pull up and off the fabric dispenser, remove the nut in the middle, and pull the piece off. underneath are 4 plastic things (dogs) that will just fall out. replace them (because they have little plastic things that jut out) and wear away. maneuver the piece back in place and tighten the screw back into place.
SAME JOB BY REPAIR CO. COST ME $95.00 THE FIRST TIME. WE USE HEAVY LOADS AND THE DOGS WEAR OUT AFTER A FEW YEARS. NOW I JUST CHANGE THEM MYSELF.***DID I ADD THAT I AM A WOMAN****
