    Just browsing through the service dats, that time again..... and I noticed this. Is this saying that the Camshaft Sprocket bolt should be replaced at 20k miles or torqued at 20k miles?

    Good Day,

    I am not an expert so keep this in mind. Page 80 of the service manual part of it is attached, mentions that these 4 bolts are not to be reused during the service to adjust the timing. This service is mentioned in the schedule "Camshaft timing — adjust - only first 20,000 mile (32,000 km) service". Someone with more knowledge will correct me but I do think during this scheduled service they would replace the 4 bolts.

    Etitanic,

    Page 80 of the service manual part of it is attached, mentions that these 4 bolts
    are not to be reused during the service to adjust the timing.

    and

    I do think during this scheduled service they would replace the 4 bolts.

    It actually says that you should use them up until the point when the timing adjustment procedure
    has been completed, and then they should then be replaced - at the final tightening stage  :028:

    Thanks Coconut, that makes sense, well for modern bikes... never had to replace bolts in the good old days  :745:
    I suspect that they will have a locking compound pre applied to the new bolts..... Triumph don't trust their "technicians" to apply some thread loc on their own.....

    I haven't touched them so they can stay as is.

    Are you planning on checking the cam chain tension yourself? Have you bought the 'special tool' or do you know where you can hire one from possibly??

    Just planning the annual oil change, I won't be going into the valves so no need for bolts, was just curious that they were mentioned for replacement at 20k.
    I've told the story before but my 2013 has 23k on it now, I didn't do the valves at 20k because it has had the cylinder head recall, about 6k miles ago. I contacted Triumph to ask why I should... they said leave it to 40k
