Note: The seals must be replaced.
9. If the axle assembly has had both spacer nuts removed
(or broken loose), apply a thread locking adhesive to 1
spacer nut and thread it onto the axle with the wrench
flats facing outward.
Note: Do not thread the spacer nut all of the way
onto the end of the axle. Leave approximately 3 mm
(1/8 inch) from the outer surface of the spacer nut to
the end of the axle inside the nut.
10. Insert the assembled nut and axle into the wheel on the
side of the wheel with the new seal and bearing.
11. With the open end of the wheel facing up, fill the area
inside the wheel around the axle full of general-purpose
grease.
12. Insert the second bearing and new seal into the wheel.
13. Apply a thread locking adhesive 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,
then re-torque 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
the wheel into the caster fork. 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 thread locking adhesive.
