Front Sprocket Drive - Seal

Discussion in 'Supersport (1974-2007)' started by ck_uk, Jun 4, 2019.

  1. Apologies if I've got the terminology incorrect.

    The lower part of this rubber gaitor/seal doesn't look too clever.

    Have I got a problem here, anything major to worry about before the engine goes back in the frame?

  2. Its a metal ring seal with rubber around it, so as long as the metal is secure in the hole, I would think its ok, however, although I am not 100 precent, I think you can replace these without splitting the cases. I have only done it when my engines have been apart so thats why I am not 100 percent. If it was me, I would replace it before putting it bcak in. Ill get you the sizes, its a standard SKF or equivalent seal. Get from ebay as its cheaper than Ducati.
     
  3. I have one. So here you go for sizes. Should go in without splitting cases, may be tricky pressing it into place but I would try it if it was my bike

  4. Brilliant, thanks. Is there any special trick to getting the existing one out, without splitting the cases? I haven't attempted yet.

    There seems to be a seller based in Lithuania.
     
  5. Screw a self tapper into it and use that to pull the old seal out with a pair of grips. Use a deep socket, piece of tube or a suitable box key to tap the new one in.

  6. Don't damage the bearing behind it.
     
  7. When fitting the new one, wrap some insulation tape around the splines to protect the new seal

  8. Ive tried this, think it was in Haynes manual. I found it a bit tight to get on so just resorted to grease, which works better, the edges of the splines are not sharp, as long as you inspect them first!
