    This type of spanner works if you really want to torque the nut (bearing in mind the correct orientation with a torque spanner), but i normally just do it by hand.
    And I always fit new lock nuts

  2. Yes will just do it by hand... old belts removed, will fit the new ones next weekend when back from Finland

  4. What is that actually called? I can see it's a derivative of a crowsfoot, but does it have any particular name?

    Thanks
     
  5. Crowsfoot ring spanner i think.
    Google Laser 7286
     
  6. Torque adapter.
     
  7. Hi Jamie, very very important to turn the eccentric Belt Tensioner Pulley ANTI CLOCKWISE to tension the belt. (It is an easy error to turn it clockwise, in which case due to the geometry, the belts end up running too close to each other)

  8. Noted thanks!

    Well its beat me tonight, so had to walk away and try it another day when my patiences has returned... can't for the life of me get the pully back on with the new belt in place and also vice versa, if I leave the pully on and then try to fit the belt, u can't get it over the last cam
     
  9. Pre-fit the belt over the pulley whilst just on the cam pulleys and slide everything on together, it's tight but with the right technique not too bad.

    If the 'springy' camshaft (vertical cylinder) is making it harder, do it in a different position, a few teeth back, just make sure it's the correct position once fitted.
     
  10. Right after a battle the new belts are on the bike. Was quite tough, maybe need some stronger muscles

    So next questions, maybe im panicking about nothing. All the dots line up, but when I slowly turn the wheel, I hear what sounds like a ping on every rotation. Can't remember hearing this before... I could do a youtube video and share on here if that helps

    Also what is the best app yo test the tensioning, and any tips would be great.

    Cheers jamie
     
  11. Had a friend who builds engines pop round and all is fine with the bike, timing is spot on and tensioned now.. now time to rebuild it back up...

    Next job oil and filter change
