Hello all...

Just lookin to fit these Barnett 'heavy duty' plates and noticed that 2 of the 7 rings have a different ring width???? Not like the stock plates which are all identical...Any rhyme or reason behind this?

RedBird

????? My service manual says that the innermost and outermost friction plates and outermost steel plate are different from the other plates--this is talking about the STOCK plates. I assumed the difference was thickness--I didn't use the Barnett plates because the stronger Barnett springs solved my problem.

Hope this helps,

Likewise on the springs...i dont actually have a problem with the clutch...but had bought the plates prior to getting better advice...I've got to get to the crankcase breather so thought while i had the clutch out i might give them a try....

Just want to correct my earlier post...while all the stock plates on my 06/07 T100 are dimensionally identical the inner and outer most plates have larger pads than the other five plates giving a greater overall pad surface.The corresponding barnett plates have a larger inner diameter and thereby a smaller overall pad surface than the remaining 5.????

Don't know why this is?

Have fitted them and they seem to work great so don't suppose it really matters but it would be nice to understand the logic?!

Ps Another Observation....The Barnett Clutch assembly is thinner overall compared with the stock plates ...as a result, the adjuster is much further down its range than with the stock setup.

Anyone for cake??

I would never try opening up the engine like that outside in my neck of the woods...the wind blows nearly all the time here with lots of dust, etc.

I believe the HONDA part number was still on my package of Barnett clutch plates when I received them.

You're probably very wise...but i had little choice and it was calm and dry. Likewise on the Honda pn no's but that doesn't explain the mechanical differences in their designs???Or is it just a case of these fit so that'll do...knock em out to the punters!!?? Like i said though they do seem to work fine...

As another aside my bike appeared to have another anomaly...reading the haynes manual it describes the removal and replacement of the breather rotor and its respective plate...Well i have the plate but no rotor???What do you think about that?

RedBird

I see no mention in the Triumph service manual of a rotor involved with the breather. The seal is in the cover, and the centrifugal breather attaches to the starter gear that is in front of the clutch assy. It definitely rotates as it is bolted to the gear. The centrifugal breather fits into the seal in the cover when the cover is installed. I didn't bother with disassembly of this when I replaced my clutch springs since I was having no problems with the crankcase breather and everything looked good to me.

The mystery is solved...Apparently there was a design change post 05 to address some minor concerns(I suspect the changes were as much economical as mechanical) the seal and 'centrifugal' breather 'rotor' no longer appear on the newer engines.The breather issue i was refering to was the case spiggot which links to the air box )on later bikes it appears from the inside face of the breather hump on the left hand side of the engine cases). I had managed to dislodge this and it had dropped inside the breather cavity ...to access it you need to strip out the clutch entirely which also requires the removal of the starter gear. All because the spiggot is just a push fit from inside to out..not a great design feature but no biggie either !i've bonded it in place now so it should be good going forward.

never sussed out the differences in the clutch plates though...
