Replaced the FD seal on my friend's bike: Starting, you can see the dust built up on his weeping seal. Not bad yet, but while I am working on it. Use a small screwdriver to lift the seal cover. You may have to add a larger one next to it if you small one flexes too much. Just pry against the dust cover. They are tough, but easy to get off. Using a small screwdriver, pry near the end of the snap ring. Pry on the outer edge of the ring towards the center. Once you get it started it pops out easily. Use a center punch, I like snap punches, to start dimple your seal flange for drilling. I find it makes it easier to find the punch mark through the rubber if you start in one of the convenient dimples on the flat. Drill using a small drill, just smaller than the sheet metal screw you plan to put into it. Once the drill pops through immediately stop pushing. You do not want to damage the bearing. I drilled top and bottom, as sometimes you need to pull on both. In this case I screwed in a sheet metal screw, gave it a tug, and the seal came right out, so I didn't need to use the second screw. Push the new seal in as far as you can, then use the old seal to tap the new seal in to seat. The old seal will not get stuck. Make ture you seat the new one evenly until it stops. Verify it is in good by looking at the clip groove and verifying it is even all the way around, and leaves room for the clip. Snap the new ring in. Make sure it is seated all the way. Place the dust cover in place and tap it in with the palm of your hand. I had previously replaced the balancer seal and the clutch, then did a full 36K service on it, then washed it and set it aside for him to come pick up. Finally, I cleaned the garage in prep for the tech day next weekend.
