This service kit features an aluminium bearing protection ring (BDU3xx) to safeguard the bearing L3 on the drive unit. It comes with 8 aluminium bearing rings and a 20g tube of grease, ensuring long - lasting performance and protection for your e - bike motor.

Using this service kit is easy. First, make sure your e - bike is turned off. Remove the old bearing protection ring from the drive unit. Clean the area around the bearing L3. Then, take one of the 8 aluminium bearing rings and carefully place it on the bearing. Apply a small amount of the 20g tube of grease to the ring for smooth operation. Make sure the ring is properly seated. When it comes to maintenance, check the bearing ring periodically for any signs of wear or damage. If you notice any issues, replace the ring with a new one from the kit. Keep the grease tube in a cool, dry place to maintain its quality. Also, avoid getting water or dirt on the bearing during the installation process.
