    When you say "noticed" it sounds like a visual assessment of the chains condition. Did he measure it for wear per the service manual instruction? What condition are the chain slipper blocks?
     I did my cam timing at 26,000, and the chain was as if new.

    Yeah, I agree to not take a chance. If that thing breaks, you might have to throw the entire engine away. But I would expect the timing chain  to last well over 100,000 miles, if not the entire life of the bike. Why you have timing chain problems at 40K, I would be curious about.

    I hope the TTSE timing chains usually last at least three times that 40K.

    Go to the dealer, have him hang the chain with the recommended weight, measure the distance between the specified number of links and see for your self if the chain is worn or not. Probably not! If it is, there is some other influence causing that much wear.

    Hi mastertrophy,

    I note your comment :
    The dealer  told me  its very close to final adjustment..
    Is it possible that it's the Tensioner blade and assembly that is worn,
    rather than the chain itself ??  :084:

    Examination and / or replacement of the Cam Chain is not even mentioned in the Service Schedule,
    just to check the Valve timing, and to check and adjust Valve clearances every 20,000 miles,
    so from that information alone, it would appear to be reasonable to expect that the chain
    should last the life of the motorcycle, and certainly well beyond 40,000 miles.

    IF it is accepted that chain wear at 40,000 miles is NOT normal,
    then it makes sense to work out the cause, so that it doesn't happen again ! .....

    If it HAS worn such that it needs replacing, then possible reasons could include :

    Lack of lubrication
    Incorrect assembly
    Incorrectly machined Sprocket(s)
    Faulty chain assembly or materials ( e.g. metal too soft / not hardened correctly )

    Whatever the cause, if it were me, I would be contacting Triumph directly,
    asking them to investigate, and to rectify the problem under warranty.


    According to the Service Manual the procedure for checking chain wear is to :

    Hang the chain wiith a 13Kg weight on it, and measure the distance
    between 23 links of the chain - measuring between the centres of the link pins.

    The maximum permissible specified length is 150.14mm

    NOTE that this only checks for wear in the length of the chain,
    which should also be visually examined and checked for :

    • Severe wear of any of the outer plates' contact-points
      with the sprocket teeth, and other parts of the chain
    • Signs of stiffness or kinking.

    If any of these are found then the camshaft chain should be replaced.

    Cheers  :821:
