Husqvarna Construction Genuine OEM Spare Part

The Husqvarna Carbon Brush Set for DM 400, DM 430 Drill 598736402 is a genuine OEM spare part set designed to keep your Husqvarna DM 400 and DM 430 core drill motors running at full power and within factory specifications on 120V systems. This carbon brush kit includes the correctly sized, pre‑matched brushes for the motor, ensuring reliable electrical contact, smooth operation, and extended tool life for professional concrete drilling.

What is Husqvarna Carbon Brush Set 598736402?

The Husqvarna 598736402 Carbon Brush Set is a factory replacement carbon brush set specifically listed for the DM 400 and DM 430 concrete core drill motors.

Key identification details:

• OEM designation: “CARBON BRUSH SET 120V”.

• Husqvarna part number: 598736402.

• Intended models: Husqvarna DM 400 and DM 430 core drill motors (120V versions).

In DM 400 parts diagrams, this part appears in the electric/motor section as “carbon brush set 120V, ref. 13, art. 598736402,” with quantity required listed as one set per machine. For DM 430 diagrams, it’s similarly listed in the motor assembly as “carbon brush set 230V, 598736402” for that voltage variant, indicating it is also used as the brush set on 230V DM 430 configurations.

Compatible Models and Voltage Versions

The 598736402 carbon brush set is engineered for the Husqvarna DM 400 and DM 430 models, which are heavy‑duty electric core drill motors used for concrete and masonry drilling.

Compatibility highlights:

• Listed specifically as “Carbon Brush Set Spare Part 120V DM 400, DM 430” by core drill parts suppliers.

• Parts drawings from Husqvarna and European distributors show ref. 13 – 598736402 – Carbon brush set 120V (or 230V) in the DM 400 / DM 430 motor parts lists.

• A related part, 598736401, is also sold as a carbon brush set for DM 400 and DM 430, typically associated with 230V configurations; 598736402 is the labeled 120V set but is referenced as a carbon brush set for both drills in several catalogs.

If your DM 400 or DM 430 is a 120V/1‑phase machine, 598736402 is the correct OEM brush kit in most North American listings. For 230V units, many European diagrams still show 598736402 as “carbon brush set 230V,” so checking your voltage and parts list is important.

What Do Carbon Brushes Do in DM 400 / DM 430?

The DM 400 and DM 430 are powerful electric drill motors that use carbon brushes to transfer electrical current from the stationary power supply to the spinning armature inside the motor.

In these drills:

• The carbon brush set sits inside carbon brush holders (part 598736201), one on each side of the motor.

• As the motor runs, brushes wear down gradually from friction against the commutator.

• When brushes become too short or uneven, they can cause arcing, power loss, overheating, or motor failure.

The 598736402 set restores the brushes to factory length and material, ensuring correct electrical contact and safe operation of the DM 400 / DM 430 motor.

OEM Specifications and Quality

While Husqvarna does not publish the exact dimensions and hardness in retail listings, 598736402 is an original Husqvarna Construction OEM part, built for the specific current, voltage, and duty cycle of DM‑series core drills.

Key OEM advantages:

• Correct size and shape for the DM 400/DM 430 brush holders (598736201).

• Proper carbon grade and spring tension designed to balance long life with stable contact and minimal arcing under heavy drilling loads.

• Fully compatible with the motor housing and commutator design used in DM 400 and DM 430 production models.

This is different from generic “carbon brush” replacements, which may not match Husqvarna’s specification and can lead to increased wear or damage inside the drill motor.

Signs Your DM 400 / DM 430 Needs New Brushes

Carbon brushes are a consumable service item. Over time, they wear down and need replacement to avoid motor damage.

Typical signs that you should install a new Husqvarna Carbon Brush Set 598736402 include:

• Decreased power or intermittent operation when drilling.

• Visible sparking or arcing at the motor vents.

• Burning smell or excessive heat around the motor housing.

• Motor cutting out under load, especially on tough concrete cores.

• Visual inspection shows very short brushes or uneven wear.

Service diagrams and parts manuals for DM 400 / DM 430 highlight the carbon brush set as a standard maintenance component; many professional shops replace brushes proactively after a given number of hours or when symptoms appear.

Relationship to Other Electrical Spare Parts

When replacing the 598736402 carbon brush set, it is good practice to inspect related parts in the DM 400 / DM 430 electrical system.

Associated components include:

• 598736201 – Holder carbon brush: the plastic/metal holders that the brushes sit in.

• Motor housing (e.g., 598735701): protects the brush area and motor internals.

• Rings, washers, and screws (e.g., 598761901 ring, 598760901 screw) that secure the brush holders within the motor.

If a brush has worn unevenly or overheated, technicians often check the holders and commutator condition and may replace damaged holders at the same time as the brush set.

Where 598736402 Appears in Parts Diagrams

Official DM 400 / DM 430 parts diagrams show exactly where 598736402 fits.

Examples:

• One DM 400 drawing lists “Ref. 13 – 598736402 – Carbon brush set 120V – quantity required: 1.”

• A DM 430 motor partlist shows ref. 13 – 598736402 – Carbon brush set 230V, followed by rings and screws in the same sub‑assembly.
