To remove the bottom bracket bearings
The Cronus bottom bracket bearing system is designed to be a slip t. However, after the
rst installation some bearings might be tight. If the bearings do not easily come out by
hand, you may use the following method to remove them.
1. Slide the crank axle into the bearing so that the bearing is over the non-drive side of
the axle, about 1 inch (25 mm) from the non-drive end.
2. Gently rock the axle while you pull the axle out.
Inspecting the bottom bracket
Every 3 months check the bottom bracket adjustment.
To check the bottom bracket bearing adjustment
1. Lift the chain from the chainrings.
2. Rotate the crank so that one of the arms is parallel to the seat tube.
3. Put one hand on the crank arm and one hand on the seat tube, and attempt to move
the crank arm laterally toward and away from the seat tube.
4. Spin the cranks.
If the crank feels or sounds loose, or if the motion stops abruptly or you hear a
grinding noise coming from the bearings, readjust the bearings or take the bike to
your Gary Fisher dealer.
