8. Install the axle nut and tighten with the wrench until it comes into contact with the
wheel bearing. At this point the wrench will not want to turn any further with
minimal force. Turn the wrench an additional 1/16 to 1/8 of a turn to place a preload
on the wheel bearing. On the standard cast mag wheel, this is ½ to ¼ the distance
between two spokes.
9. Spin the wheel to insure that it spins freely and does not stop abruptly. If the wheel
stops abruptly, the axle nut is too tight. Grab the top of the wheel and attempt to
move it in and out, to check for lateral play. If the wheel exhibits lateral play, the
axle nut is too loose.
WARNING:
DO NOT APPLY EXCESS
PRELOAD
. EXCESS TORQUE WILL
RESULT IN WHEEL BEARING FAILURE. THE WHEEL MUST
NEVER
HAVE
ANY LATERAL MOVEMENT.
10. Reinstall hub covers. Refer to section regarding hub cover for installation
instructions according to wheel type.
