CASTER ASSEMBLY REPLACEMENT
1. Remove the old caster assembly.
2. Install the replacement caster and caster nut. Tighten the caster nut to 90–105 ft.–lb. with a torque wrench.
NOTE
A new caster assembly with a 3M patch does not require the application of Loctite at assembly. However,
the patch is appropriate for only one installation. If the caster is removed and reassembled for any reason,
apply Loctite 242 to two or three threads of both the bolt and caster nut and tighten to 90–105 ft.–lb. with a
torque wrench.
