"cone wrenches" . If you do not own these tools, do
not attempt hub bearing adjustments. Have a qualified
tricycle mechanic perform the adjustment if you have
any doubts .
1 . Check to make sure neither locknut is loose .
2 . To adjust, remove wheel from tricycle and loosen
the locknut on one side of the hub while holding the
bearing cone on the same side with a cone wrench .
3 . Rotate the adjusting cone as needed to eliminate
free play .
Action

cone in position .
5 . Re-check that the wheel can turn freely without
excessive side play .
