The Husqvarna 531073811 Brush Rocker Complete is a genuine OEM component designed for the DM225D and DM225 concrete core drills. This assembly is sourced directly through Husqvarna's authorized parts network, ensuring an exact match to the original specification. The Brush Rocker Complete installs directly into the motor housing, restoring proper brush contact and motor function to your drill. DHS Equipment supplies this part to help keep your core drilling equipment operating at full capacity.
Key Features
- OEM Motor Brush Specification — supplied as a genuine Husqvarna part, this assembly matches the exact brush grade, rocker geometry, and spring tension of the original motor component, ensuring consistent current transfer.
- Complete Assembly Replacement — the Brush Rocker Complete includes all integrated components as a ready-to-install unit, eliminating the need to source individual sub-components separately.
- Confirmed Fitment for DM225D and DM225 — engineered specifically for these Husqvarna concrete core drill motors; cross-reference part number 531073811 against your parts diagram before ordering.
- Restored Motor Output — a worn or damaged brush rocker causes arcing, overheating, and loss of motor power; replacing this assembly brings drilling torque and speed back to operating specification.
- Electrical Safety Compliance — correct brush contact and rocker alignment prevent excessive sparking inside the motor housing, supporting safe and stable operation of the core drill.
The brush rocker assembly sits inside the electric motor of the core drill and holds the carbon brushes in firm, consistent contact with the motor's commutator. This contact is what allows electrical current to flow into the rotating armature, generating the torque that drives the drill. When the rocker becomes worn, cracked, or misaligned, brush contact deteriorates, leading to reduced motor power, erratic speed, excessive heat, and — if left unaddressed — permanent damage to the commutator itself. Replacing the Brush Rocker Complete at the first sign of motor performance loss is the most effective way to protect the broader motor assembly in your DM225D or DM225 core drill.
