The Husqvarna 504095401 Gear Box is a genuine OEM replacement built for the DM225 concrete core drill. Sourced directly from Husqvarna's construction equipment line, this component is manufactured to the same specifications as the original unit installed at the factory. DHS Equipment supplies this part to help keep your core drilling operations running at full capacity. Cross-reference part number 504095401 against your DM225 parts diagram to confirm fitment before ordering.
Key Features
- OEM-Matched Gear Tolerancing — manufactured to Husqvarna's exact gear mesh and torque specifications, ensuring the drive train operates within its intended power range on the DM225.
- Direct Assembly Fit — engineered as a drop-in replacement that aligns with the existing mounting points and shaft interfaces on the DM225 concrete core drill.
- DM225 Core Drill Compatibility — designed specifically for the DM225, so there is no guesswork when matching this gear box to your machine.
- Restored Drive Efficiency — a correctly functioning gear box transfers motor power to the drill bit smoothly and consistently; a worn or damaged unit causes loss of torque, erratic rotation, and potential core bit damage.
- Genuine Husqvarna Construction OEM Part — backed by Husqvarna's construction equipment parts program, this is not a generic substitute but the same component specified for the DM225 platform.
The gear box on a core drill motor is responsible for converting the motor's rotational output into the controlled, high-torque rotation needed to drive a diamond core bit through concrete, masonry, or other hard materials. It steps down speed while multiplying torque, allowing the drill to cut efficiently without stalling under load. When the gear box wears or fails, operators will notice reduced cutting power, unusual noise from the drive assembly, or complete loss of bit rotation — all of which halt production and risk damage to other drivetrain components.
