The Husqvarna 531073866 Gear Shifter is a genuine OEM replacement component designed for the DM225 and DM225D concrete core drills. As a factory-sourced part, it is manufactured to the same specifications as the original, ensuring correct engagement and smooth operation across gear ranges. DHS Equipment supplies this part to help keep your core drilling equipment running at full capability.
Key Features
- OEM-Matched Engagement Geometry — Manufactured to Husqvarna's original specifications, this gear shifter delivers the precise detent and lever travel needed for clean, positive gear changes on core drill motors.
- Drop-In Replacement — Engineered to match the original mounting points and interface of the DM225 and DM225D, this shifter installs using standard service procedures without adaptation.
- Compatible with DM225 and DM225D Core Drills — Confirmed fitment for both the DM225 and DM225D concrete core drill models, covering the most common variants in this drill motor family.
- Restores Full Speed-Range Control — A functioning gear shifter allows the operator to move between speed settings smoothly and accurately. A worn or damaged shifter can result in missed gear engagement, erratic speed selection, or an inability to change gears under load.
The gear shifter is a mechanical control component that enables the operator to select between the available speed ranges on the drill motor. By physically indexing the internal gear train into the correct position, it determines the rotational speed and torque output delivered to the core bit. When the shifter wears, breaks, or loses its detent, gear changes become unreliable — leading to loss of speed control and potential damage to the drivetrain. Replacing it with a genuine Husqvarna part restores accurate, confident speed selection and protects the integrity of the gearbox.
