Question about Noise while releasing clutch / Clutch Jitter / judder / Grinding noise

at 10:57 you can see the judder ring inside one of the larger diameter friction plates. Then at 11:06 you see the channel where the judder ring carved a groove in one of the steel plates.


You should also check out @Protonhound's posts #178 and #180 which show the ring. He has some YouTubes, as well. As far as I know, he was the first to tear into the 2.5 clutch, for which he should be credited. It seems very few riders are willing to do much of their own work on these bikes. When I had the Roadster there was a ton of wisdom from members here who thought nothing of maintaining or modifying their bikes.
In hindsight I wish I had taken more pics/video but I can't even keep a record of my maintenance so there's that.
 
I replaced mine at 46,000 miles while doing the 40K service (a little late). The friction plates were still well within spec, but it appeared that the anti-judder ring had worn a groove into one of the plates. Given the time and effort to get to them I decided to go ahead and replace everything while in there. No more judder and definitely smoother shifting.

I did a video on the 20/40K service (valve check, valve adjustment, timing adjustment, clutch change and bleed, fuel and air filter, and spark plug renewal ).
The clutch replacement is at 10:08......

@Protonhound @Journeyman

I found the rings without the kit #7 and #8

but I am curious which steel plate to buy from the list here ? which plate would replace the grooved worn out steel plate as Protonhound showed and other riders have also found grooved steel ring , picture from another poster comparing two steel plate

Below are the plates my OEM Triumph dealer is selling separately

Can you tell me which number from the list I should buy to replace worn/grooved out steel plate?

Hmm- thought I could give you an easy answer, but there is a lot of discrepancy in the information.

- the manual states that there are 8 identical steel plates and one with a larger internal diameter. This is what I found when replacing my clutch. It is one of the 8 larger plates that has the groove.
- your schematic shows three different plates (all #9, but with different part numbers). One plate of one, six of another, and one more of the third. That's eight plates not nine. Also, none of those part numbers match the triumph numbers I found. That doesn't look like the 3R/GT. Looking up one of the part numbers I believe it's for the Thunderbird.

I bought the kit T1171015
Although you can't order individual plates from that site, it does show the two different steel plate sizes and as you can see this is a different bike than the one you are viewing. Their schematic looks different...

Here's the manual.....

So, just be careful getting the right plate. Based on my experience and the information in the manual, there are two different sized steel plates. Eight of the larger size (smaller internal diameter) and one of the smaller size- same outer diameter, but larger inside diameter (bigger hole in middle). On my bike one of the eight larger steel plates had the groove. Unfortunately, I can't recommend the correct part number since I got the kit. I'm not sure you can get the individual parts for our bikes, but maybe a dealer can get them for you.

Thanks for replying,

I just found that Hayabusa is also selling same plates and in same thickness 2.3mm , 2.0mm and 2.6mm, i will try my luck and see if its same size, if not i will return.
