❶ Loosen the top cap bolt and remove the top cap.
Important!
Do not
disassemble the headset or loosen any
parts. Be sure the end of the fork is on the ground or being
held with your free hand, because once you loosen the top
cap the fork assembly may fall out of the frame.

❷ Check that the gap between the top of the steerer tube and
top of the stem is between 3 - 5 mm (1/8" - 3/16").
Figure 4.41
If the gap is not correct add or remove spacers until it is.
The stem needs to press down on the spacers in order to
adjust the bearings. If the gap is correct then re-install the
top cap and tighten the top cap bolt until it is snug.
Do not
over tighten.
❸ Slightly loosen the stem pinch bolts. The stem probably
won't move but make sure the stem remains aligned with
the fork and wheel.
❹ Re-install and tighten the top cap down with a 1/4 to 1/2
turn of the top cap screw and test for shakiness in the
headset. If there is still play in the headset then turn the top
cap bolt another 1/4 to 1/2 turn. Repeat this process until
the shakiness is gone.
❺ Lift up the front wheel of the bicycle, if the wheel does not
move freely left to right the top cap bolt is too tight. If this is
the case turn the top cap bolt back some.
❻ Repeat steps 3 and 4 until there is no play in the headset.
If the play in the headset cannot be rectified with these
adjustments see a qualified bicycle mechanic for these
repairs.
