Ram® Carbon Brushes

Ram® Carbon Brushes are essential replacement parts for TECH 2000, 45000, OPTIMUS 35, OPTIMUS 45, and Primus handpieces. These high-quality, durable carbon brushes are rated for approximately 1,000 hours of operation and ensure optimal motor performance and longevity. Two versions are available based on your handpiece serial number. Item #8508 is for handpieces sold before 2016 with mixed alphanumeric serial numbers. Item #9605 is for handpieces sold from 2016 onward with 8-digit numeric serial numbers (16...., 17...., 18...., etc.). Installation is straightforward: unscrew the plastic cover, remove the two tiny screws on the metal brush plates, and pop out the brushes using the metal tabs or a small flat screwdriver. Brushes should wear evenly and gradually become concave. Periodically inspect for even wear and verify the spring tension remains intact. Clean the motor commutator with ultra-fine sandpaper if needed, and remove any dust or debris during maintenance. Abnormal wear patterns can damage the motor, so regular monitoring is essential for peak performance.
