DeWalt N558583 Carbon Brush – Genuine OEM Replacement Motor Carbon Brush

Part Number: N558583
Category: Power Tool Parts & Accessories → Motor Components → Carbon Brushes
Type: DeWalt N558583 Carbon Brush – Genuine OEM Replacement Motor Carbon Brush

The DeWalt N558583 Carbon Brush is a genuine OEM replacement motor brush designed for compatible DeWalt chop saws and jobsite table saws. Carbon brushes transfer electrical current from the stationary brush holders to the rotating armature, allowing the motor to operate efficiently while maintaining consistent power and electric braking performance. As normal wear items, carbon brushes gradually wear down with use and should be replaced periodically to restore optimal motor performance. Manufactured to original equipment specifications, the N558583 provides a direct-fit replacement for worn, cracked, or damaged brushes. It also replaces the earlier part number N039389.

Function of the Carbon Brush

The N558583 Carbon Brush is designed to:

• Conduct electrical current from the brush holder to the armature
• Maintain consistent motor power output
• Support proper electric braking performance
• Compensate for normal brush wear during operation
• Help ensure reliable motor startup
• Restore the original electrical performance of the tool

Using genuine OEM carbon brushes helps maintain efficient motor operation and reduce unnecessary wear on the armature.

Common Signs Replacement Is Needed

Replace the carbon brush if you notice:

• Reduced motor power
• Intermittent operation
• Difficulty starting the tool
• Excessive sparking at the motor
• Electric brake no longer functioning properly
• Brushes worn near the lead wire, cracked, chipped, or burned

Because carbon brushes are normal wear components, replacing them at the appropriate interval helps prevent unnecessary damage to the armature and other motor components.

Installation & Service Notes

Disconnect the tool from the power source before servicing.

Access the brush holders according to your tool's service manual and remove the worn N558583 Carbon Brush. Inspect the brush holder and commutator (armature) for excessive carbon buildup, scoring, discoloration, or other signs of damage before installing the new brush. Insert the replacement brush so it moves freely within the holder, reconnect the lead if applicable, and reinstall the brush cap. If both brushes show wear, replace them as a matched set to promote even motor performance. After installation, operate the tool without a load for several minutes to help the new brushes properly seat against the commutator.

Important: Always verify your tool model and original part number before ordering. If excessive sparking or poor motor performance continues after brush replacement, inspect the armature and brush holders for additional wear or damage.

Maintenance Recommendations

• Inspect carbon brushes periodically as part of routine tool maintenance.
• Replace both brushes together whenever possible.
• Keep motor ventilation openings clean to reduce heat buildup.
• Inspect the commutator whenever replacing brushes.
• Avoid operating the tool with severely worn brushes, as this can damage the armature.
• Use genuine OEM replacement parts to maintain factory fit, reliable motor performance, and long-term tool durability.
