Electrician's pliers, long nose pliers, brake pliers and snap ring (or circlip) pliers.
Remove the ball and pull it out. If it's a closed in ball, take some needlenose pliers, put the end of the pliers in the ring and gently pull the pliers open inside the ring until the ball pops out. Be sure to do this somewhere where the ball doesn't bounce off under something. Edit: If its a ball closure ring, use needlenose pliers. I didnt have needlenose pliers so my dad did it with scissors for me, wasnt a brillaint idea but it did work (:
Ring.
Use Snap Ring Pliers on the clips (3) - squeeze pliers closed and while clip is spread open pull up with needle nose pliers
ring groove cleaner (if needed) and piston ring pliers (can just use your hand or needle nose)
There shouldn't be a back piece.... You should either have a hoop( segment ring or CBR) or a nose screw. Neither of which have a back piece
If it is a captive belly ring you may go to the place you got it peirced and let them take it out for you, or.... you can do what i did, be very careful and take sizzorz gently try to cut the top of the ring near the ball. My flew off. Then steralize the new ring with soap and put it in. Good to go! A piercer will use ring closing pliers. You don't have any. Get a pair of needle-nose pliers and wrap the tips in electrical tape. You will probably also need a taper. First be sure it's healed. If the ring won't turn freely it's not ready to be changed. Use the pliers to spread the ring a bit--put the pliers in the ring and spread them a bit. Set the ball aside. Remove the ring from the piercing. If you have a taper, lubricate it and work it into the piercing. Put the end of the new ring into the taper and pull it gently through the piercing. When the taper's all the way out of your piercing, the ring will be in. Put the ball between the tips of the new ring and squeeze it closed with the pliers. If this new jewelry is a curved barbell, once it's in just screw the ball on.
Hog ring pliers can be purchased on the internet or at your local hardware store. The biggest range of hog ring pliers and best prices seem to be on Amazon.
