I also have a 1911 with a 2 piece guide rod.....I put Loctite on the rod because I didn't like it getting loose.......Anyway the pistol will break down as normal to start with by removing the slide stop, Make sure the hammer is down, Then remove the whole slide carefully forward - Barrel bushing, Spring cap, Guide rod and all.
It takes a little patience and care to get the hang of it and reassembling the pistol in same manner.
EDIT : I don't know anything about the Wafer/Washer.
