    Cam Chain Tensioner Tool
    on: Dec 14, 2021, 02.53 am
    Dec 14, 2021, 02.53 am
    I plan on checking valve clearances this winter.  I've done valve clearances before on other bikes and I've got that figured out.  I got interested in the cam timing once I found out that was required at 20k miles.  I've read through the service manual several times and looked at the info on the forum.  The manual states that the cam tensioner tool is set to 0.6 nm which is equal to 5 inch pounds of torque. In the thread that I followed on the forum someone repeatedly states that he set 6nm on the tensioner.  I just wanted to be sure that the correct torque is 0.6nm.  Is this true?

    Hi Trophyed-Up,

    I cannot give you a 100% definite answer, but I'm 99% sure the correct figure is 0.6Nm.

    If this is the Topic you refer to : Timing Chain Top Pad rubbing the chain
    it does quote 6 Nm - for a Tool purchased from eBay !  :015:

    This Topic : Camshaft timing - adjust has a post by Member azccj showing the Tool,
    which was supplied with a Calibration Certificate for 0.6Nm, as per the information
    in the official Service Manual, and many other Forum Topics on this subject.  :028:

    Cheers  :821:

    Thanks.  I was pretty sure 0.6nm was the correct number.  I find it a little hard to believe that the tensioner adjustment could have that much affect on cam timing.  I've found a torque limit tool on Amazon to do this procedure.   The cam timing plate from Triumph is a must.  Unless the cam tensioner completely failed and caused the cam chain to jump a link I don't see how the exact tension would be so important.  Over time the tensioner might get weaker but you still have hydraulic pressure on the tensioner.  From what I've read the service manual only recommends the cam timing check at the 20k service. I'm guessing that if the cam chain is going to stretch it happens over the first 20k miles.  If the tensioner could affect cam timing as much as the service manual implies then why isn't it more important to check as time and mileage pile up?

    The information in the official Triumph Service Manual relating to the
    Camshaft Timing Check and Adjustment interval HAS been changed
    from the first 20,000 miles only, to EVERY 20,000 miles.

    This alteration, along with all the other known errors and omissions ( and there are several ! )
    for the Service Manual, Owners Handbook, Owners Service Handbook and Owners Audio Handbook,
    can be found in downloadable documents within this Topic :

    Owners, Audio, and Service Handbooks + Service Manual errata

    I recommend that EVERY Trophy Owner downloads these documents,
    and uses them to update their own Triumph Publications,
    ESPECIALLY those who use the Service Manual.  :169:

    Cheers  :821:

    I had looked through that awhile back.  Maybe I missed that one.  You can't beat the Trophy forum for good info.

    It is defenetley 0.6 nm you can buy a cheaper tool for checking the torque that is a lot cheaper than the triumph tool .it is very important and puts the chain under the correct tention for sprocket adjust ments inlet and exhaust .
    I would also recommend replacement of the tentioner to the latest one and check the timing chain lenth at this stage also .
    Every 20 k is check and adjust as the timing chains stretch a lot cheap chain comes to mind . Please look at the ammendments to the manual in the forum so you don't use the 8mm bolt to turn the crankshaft in error ..?

    I found  a torque limiter on Amazon.  It's TorQ-Armour and the one I got is 5 inch pounds.  It comes with a calibration certificate for what that's worth.  Think I paid $36.  I know some have recommended an inch pound torque wrench but I have doubts about accuracy when the wrench is 1 to 20 nm and you need 0.6 nm.

    According to this On-Line conversion site :

    Convert Nm to Ft lbs

    .... 0.6 Nm is equal to 0.4425 Ft lbs.

    Don't go using a 5.0 Ft lbs Limiter ( or the 15.0 Ft lbs one in the Photo )
    to set the Camshaft Timing Tensioner !  :005:
