Instructions for installing new bushing

Drive a screwdriver between the edge of the bushing and the inside wall of the base and pry out the old bushing. 

Apply the red glue to the outside of the new bushing, place in the base and drive it in using the supplied wooden mandrel until the top of the bushing is flush with the top of the base.
