Crack In Lower Fork Clamp

  1. I thought I'd give the old girl a bit of a clean today and take the fairing off.
    To my surprise and horror I found that the lower fork clamp had cracked near the pinch bolts. Typical sign of overtightening, may be, I had the forks out a number of years ago. The question is finding a replacement is proving challenging to say the least, so would one from the i.e. fit?
    Thanks
     
  2. Hi, I might have one.
     
  3. That would be very good if you have one count message me with your price if you do have one
     
  4. If you need a hand, I can assist you, just let me know :upyeah:
     
  5. Slight problem trying to buy from the site. It only seems to allow French buyers, it wont set up an account with a uk phone number. Do you have an account already so that you can aquire it on my behalf?
     
  6. I don't mind sorting this for you at cost, I'll ask the seller if it is still available...we can switch to DM...

  9. With this issue I now have the oppertunity to install tapered roller bearings. Does anyone have any information on any particular manufacturer to go for?
     
  10. Check your PM's
     
  11. SKF or Timken

    Cheers Gaz
     
  12. If you are talking 900SS I think it this, but please check sizes before purchase.

    If you have an "Acorn Industrial Services" near I found them to be reasonable. I bought one from a car parts web site and when it came I thought it look suspect. The etching and finish did not look up to the usual SKF standard, so buy from reputable supplier.

    Cheers Gaz

  13. I have seen a number of trading standards warnings about “fake”/cheap copy bearings being offered on the internet. I used to use a local supplier but some of the bearings have been designated “automotive” by the manufacturer so no longer available to some resellers. There is a French company who come recommended but for the life of me, can’t find a link. Andy
     
  14. So here's the SKF I had in my headstock 16856314661975196439046510511967.jpg
     
  15. Only the outer race shown here, obviously
     
  16. A lot of people use 123roulement over here («roulement» being the French for «bearing»).
