12.
Insert the second bearing and new seal into the
wheel.
13.
Apply a thread-locking compound to the second
spacer nut and thread it onto the axle with the
wrench flats facing outward.
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.
