spacer nut and thread onto the axle
with the wrench flats facing outward.
m) Torque the nut to 75-80 in-lbs. (8-9 N-m), loosen, then re-torque to 20-25
in-lbs. (2-3 N-m). Make sure axle does not extend beyond either nut.
n) Re-install the seal guards over the wheel hub and insert wheel into caster
fork. Re-install 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

adjust torque on spacer nut until there is a slight amount of drag. Re-apply
threadlocking adhesive.
