This week, I decided to thinker some more and overhaul my Brompton's 3 speed SA hub. First was to remove the rear wheel. To do this, follow the instruction from brompton (youtube) and it is straight forward.
After getting the rear wheel out, I started removing the nuts and cones from both ends, then the ballring cap that holds the mechanism inside. It would require to do some hammering, just use your rubber or wooden mallet and a screw driver. After removing the cap, you can see the axle going inside with clutch, springs and all those parts greased inside. Remember to remember how each part are placed in sequence. Used kerosene to clean and remove those old grease, dried them up and put them back together. Greased it with teflon grease and everything seems smooth and clean. When putting it back together, one tip is to put back the puller chain first to hold the small piece of metal that pulls the clutch.
