If you are into DIY and want to extend the life of your ceramic bearings, then we are probably in the same camp. ;D
Bottom bracket like any other bearings in our bicycle requires some maintenance after several hundred hours of use. That is if you want them to continue working smoothly and quietly. Servicing your bottom bracket is a simple process that can be easy and rewarding with the correct tools. It requires removal of outboard bearing cups and extraction of bearing from the cups. That is all there is to it.
Tools and supplies that I used for this simple project:
Park Tool BBT9 - Bottom Bracket and Crank Arm Tool
Degreaser
Rags
Enduro Bottom Bracket Tool
Torque wrench(s)
Jewelry cleaner
small pick (to remove bearing seals)
Lightweight bearing grease
Here is also an excellent link from Park Tool on servicing external bottom brackets
Once the outboard bearing were removed from the bike, the Enduro bearing puller can be used to extract the bearing from the cups
Bottom bracket inside the tool
Bearing extracted
Remove bearing seals and put them in the jewelry cleaner for thorough cleaning
Bearing cleaned and ready for re-assembly
Re assembly of bearing
Installation is the reverse of removal.
Once you have completed servicing the bottom bracket bearings, rest assured that you will have many more hours from your bearings. By using the correct tools, servicing your bearings can be fun and rewarding.
