998s Refurb

Discussion in 'Builds & Projects' started by West Cork Paul, May 24, 2020.

  1. I can't remember which way Paul but I do remember thinking this thing has to break when I stripped my 998s there tight

  2. You can see the clips on the underside of the airbox if you shine a light via the LH side. Hope you understand. Clockwise to remove is oké as far as I can remember.

  3. Gteen o ring on the shoulder as I remember :upyeah:
     
  4. Anti clockwise to remove. Make sure you put a smear of red rubber grease over both the O rings inside the throttle bodies when refitting. Don’t split them as they are a tenner a piece.
    And the O ring in the recess on the fuel pump base A bit of red rubber grease over the O ring and job’s a good un.

  5. I’m still confused as to where the big green o- ring sits, on the base of the flange marked ‘Or Here’ in the last pic of post #125 above or or the in ridge above that marked ‘Here’.

    The reason I’m unsure is it’s a loose fit when I’m the ridge marked ‘here’ but has to be stretched slightly to fit the base marked ‘or here’ but an attempt to fit it earlier proved difficult when in that position and I don’t want to break it or not have a seal. TIA
     
  6. Where the number 23 is showing the O ring in the coloured diagram.

  8. Thank you, clear now :upyeah:
     
  9. It is a bastard to get back in. I used some bolts to pull the whole assembly slowly back in rather than trying to push it as it's so difficult to keep square and it tries to squish out. I now use 90 shore hardness viton O-rings instead of the 75 hardness rings that are standard. Helps a little.

  10. Grease it up and wind it in - feck knows what to do with your o-ring though o_O

  11. Just so you know Paul, mine popped out easily and went back in with little effort and no leaks to boot. Just thought I would let you know before the 17 page fuel tank o ring thread kicks off :p:D

  12. It always pays to have a few spare, never had the need to use more than one though. O rings 008.JPG

  13. Useful photo Steve, thanks :upyeah: I bet they're cheaper than getting them from the Ducati dealer.
     
  14. I think that lot with a tube of o-ring specific grease came to £14 delivered, a few years back.

  15. Just for a heads up, the best way to get the pump plate back into the bottom of the tank without any issues is to use bolts to gently pull the whole assmbly into place and a good smear of red rubber grease
     
  16. What news from Cork? How’s it coming on Paul?
     
  17. He's just taking the sprocket cover off a sucking through his teeth.:confused:

  18. Hmmm, been busy lately:(. I’m scheduled to attack it again tomorrow, that’s the plan anyway. The misfire was on the front cylinder so I had to order some new spark plugs, will swap that first and see how it goes, if not then track back to the coil and so on. Hopefully it’s just the plug breaking down:):upyeah:.

    After that, I then need to work out why the injectors dont fire sometimes :(.

    Still, it’s got a nice new fuel filter now and all the hoses inside the tank are still fit for purpose:upyeah:. The old filter was dated 17.02.04:astonished:

  19. I actually haven’t removed that yet. I might do that tomorrow now as well and see what lies beneath :eek:
