The faucet is so simple that it would be more difficult to decipher a picture than to fix the faucet. Remove the screw, remove the handle, unscrew the nut holding the stem, pull the stem out after making a note on which side the raised plastic handle stop is, remove the rubber "seat" and spring. Then install a new seat and spring and push the new stem into the hole the same way the old one came out, and put everything back together.
