I need instructions to replace fork seals on a 1988 h.d. flst.
First you must remove the windshield, front fender, headlight nachelle, and front wheel. Get everything off the front end. Then, take the top cap off of one fork tube at a time. I do this with it still in the front end just in case it's real tight. Once I get the top cap lossened and remvoved, I break the torque on the pinch bolt on the lower triple tree and remove the entire fork tube. With the tube off, I remove the spring and pour out all the oil. Make sure you look at the sping as you take it out, One end is different from the other and you want it back in the correct way. Now, with the oil and spring out, look at the lower end of the tube where the axle is held into the lower slider. You'll see a socket head bolt. This bolt takes an 8mm hex key. I use an air wrench to take this bolt out. Once you've got the bolt out, the inner fork tube will pull up and out of the lower slider. Pull off the rubber boot and there's snap ring just inside the top end of the slider. Remove this and pry out the old seal noting which direction the seal is facing. They go in with the lip facing down. Install the new seal and reassemble the fork tube. Install this tube on the bike, add the proper quantity of oil, install the spring and top cap, and retighten the pinch bolt on the lower triple tree. Then, do the other side the same way. Reassemble all parts taken off. Note: Reinstalling the top cap on some models can be pretty tough and my require a special frok spring compressor. Good Luck.
