Note: Always inspect clutch bearings for damage after a crash. Bearings should always engage without backlash. To replace bearing you will need to use a 3mm SHCS to offset inside the coupler(there is a gap between the bearing and the bottom of the bearing bore). You can then use a spare shaft to press out the bearing. Note the bearing orientation when pressing it back in. If you do not have access to an arbor press, we recommend just purchasing a replacement coupler with bearing.
