The grease areas should be about 1 inch (25 mm) wide. On the drive side, start at the bearing

seal. On the non-drive side, start at the splines and apply toward the drive side of the axle.

5. Insert the axle through the drive-side bearing in the bottom bracket (Figure 27).

To install the non-drive side crankarm

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

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

28).

3. Follow the TruVativ GXP installation instructions to complete to install the non-drive

crank arm.

5. 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.
