Left Fork Leaking Oil

Question I want to start off by thanking you for the Fix My Hog “Touring Edition” DVD. The video is full of helpful tips on how to perform many maintenance tasks on my Harley-Davidson. The problem I am having is my 2001 FLHPI Road King left fork leaking oil, so I am in the process of removing my front forks to replace all the seals and gaskets with an after-market kit. I have followed the Harley shop manual and your video on how to remove the forks. Unfortunately, our attempts to remove the fork slider from the fork tube have met with considerable resistance. Using the fork slider like a slide hammer in the removal process has been nothing but troublesome and the seals have not moved a fraction of an inch. I suspect the seals have not been replaced since the bike was first built at the factory. Do you have any suggestions? – Kim

Answer Hi Kim, Use a 1/8 drill bit in a 90 degree drill and drill a bunch of holes through the seal and see if that loosens it up. Make sure not to damage the fork tube. Take your time and cover it with duct tape and drill straight. If this does not loosen it up, you can also use a slide hammer in the 1/8 inch holes. I have also used a dermal tool before. Use whatever is available. The point is to cut the seal so that it can be grabbed and pulled out. Be aware that there is a hardened steel washer under the seal.

    I am ready to replace and up grade the front assembly on my 2006flhp. What products do you recommend. I watched your front tube replacement vid and feel confident I can do this

    Ticket 18825 What a coincidence. I got my 08 1200Classic Sportster out today for a ride. Been raining for a month. Anyway, I made it about 2 miles and oil pouring out of my Left fork. Can’t tell exactly where from. seems to be down low around brake assembly. Any suggestions. ?? I will begin disassembly tomorrow to replace all seals and such. Thanks., Old Hippy

      Dear Ralph,

      Thank you for your patience. In regards to your question-

      You will need to replace your fork seals.
      We also suggest replacing the upper and lower bushings.
      When the assembly is apart, closely inspect the fork tubes. If there is a lot of surface wear lines, there is a goid chance that the tubes will also need replacement in order for the assembly to seal.
