Maintenance

To extend the service life of the CBD timing belt drive system, we recommend cleaning mud and dirt from the CBD on a regular basis. The gaps between the sprocket bars have been milled in such a way that particles of dirt are usually pushed out by the teeth moving over them. However, small rocks or twigs can become wedged in the system. Residues on the timing belt or sprockets may cause more wear and tear, as well as noise (e.g. squeaking or creaking).
 
  • Clear dirt from the belt’s teeth and the profiles of the teeth on both drive sprockets using a standard hand brush.
  • Carefully loosen trapped particles or firmly stuck rocks, for example by using a plastic wand. Never use a sharp-edged tool.
  • If the soiling is heavy, use a standard bicycle cleaner (biodegradable). The timing belt is resistant to soapsuds. To deal with these, spray the drive system with bicycle cleaner, let it work for a few minutes and then use a sponge to lather and clean.
  • An old toothbrush, for example, can be helpful for removing stubborn soiling in the gaps or in the profiles of the belt and sprockets.
  • Then rinse the drive system using plenty of water.
  • If you notice any unusual noises while operating the timing belt drive system, first check whether the noise is coming from soiling in the CBD and/or its individual components. Clean all the components.
  • If the noise persists even after thorough cleaning, a thin layer of dry silicone spray can be applied to the interior of the timing belt. This layer will prevent further debris getting trapped, improve the belt’s smoothness and reduce noise generation.
