    Anyone have a Top End Rattle at start up for 2 or 3 seconds?  Not every time, just occasionally.

    Anyone done a step by step for stripping the tensioner out and checking / 're setting it? My fairings are coming off during the hols so I want to look at mine.

    HI GavJ,

    The procedures are detailed in Chapter 3 of the Service Manual.

    The full procedure is quite protracted requiring removal of the fuel tank
    to access and remove the Cylinder Head cover,
    removal of the right side crankshaft cover, rotation of the engine to TDC
    and insertion of a Service Tool to lock the engine and Camshafts in position,
    with a wedge inserted to keep tension on, and prevent movement of the chain / camshafts.

    The Cam chain tensioner can then be removed and overhauled.

    I would recommend anyone considering such a task to invest in the official
    Triumph Service Manual - available from any authorised Triumph Dealership.  :028:

    Cheers  :821:

    My understanding is that the clatter that you hear occasionally is deflated lifters.  That is what I was told at the dealer.  Once they reinflate with oil, the clatter goes away.  Again, this is what I was told when I asked the service guy at my dealer.  I've never heard that of another engine, but, they didn't seem worried about it.

    ...... deflated lifters.  That is what I was told at the dealer.

    Deflated Lifters Eh ?  :015:

    There are NO Hydraulic Valve Lifters in the Trophy engine. !

    The Valve clearances are adjusted by changing variable thickness shims
    which sit between the valve tappet bucket and the valves.
    The camshaft lobes act directly upon the valve tappet bucket.

    If the Camshaft Chain Tensioner is not holding oil pressure,
    or has been drained of oil during maintenance, then the camshaft drive chain and tensioner
    blade will be noisy until full oil pressure is felt at the tensioner plunger ( after starting the engine ).
    This could take up to 5 seconds ( Service Manual Chapter 3, Page 11, Paragraph 6 ).

    Time for a new Dealer ?

    guess so...  Like I said...  It's what he told me...  I stand corrected.

    It's not YOU that needs correcting - it's the Dealer !
