The Husqvarna 581086803 2 Brushes With Popout Springs 230V is a genuine OEM replacement designed for the DM280 and DM340 concrete core drills. This component delivers an exact fit to the motor's brush holder assembly, ensuring the electrical contact geometry and spring tension match Husqvarna's original design specification for 230V operation. Cross-reference part number 581086803 against your parts diagram to confirm fitment before ordering. DHS Equipment supplies this part to help keep your core drill running at full capacity.
Key Features
- Correct Carbon Grade and Spring Tension — genuine OEM carbon brushes are produced to the exact conductivity rating and popout spring force specified for the DM280 and DM340 230V motor, preserving proper current transfer across the commutator.
- Matched 230V Motor Specification — rated and dimensioned specifically for 230V operation, so electrical load and brush wear characteristics align with the motor's designed duty cycle.
- Direct Drop-In Replacement — the brush and integrated popout spring assembly seats into the existing brush holders without modification, restoring the original contact angle and pressure immediately upon installation.
- Fits DM280 and DM340 Concrete Core Drills — confirmed OEM fitment for both DM280 and DM340 drill motors, covering a widely used range of Husqvarna professional core drilling equipment.
- Restored Motor Efficiency — worn brushes cause arcing, power loss, and accelerated commutator damage; replacing them with this genuine set restores clean electrical contact and full motor output.
- Electrical Safety Compliance — using correctly rated OEM brushes is critical in a 230V motor application; undersized or incorrect-grade brushes can cause overheating, excessive sparking, or premature motor failure.
Carbon motor brushes are the sliding electrical contacts that transfer current from the stationary power supply to the rotating commutator inside the drill motor. Over time, these brushes wear down through normal friction, and once they reach their minimum length the motor loses power, runs intermittently, or stops entirely. The popout spring serves a dual purpose: it maintains consistent contact pressure against the commutator during operation and automatically ejects the brush clear of the commutator when the brush is fully worn, protecting the commutator surface from damage. Replacing both brushes as a matched pair at the same service interval ensures even wear and maintains balanced motor performance in the DM280 and DM340.
