next your gunna remove this backing plate. both bolts are 14mm. when you take the plate off theres a large snapring around the first spacer or disk. you can use a c-clamp to push it and and remove the c clip. once you do this it will start to pop out. i had the pump on its side so it didnt come flying out, atleast mine didnt but just have your hand ready. then there will be a spring underneath the first spacer and then another black spacer. both of these have O-rings on them that you can replace.
