Push the faucet handle back to access the set screw. Remove the screw and lift off the handle. Remove the escutcheon cap, unscrew the disk cylinder mounting screws and lift out the cylinder.

Rinse thoroughly. Then replace the seals and reassemble the faucet. Move the handle to the "on" position and very slowly turn the water back on—the force of the returning water can fracture the ceramic disk.

If you're replacing the entire cylinder, which seldom is necessary, merely set it in place and secure it with the new mounting screws.
