6. Pack the bearings with a NGLI grade #1
multi-purpose grease.
7. Insert one bearing, one new seal into the wheel.
Note: Seals (Exmark P/N 103-0063) must be
replaced.
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 ats facing outward. Do
Not thread spacer nut all of the way onto the end
of the axle. Leave approximately 1/8 inch (3 mm)
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, ll
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 ats
facing outward.
13. Torque the nut to 75-80 in-lb (8-9 N-m), loosen,
then re-torque to 20-25 in-lb (2-3 N-m). 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 tire should not spin freely
(more than 1 or 2 revolutions) or have any side
play. If the wheel spins freely, adjust torque on
spacer nut until there is a slight amount of drag.
