ST2 98 model clutch slave cylinder oil seal fitting 'issues'

Discussion in 'Technical Help' started by steve evans, Jul 11, 2012.

  1. Greetings,

    This might be a daft question but can anyone tell me exactly how to fit the replacement oil seal inside the slave clutch cylinder. I've been having a leaking cylinder for a while, bought a replacement seal kit and O-rings for the rod etc but can not for the life of me see how to fit the oil seal. Tried to just 'pop' it in the general area (both sides around) and tighten it all back up again but as soon as I start to fill with fluid and get pressure build up it starts to leak out of the bottom of the cylinder again. Any help will be much appreciated.

    Regards

  2. Not fitted the seals Steve, most people tend to bin the original and replace it with an Oberon one......lighter action and better looking.....
     
  3. Is that the whole cylinder? The local dealer first sold me a whole new different set up with new rod that prevents spinning etc. but the rod was a half inch too long so just went for the seal replacement. In fact I don't think I even remember seeing the old seal but it was a while ago when I took it apart as I had other problems to deal with i.e. regulator/rectifier which are finally sorted (expensive). The seal has a sort of lip on it but I can't seem to make heads or tails out of it
     
  4. As Nog said....

    Bin it and get the Oberon one. They come with a lifetime guarantee, they also come with all the bits you need too.
     
  5. Steve, a new regulator can be had for about £90 from Electrex World And you can fit it yourself in ten minutes or so......and yes, the whole slave cylinder....what on EARTH you were sold another pushrod for god alone knows........

    Your Search Results with Electrex World Ltd
     
  6. It looks like that may be the way forward then? To be fair they (Woods) gave us the money back. Re fitting the regulator in ten minutes, it took me 'hours' with all the fairing dismantling etc. Anyhow thanks for your help.
     
  7. I've just had a look at the Oberon ones, they look like a really nice bit of kit etc but they are still £90! There must be someone on here who knows how and where this seal goes in?
     
  8. There will be SOMEONE along soon who has done it Steve I'm sure.....
     

  9. There is.....it goes in the BIN :wink:, or you'll be replacing it again in a few months:frown:

  10. If it can wait until the morning, I've got a spare in the workshop and can take some pictures for you?
     
  11. Nick,

    That would be much appreciated indeed.

    cheers
     
  12. From memory, the piston has a spring behind it, is sealed with a square seal, and has a normal seal on top to hold it together, flat side outermost?
     
  13. Nick,

    Do you think that the seal goes in underneath the bearing or on top of the bearing? The seal has a form of recess in it where it looks as though it may have to fit over some form of lip, therefore, my question is do you think it fits over the piston somehow and then the bearing goes on top of this i.e. the bearing sitting on the flat side of the seal? The seal is pretty rigid and does not look as though it will fit neatly in the available space; this is why I tried to just placeit on top of the bearing. I hope that this makes sense?

  15. My mistake, the seal just stops crud from entering the piston and wearing the pushrod. I don't know what bearing you mean though? Hope these pictures help?

  16. Nick,

    Many thanks for the photos and your time, it is much appreciated indeed!
    In relation to the pictures above, what I was referring to as the bearing is the blue 'thingamibob'. However, I was also provided with a thin black circular oil seal that looks as though it is made to fit over some sort of lip on the one side and is flat on the other. What is confusing me is where this actually sits in the equation, as I can not figure out where to fit it and as previously stated I do not remember removing the original one?

    Anyhow, thanks again and I'll have another 'bash' at it tonight.
     
  17. From your description, you have the blue external oil seal, and the black piston seal. Remove the piston from the body and fit the black seal into the groove, square side out. Then lube it with brake fluid and slide it into the body, the seal then fits inside the piston, as per the last picture, hope that helps?
     
  18. Aha, that certainly does sound feasible. I don't suppose you know any tricks on how to get the piston out without damaging it? I always seem to damage things like this so any tips will really help.
     
  19. Compressed air. BUT BE Careful.
    If you have it disconnected from the bike put an air line into the hole for hose connection and carefully blow it out.
     
  20. Or simply re-connect it to the hose, a quick bleed, and pump it out with the clutch lever ;-)
