you need to buy a free wheel removal tool wich you can get from any bike shop insert the tool and turn anti clock wise (this may require a lot of strenth or a long handled adjustable wrench to turn free wheel, when you buy the tool the bike shop can advise if you are still unsure or any bike shop should remove it for you ,but do remove the back wheel yourself and take it to the shop some shops charge more for removal from bike ,also you will need a new chain as the new free wheel will not be compatible to the old chain
