OK so on previous spanner nights we've had the forks out and opened up for various reasons including replacing the oil. Now it's time to take those suckers apart to replace fork seals. (See what I did there? WAAAAA I kill me.) Forks are full of oil, and operate as two tubes, one sliding inside the other. The fork seals are there to keep the fork's damping oil from squirting out of the fork when it's compressed. Sometimes, due to age, wheelie abuse, or pitted fork tubes rubbing against the rubber seals, they deteriorate to a point where the seals begin leaking oil. That's when you've got to replace them. To check if your fork seals need to be replaced, just run your finger around the inner fork tube right where it goes into the outer tube. If it's oily, congratulations! You need new seals. The important bits of a fork seal are the dust cover, the wire ring clip, the oil seal, and the inner and outer metal bushes. Fingers crossed, all we'll need to replace this week is the oil seal. Our project bike this week is Nee's Hornet 250. It has right-way-up forks (cartridge style I believe) which will make life a bit easier for us because they don't need as much dismantling as USDs. It's got a leaky right front fork seal, but we'll replace both. The only special tools we'll need per se are whatever it takes to get the front wheel off, a jack to hold the front end off the ground, and something to pound the new fork seal back in with. On Nam's advice we'll try using the old seal as a driver to seat the new one. Venue is Nee's place in Templestowe I believe, this is to be confirmed. As usual, 7pm start. Please post in this thread if you want the address, all are welcome.
