It seems they've changed the bolts in addition to the Cam cover, seals & gasket:-

Interestingly, being ignorant of the cam cover and bolt changes, I've used the new gasket & seals on my 2008 T100 without any problem whatsoever so the changes to those items must be very subtle.

These are the items to look out for if you are plagued by leaks:

The Sealing washer T1260337 rather than the old T1260309.

The Cam cover gasket T1260904 rather than the old T1260900
I have a 2005 Thruxton with Carbs. Two different Triumph dealers could NOT get their head around these new part numbers. They said that these part numbers listed are part of a kit that goes with chromed valve covers... ??

So I come to the great ones here at Triumphrat... will these two new part numbers work for my 2005 Thruxton ?

Thanks.

I had a weepy cam cover, so I ordered a new one from Hermys. Also bought new washers, installed and torqued to specs, good to go. Not sure if it is the old or the new, but it doesn't leak anymore. This was about 3 months ago.

And I have a chrome valve cover that did come with a new gasket already on the cover and a little bag with 4 new screws and seals.
No separate parts listing though.

We'll FYI, I used the listed newer parts numbers as listed near the beginning of this thread and did this to my 2005 thruxton. Works great no weepage. I torqued the four cover bolts to 12 NM which is the middle of what the Haynes manual lists at 10 NM and the new updated value if 14 NM I heard about here.

Also used the British Customs AI Delete kit at the same time.

Both things were pretty simple for me who barely turns a screwdriver. I don't know what we did before YouTube. I like Delboys Garage series, pretty down to earth knowledge he passes on with an English flair. I chuckle every time he says "spanner" ...

Thanks for confirmation that the updated parts work on the older models.

This is killing me. :-) I literally went to my loathesome area Triumph dealer yesterday to procure a valve cover gasket, and now this thread shows up and I simply cannot make heads or tails of whether or not I have the right bloody gasket.

My scenario is this: I have a 2007 T-100 w/ the chrome valve cover on it (put on by the last owner). The dealer gave me a #900 gasket without knowing that I had the chrome valve cover. Should I infer from what I've read here that I should now go back to them and request a #904 gasket to compliment this valve cover?

Your collective insights, as always, are appreciated.

If you're wary of fitting the newer parts on your older bike just ask for the old part numbers:

Sealing washer T1260309

Cam cover gasket T1260900
