Keep your Furuno radar system running smoothly with the essential Brush/Carbon F/D8G-516 DC24V replacement part. Designed specifically for the D8G-516 radar antenna gearbox motor, this carbon brush ensures reliable performance in demanding marine conditions. As a genuine Furuno component, it upholds the brand’s legacy of durability and precision engineering, trusted by professional mariners and recreational boaters alike.
Why Carbon Brushes Matter for Your Radar Motor
Carbon brushes are the unsung heroes of electric motors, maintaining electrical contact to power the rotor while handling high-speed rotation and friction. Over time, especially in harsh saltwater environments, they wear down, leading to reduced radar antenna rotation speed, erratic scanning, or complete motor failure. Replacing them proactively prevents costly downtime and keeps your navigation radar operating at peak efficiency.
This DC24V brush is precision-engineered to match the exact specifications of the D8G-516 gearbox motor, providing seamless compatibility and restoring full rotational power. Unlike generic alternatives, Furuno’s original brushes minimize sparking, reduce wear on the commutator, and extend the overall lifespan of your radar system.

Signs Your Radar Motor Brushes Need Replacement
Spotting wear early can save you from radar blackouts at sea. Watch for these common indicators:
Slower or inconsistent antenna rotation
Intermittent radar display or weak echoes
Unusual motor noise or sparking visible during operation
Reduced scanning range or sector blanks on the screen
Regular inspections during routine servicing—every 1,000 hours of operation or annually—help catch issues before they escalate. Pair this brush replacement with commutator cleaning for like-new performance.
Installation Tips for Optimal Results
Swapping out carbon brushes is a straightforward DIY task for those familiar with marine electronics:
Power down and disconnect the radar system.
Access the gearbox motor by removing the antenna cover (consult your Furuno manual for model-specific steps).
Gently remove worn brushes, noting their orientation.
Insert new brushes, ensuring springs are properly tensioned.
Reassemble, test rotation, and recalibrate if needed.
Always work in a dry environment and wear anti-static gloves to protect sensitive components. If you’re unsure, consult a certified marine technician to avoid voiding warranties.
Enhancing Your Furuno Radar’s Longevity
Furuno radars like those using the D8G-516 motor are built for the long haul, but proactive maintenance is key. Combine brush replacements with lubrication of bearings and alignment checks to maximize uptime. This not only improves safety through reliable target detection but also preserves resale value for your vessel.
