Want to change fork seals - FLHTCUI Electra Glide Ultra Classic Harley Davidson Motorcycles

Without knowing what year and model bike you're working on, I'll have to be "general" in my explanation. To change the fork seals, you must either take the upper and lower fork tube assembly out of the triple trees or be able to lift the bike at least 12 inches off the floor. Once you havef drained the tube by removing the small screw in the trailing side of the slider and worked the fork oil out, taken the front wheel off, the front caliper(s) off and the fender or removed the forks from the triple trees, look at the bottom end of the slider (lower fork). You'll see a special socket head bolt in a recess under there. It takes a 6mm allen wrench or hex key to remove the bolt. It is designed to take a special "piloted" key but you can get it out with a NEW hex key. I prefer one of the hex key sockets that will fit onto an air wrench. It works a lot better. Take the bolt out and the slider comes off the bottom end of the upper tube. Take the rubber boot off the slider, the retainer ring and pry the seal out.

Good Luck
