GARY FISHER SERVICE INFORMATION

To install the non-drive side crankarm

1. Apply a light coat of grease to the inside of the other bearing seal.

2. With the grease side toward the bearing, slide the bearing seal onto the axle

(Figure 36).

3. Align the non-drive crank arm with the groove on the axle and slide the crank onto

the axle.

+

The non-drive crank arm should point 180 degrees opposite of the drive-side crank arm.

4. With the plastic installation tool, press the crank onto the axle (Figure 37) as far as it will go.

5. Release the installation tool and spin the cranks 10 to 20 revolutions.

6. Follow the Shimano instructions to complete the installation.

7. Follow the steps in “Inspecting the bottom bracket.”

To remove the bottom bracket bearings

The Cronus bottom bracket bearing system is designed to be a slip fit. However, after the
first 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.
