The Husqvarna 531112019 Gear Wheel is a genuine OEM component designed for the DM406 concrete core drill. Sourced directly from Husqvarna, this part meets the exact engineering tolerances specified for the DM406 drive train, ensuring correct mesh, load transfer, and torque delivery. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- Genuine OEM Gear Tolerancing — Manufactured to Husqvarna's exact tooth profile and material spec, ensuring correct gear mesh and smooth power transfer under the high-torque demands of core drilling.
- Drop-In Drive Train Replacement — Engineered to the original mounting dimensions and gear geometry of the DM406, allowing direct installation without modification to surrounding drive components.
- DM406 Core Drill Fitment — Confirmed fit for the DM406 concrete core drill, so you can cross-reference part number 531112019 against your parts diagram with confidence.
- Restored Torque Transmission — A worn or damaged gear wheel causes slippage, uneven drilling speed, and accelerated wear on mating components; this replacement restores clean, consistent power delivery to the drill head.
- Protects Surrounding Drive Components — A correctly fitted gear wheel distributes load evenly across the drive train, reducing stress on adjacent gears and bearings and extending overall drivetrain service life.
The gear wheel is a core element of the drill motor's internal drive train, transmitting rotational force from the motor to the drilling spindle. It works in mesh with adjacent gears to step torque up or down to the speed and power level required for diamond core drilling through concrete and masonry. When a gear wheel wears, chips, or develops play, the result is lost drilling efficiency, increased vibration, and the risk of cascading damage to other drive components — making timely replacement critical to keeping the DM406 operating correctly.
