Change fork seals
you need to undo the pinch bolts on the yolks and remove the front wheel & mudguard. Undo the bolys retaining the brake caliper and swing it towards the frame downtube, secure it with string.
Withdraw each fork leg and clean up with a soft rag.
On each leg, remove the top bolt (slowly to release spring pressure) and pour out the fork oil and discard it. Pour in a small amount of parrafin and swill it around a bit to clean out any residue.
Remove the dustcap or gaiter and put it on one side.
You will now see the fork oil seal. If it has a circlip then remove it, if not, then don't bother.
Prise out old seal carefully making sure not to mark the soft alloy of the lower leg or the chrome on the stantion.
Rub a little fork oil onto the new seal and carefully slide it over the stantion, pushing it all the way down.
Use a piece of wood to firmly push the seal into the lower leg until it sits squarely and fully into place.
Replace circlip if necessary and refit dust cover.
Refill each fork leg with 142 ml of 10 wieght fork oil and replace top bolt.
pump the leg a few times to settle the oil and then refit the legs in the reverse order of removal.
When done, pump the forks a few times, go for a cuppa whilst it settles and then you are all ready to go.
