My husband removed the old hinge, by taking out the old screws and the old hinge and attached the new one, by inserting the new hinge and the new screws. It was as easy as 123.
Took out the screws(8mm). Used pliers to close new hinges. Re-installed the screws with as large washers as would fit(to hopefully prevent the hinges from cracking at the screw holes like the originals did). I like this supplier, part was easy to find, correct part, shipped fast, price was good.
Remove the 6 screws with a 5/16 inch nut driver. Make sure the lid gasket is in full contact all the way around. Remove any ice interfering with the lid gasket mating properly. Install new hinge using the original screws. Have somebody hold up the lid and tighten the spring nut with a deep 1/2 inch socket gradually until the lid stays up by itself.
