearbox is the central power-transmission component in a floor grinder's drive system. It receives rotational input from the electric motor and converts it — at the correct speed and torque ratio — to drive the planetary grinding heads across the floor surface. When the gearbox wears or fails, the grinding heads lose consistent rotational force, resulting in poor surface finish, excessive vibration, and potential damage to surrounding drivetrain components. Replacing it with a genuine Husqvarna part restores the mechanical relationship between motor output and head speed that the machine was engineered to deliver.
