Camshaft timing - adjust.
« on: September 01, 2014, 08:05:04 pm »
I see that the scheduled maintenance check sheet has a box for 'camshaft timing - adjust' only first 20,000 mile service, Trophy & Tiger Explorer only.

Anyone know exactly what this entails and how comes it's only done on these two models?

I take it that the camshafts are driven via a camchain and that there's a tensioner on that so what kind of adjustment are they talking about. :187:

The camshaft drive sprockets have a range of adjustment...   Just had the 20K done on my TTSE, and that was done; I talked to the 'tech' at length about it.   Special tools are required to lock the cams in position and precisely tension the cam chair.  The adjustment bolts are loosened so the sprockets can move to their proper position, then locked down.

Ah thanks, now I wonder if us DIY mechanics can buy these cam lock tools?

Dude

Look on the TEX forum  :028:
Ducatiparts is doing a service manual for the engine and I think he supplies some of these type of tools  :028: :028:

Yes - You can !

I would recommend that such work is only carried out by a competent mechanic,
and only after any warranty has expired !

Triumph will sell you the Service Manual for about £80.00.

Section 3 covers the Cylinder Head, which states that the following Service tools will be required :

Crankshaft Timing Pin         ( Triumph Part No. T3880601 / World of Triumph Part No. PFKL2152173 ) - Cost = £8.22
Camshaft Timing Plate        ( Triumph Part No. T3880640 / World of Triumph Part No. PFKL2304692 ) - Cost = £25.64
Camshaft Timing Tensioner ( Triumph Part No. T3880607 / World of Triumph Part No. PFKL2152179 ) - Cost = £25.43
Torque Limiter                     ( Triumph Part No. T3880609 / World of Triumph Part No. PFKL2152181 ) - Cost = £154.02

TOTAL Cost ( including the Service Manual ) = approximately £295.00 !

The Service Manual, and Service tools are available to order from your Triumph Dealer,
or on-line here : World of Triumph :028:

I wonder if this is why some cam chains rattle on start up and some dont. The ones that dont have had more slack adjusted out of them in this procedure.

Interesting supposition. I haven't had the 20K mile service done, but I have had the head replacement.  I'd assume they do this alignment when they replace the head.

I still think there is something wrong with the bikes that have cam chain tensioner noise at start.  Either that or the ones that don't make noise have an issue.  It can't be both ways.
