Triumph Tr7 Sticking Clutch Issue

I assume you have changed the oil, if not that may help.

Never seen one with those pads and suspect someone has added them. Why now convert to the 7 plate clutch. And the racing boys have an additive they use for clutches but i have forgot what its called now.

I had the same issue, I tried all manner of different things in order to alleviate the problem, in the end I "bit the bullet" so to speak and bought a complete clutch from SRM, not cheap at almost £600, however it solved the issue and was a 1 finger clutch operating lever from then onwards. One issue with the old clutch was condensation from being laid up for a few weeks, this stuck the plates and in turn caused gear change issues, after scores of times stripping and re assembling the clutch I had enough hence the SRM clutch purchase. I also went for ATF fluid in the chain-case.

 

You know chaps the triumph clutch is classed as a dry plate clutch and the oil is in fact only to lubricate the chain. So don't over fill.

Sure no dispute or argument this side. You will get it eventually and you bike will be fantastic. Do hit the upload a file button bottom right corner and show of the beastie here in the asylum.

From 1981 onwards Triumph tried to reduce the pull required on the clutch by using a 7 plate system. The friction plate thickness were reduced to allow the additional plate so to give extra friction they stuck the friction surfaces on the inside of the clutch basket - like yours Keve.
Spares for these are pretty hard to find these days.
Rather than try to boil, clean, straighten what you have, go get yourself a new clutch basket and new clutch plates, you'll need a whole set, including the plain plates. But you should be ok using the centre, pressure plate, rod etc. Go for one of the new type 7 plate set ups as they aren't an awful lot dearer than the traditional 6 plate. You can then use the 650 springs.
Soak it all in oil overnight and whack it all in (get one of the nice new shiny ally pressure plates as they do look sexy).
You'll be bombing around in no time.

After 1969 the oil seal between the crankcase and the primary was removed. Three small holes were also introduced to allow the oil in the primary/clutch side to 'self level' from the engine oil. Engine oil therefore lubricates the primary chain and the clutch so no need for anything other than engine oil in the primary side. Over....

It sure is a lovely piece of machinery. I love it. If we were closer i would love to have it of of you. Bet its quite rare now a days.

I had a slightly different sort of TR7. Coincidentally it also had a clutch problem, in my case the problem was that you could put your foot through the floor under the pedal!
