1. Seal guard
2. Remove caster wheel from caster forks.
3. Remove seal guards from the wheel hub.
4. Remove one of the spacer nuts from the axle assembly
in the caster wheel. Note that thread locking adhesive
has been applied to lock the spacer nuts to the axle.
Remove the axle (with the other spacer nut still
assembled to it) from the wheel assembly.
5. Pry out seals, and inspect bearings for wear or damage
and replace if necessary.
6. Pack the bearings with a NGLI grade #1 multi-purpose
grease.
7. Insert one bearing, one new seal into the wheel.
Note: Replace the seals, part number 103-0063.
8. If the axle assembly has had both spacer nuts removed
(or broken loose), apply a thread locking adhesive
to one spacer nut and thread onto the axle with the
wrench flats facing outward. Do not thread 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.
9. Insert the assembled nut and axle into the wheel on the
side of the wheel with the new seal and bearing.
10. With the open end of the wheel facing up, fill the area
inside the wheel around the axle full of NGLI grade
#1 multi-purpose grease.
11. Insert the second bearing and new seal into the wheel.
12. Apply a thread locking adhesive to the 2nd spacer nut
and thread onto the axle with the wrench flats facing
outward.
13. Torque the nut to 8-9 N-m (75-80 in-lb), loosen, then
re-torque to 2-3 N-m (20-25 in-lb). Make sure axle
does not extend beyond either nut.
14. Reinstall the seal guards over the wheel hub and insert
wheel into caster fork. Reinstall caster bolt and tighten
nut fully.
Important: To prevent seal and bearing damage, check
the bearing adjustment often. Spin the caster tire. The
