Broken Detent Spring

[warp9.9]

could you post a picture of the thrust washer? The reason is because I do not know of a thrust washer in that area. The older style pressure plate and needle thrust bearing used one but not the newer. Triumph has incorporsted a shim washer to remove some slopp/clearance in the 2011 touring but it also uses up a lot of the allowable wear tolerance on the fibers. mine only has the wavy washer which I think is just there to keep the lifter piece from bottoming out it the input shaft bloking oil flow.

below is the old style lifter piece 04-early 05



Below is the old style pressure plate and thrust bearing I was speaking of



from the looks of your new lifter piece thay have made a change in the lower shoulder length which will remove soem of the clearance between the back shoulder and the input shaft. can you also post the part number in case it has changed?

Make sure you monitor your free play while the clutch beds in. To tight is not good.

Warp, the shoulder section you are talking about is the extra dimension that replaces the thrust washer. I don't have a needle bearing but a ball bearing which has a slip fit over the lifter piece(so it can slide in and out of the input shaft. The part # of the new lifter piece is-T1170203. The photo is the thrust washer and original lifter piece.

Ok that is the so called shim they added which I do not use in mine. They did not have them in 06 and it worked great so I figure why screw with it. plus is takes up wear room on the fibers which allow the bearing to lifterpiece to bottom out early.
your lifter piece bearing looks like below



and the pressure plate is like below

This is some interesting stuff here. At least it appears that Triumph is working on the problem. And what is this "judder spring" thing. I know my 06 hardly "had" a spring plate thing in the original clutch pack, that would eventually come apart and trash the clutch. I installed an Energy One Kevlar clutch pack, and by leaving out the "spring plate" allows an extra friction and steel plate.

IMO the anti judder spring and seat helps soften the take up on the clutch an drive line. I eliminated mine when I went to the MTC fibers and Billet forged clutch basket. I must say I wish they would publish changes so it would be easier to help people on these sites. I sucks retracting what you said because they might have made changes you do not worry about. This last change which looks like it removes some of the slop or clearance between the back of the lifter piece and the input shaft which at the face value looks great but still might eliminate some of the wear allowance on the fibers.

HD Clutch??

While we are in the clutch area, if someone replaced all of the friction plates with the 60 friction pads each (the last friction plate nearest the pressure plate) in place of the 8 in the middle of the pack(50 friction pads each)...would this constitute some type of high performance clutch?

I doublt it unless you end up with more surface area of pad.
Below is the OEM fiber (right) verses the MTC (left) fiber. I believe pad and spring pressure is what does the gripping. every clutch needs to slip a little when racing or the tire needs to spin otherwise if there is now slippage anywhere something will suffer from catastrophic failure.

Warp, I was just curious, also the friction plate on the right I believe has 50 pads and the outer friction plate against the pressure plate has 60 friction pads The 60 pad would come a little closer in area to the MTC pads...Just curious is all on how it might perform.

 

[idk]

I have been using the MTC pads for a few years and much prefer them to OEM. They don't use the judder spring, but you do get more leeway in clutch adjustment.

It has come to my attention that some people think the large washer below is a thrust washer.



below is the proper placement of said washer/spacer









It is in fact a spacer that goes between the internal clutch hub and the boottom inside of the clutch basket. IT IS A MUST!!!!

Now I was on Bike bandit because when I bought a complete clutch assembly from a 2011 R3T I noticed a extra washer/spacer in the assembly. shown below







Now on Bike bandit it shows this shim in the 2011 Touring but not on the Roadster Why I am not sure but it looks like the changes in the new lifter piece posted above would in fact be a thickness change to eliminate having to put this washer on the lifter piece. I wish I could verify this but Triumph never gives reasons for changes so this is my best guess.



The real question is does someone have the new shoulder measerment so I can compare it to the shim thickness?
