14. Torque the nut to 8 to 9 N∙m (75 to 80 in-lb), loosen
the nut, then torque it to 2 to 3 N∙m (20 to 25 in-lb).
Note: Make sure that the axle does not extend beyond
either nut.
15. Install the seal guards over the wheel hub and insert
wheel into the caster fork.
16. Install the caster bolt and tighten the nut fully.
Important: To prevent seal and bearing damage, check
the bearing adjustment often. Spin the caster tire. The
tire should not spin freely (more than 1 or 2 revolutions)
or have any side play. If the wheel spins freely, adjust the
torque on the spacer nut until there is a slight amount of
drag. Apply another layer of thread-locking compound.
