12. With the open end of the wheel facing up, fill
the area inside the wheel around the axle full of
general-purpose grease.
13. Insert the second bearing and new seal into the
wheel.
14. Apply a thread-locking adhesive to the second
spacer nut, and thread it onto the axle with the
wrench flats facing outward.
15. Torque the nut to 8 to 9 N∙m (75 to 80 in-lb),
loosen, then torque to 2 to 3 N∙m (20 to 25 in-lb).
Note:
Ensure that the axle does not extend
beyond the nut.
16. Install the seal guards over the wheel hub, and
insert wheel into the caster fork.
17. 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 adhesive.
