The Husqvarna 544128301 Gear Wheel Shaft is a genuine OEM component designed for the DM225 concrete core drill. Sourced directly from Husqvarna, this shaft meets the exact dimensional and material specifications of the original part, ensuring correct engagement with the drill motor's gear train. DHS Equipment supplies this part to help keep your core drilling equipment running at full capability. Cross-reference part number 544128301 against your DM225 parts diagram to confirm fitment before ordering.
Key Features
- OEM-Grade Material and Tolerancing — Manufactured to Husqvarna's original hardness and dimensional specifications, so the gear teeth mesh correctly under the torque loads typical of core drilling operations.
- Direct Drop-In Replacement — Engineered to the same shaft geometry and spline profile as the original, fitting into the DM225 gear housing without modification.
- Confirmed DM225 Fitment — Specifically validated for the DM225 concrete core drill motor, eliminating guesswork during repairs.
- Restored Power Transmission — A worn or damaged shaft compromises torque transfer from the motor to the drill bit, causing slippage and inefficient coring. Replacing it with this OEM shaft restores full, consistent power delivery.
- Structural Integrity Under Load — Built to withstand the continuous rotational stress of diamond core drilling through reinforced concrete, where shaft flex or wear accelerates gear damage throughout the drivetrain.
The Gear Wheel Shaft is a core drivetrain component inside the DM225 drill motor, transmitting rotational power from the motor's internal gear set to drive the spindle and, ultimately, the core bit. It works in constant mesh with mating gears, so precise geometry and surface hardness are critical — even minor wear or scoring on the shaft disrupts gear alignment and causes noise, vibration, and lost torque. When this shaft fails, the drill loses the ability to deliver consistent rotational force, making clean, accurate core holes impossible and risking further damage to surrounding gear components.
