Fork Seals

[thunderpantz]

My left seal has developed a slight leak, not much at all but now i know it's there I want to sort it.


Any magical fixes, or anyone fancy 'helping' replace the seals and oil












(I use the term 'helping' loosely. I'm useless, you'll be mainly doing)

Had a big problem with mine which took ages to fix so hopefully yours is only a "weep" rather than leaking.


First thing you can do is check the stanchions (shiny tube part) for pitting or damage as this was the cause of my leak. Next, you can remove the dust seal carefully using a blunt flat screwdriver and thoroughly clean underneath it and around the stanchion making sure they're completely dry. Then take a small feeler gauge or flexible piece of thin plastic like some business cards you can get and gently slide it down past the fork oil seal and "file" the tool all the way around the seal to try and dislodge any dirt that may have built up and gotten past the seal. After that, refit the dust seal and take the bike for a good long ride. Check the state of the fork, if it is leaking then the seal is likely going to need replacing. There may still be a little oil on the stanchion even if this has fixed the problem, so it's better to keep wiping after each ride and judge it after a week or so of use, hopefully by then you wont have to wipe the oil anymore and the leak will be fixed.


If it's still leaking badly, then replacing the seals is not as hard a job as it initially seems, make sure you use OEM seals though and if you have any spare cash you may as well replace the bushes whilst you are there. If you don't have one, then get a haynes manual for the bike.


This video is excellent too, watch it at least 2 times before even starting the fix and then have it handy whilst you are working.

This is also a really good walk through somebody from the old site has made:

You can buy OEM fork parts on this website

All of that helped me, I also put in some new 15w fork oil rather than the 10w standard and honestly even with the original springs the bike handles really good in my opinion, better than before with the old forks in the state they were in so it would be worth doing. Although if you weigh less than 12 stone it can be a bit too stiff apparently, I'm just over 13 in textile stuff and it can be a bit stiff at times but worth it for the handling benefit. Hope that helps a bit anyway

Check for stone chips on the stanchions, sharp edges act like a knife and muller seals.
If they leak just replace, and get rid of any raised edges.

go on ebay and search "seal mate" it might be worth a try?

I've used clear nail varnish on corrosion pits before, make sure it's thoroughly degreased first and put a blob on, when dry put another blob on till filled and carefully clean over, stops it ripping out a new seal.
