Hi all not sure if this is the right category for this post but I thought this might be useful to someone out there.

While I was inspecting the Torque Converter I thought I'd check the clutch basket. I have the actual Triumph Storm manual but i mainly use the online free one because much of it is the same. To my knowledge the clutch mechanisms are the same from the 2010 models through to the end of the line. But no, that isn't the case.

Anyways, I opened up the online free manual and it said the fiction plates have a service limit of 3.5mm and a standard of 3.72-3.88mm. So when i checked my friction plates I found that they were all less than 3.5, ranging from 3.3-3.5. So I thought- crap i need to order a new set. So i got my new set via Fowlers express delivery then got them, inspected the brand new ones and found that they were 3.5mm new! And thus by the online manual, out of spec.

So I whipped out my Storm manual and it says that the Service limit is 3.2mm and the Standard is 3.3mm-3.5mm. What is interesting is that it doesn't specify that this bit is for the "Storm". The manual I have covers: Thunderbird, Storm, Commander and LT versions but doesn't say that these specifications are not for the Thunderbird.

I was annoyed with myself for not checking this because i just wasted money on a new clutch fiction plate kit, that yes i will use one day.

I then also noticed extra instructions to check the Clutch Pack Height if you are installing a new pack that should be 37.6mm with a tolerance of +0.38 -0.62mm. These bit of the instructions are not in the original manual online.

When I get around to it i'll add this all to my website, but for now I'm posting it here just in case anyone else checks there and wonder why the numbers don't seem right.

Hope that helps someone.

Yes I noted this back in May 2017:- "Having just installed new plates I discovered all the new friction plates are significantly thinner than the service limit specified in the workshop manual, so it looks like the manual is wrong, so a dealer measuring your plates would think they're worn - even though they are not."

Happened to have my clutch apart recently and checked a few of the friction plates. 3.8 mm thick. 2010 1600.

Seems to be some misinformation about or Triumph has changed specifications since the 1600. Pete , so you didn't change the plates when you did your 1700 kit? Seems your clutch will go a long way

Don't know but mine are within the original specs. No change for the BB other than the springs which were apparently 1700 ones.
