Lubricating the Caster Wheel Hubs (2500 Series Machines Only) (Cont.)
NOTE: Do not thread the spacer nut all the way onto the end of the axle. Leave approximately 1/8 in. (3
mm) 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 with the new seal and bearing.
11. With the open end of the wheel facing up, ll 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 compound to the second spacer nut and thread it onto the axle with the wrench ats
facing outward.
14. Torque the nut to 75-80 in-lbs. (8-9 Nm), loosen the nut, then torque to 20-25 in-lbs. (2-3 Nm).
NOTE: Make sure 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.
16. Install the caster bolt and tighten the nut fully.
NOTE: To prevent seal and bearing damaged, check the bearing adjustment often. Spin the caster tire.
The tire should not spin freely (more than one or two 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 compound.
