The Husqvarna 544398901 Gear Wheel is a genuine OEM replacement designed for the DM330 concrete core drill. Sourced directly from Husqvarna, this gear wheel is manufactured to the exact tolerances required for proper meshing and power transfer within the drill motor's gear train. DHS Equipment supplies this part to help keep your core drilling equipment performing at full capacity.
Key Features
- OEM-Grade Tooth Geometry — Manufactured to Husqvarna's exact tooth profile and hardness specifications, ensuring smooth engagement and consistent torque transfer through the gear train.
- Direct Drop-In Replacement — Engineered to match the original mounting interface and gear pitch of the DM330, allowing straightforward installation without machining or modification.
- Confirmed DM330 Fitment — Verified for the DM330 concrete core drill; cross-reference 544398901 against your parts diagram before ordering to confirm correct application.
- Restored Drilling Power — A correctly functioning gear wheel maintains full rotational speed and torque delivery to the core bit, keeping cut rates consistent through reinforced concrete and masonry.
- Genuine Husqvarna Part — Backed by Husqvarna's OEM quality assurance, this component meets the same standards as the part originally installed on your drill at the factory.
The gear wheel is a core mechanical component within the DM330 drill motor's transmission, responsible for transferring rotational force from the motor to the drill spindle. It works in mesh with adjoining gears to step down speed and multiply torque, giving the drill the power needed to drive large-diameter core bits through hard materials. When a gear wheel wears or develops damaged teeth, the result is slippage, vibration, audible grinding, or a complete loss of drive — all of which halt productive drilling and place additional stress on surrounding drivetrain components. Replacing the gear wheel with a genuine OEM part restores the correct gear mesh and ensures the full torque load is transmitted efficiently and without mechanical play.
