How to Use The Tool
Before using the tool, you must make sure the fork steerer tube has been cut to the
correct length for the headset assembly being used. And, you must find out the cor-
rect star nut to use for the fork and the correct depth it must be driven.
1. Start by placing the fork into a fork vice or bench mounted quick release mount.
2. Place the star nut into the fork tube with the concave
side(s) (B) facing up. See Fig. 2.
3. Slide the large opening of the collar over the steerer
tube and star nut. The outer ridge of the collar is seat-
ed on the top of the steerer tube. See Fig. 3.
3. Slide the driver into the top of the collar slowly so
that the driver pin locates in the threaded hole of the
star nut.
4. Hold the collar and fork and carefully drive the star
nut to the specified depth by tapping the driver with a
hammer. See Fig. 3.
For 25mm depth, stop driving when the groove (a) on
the driver shaft meet the top of the collar.
For 40mm depth, drive until the driver head contacts
the top of the collar.
5. Remove the driver and collar from the steerer tube.
CAUTION : Do not drive the nut by placing the fork
on the floor, you can damage the dropouts.
CAUTION : Using the wrong star nut for the fork or driving it in backwards or
to an incorrect depth can severely damage the fork. Always consult the
fork/headset manufacturer's instructions. For information on Cannondale
