Ok I think I see how this slipper clutch is supposed to work now. As I was looking at it and the pictures I forgot that when I put the clutch on the bike I will have installed the original clutch springs which w/o plates will be pushing the pressure plate away just based on spring height once the plates are installed then it will be the stacked height pushing also against the springs.


I'm ready to tackle this when the gasket comes in next week!!!!!

My YOYODYNE slipper worked perfectly at our last track day and no exploding disks!

One thing that I forgot to mention on the install was the fact that you WILL need to adjust your slack in the clutch cable.

No exploding disks but I did manage to blow up a bolt or two. :shock:

I finally got my clutch gasket from Triumph this weekend and began installation last night. The installation was almost complete when the fourth of the five spring bolts snapped while I was tightening the pressure plate. I had the torque wrench set to 10nm, which was what the stock bolts were torqued to. Seeing how much thinner the Yoyo bolts were than the stock ones I should have made an adjustment but he first 3 seamingly went fine. Upon removal of the pressure plate to reinstall the stock clutch, a second bolt snapped. I guess in using the stock setting I over-torqued the bolts them causing them to snap. :evil:

Just glad I didn't screw up the threads in the drum. So now I'm trying to get replacements for the bolts and collars.

Blacktriple did you manually tighten the pressure plate bolts?

I used a small torque wrench for my bicycle that went to 7NM and then just tightened a little more with a 1/4 inch drive ratchet. the bolts didn't break. If I had a torque wrench that went to 10Nm I would have done so per the Triumph manual. I thought briefly that the bolts looked smaller. Where are you getting the bolts ? from Yoyodyne? Its not a big deal to change them out... What do you guys think? Should I change mine?

 

[brettmess]

KevinH your technique sounds fine to me, no need to replace.

I went through the CD that came with the clutch . I didn't find a reference to the triumph 675 but I did find instructions for other bikes that used the YOYODyne slipper cluch basket and each one said to torque the bolts to 8 to 10 NM. So I think I'm ok also. Going to get another torque wrench .., I think Park sells one. Every bolt on these new bikes is a small as possible to save weight and the torque settings are fron 10 to 20 NM. I hate stripped threads ... bolts... I was at a track day at Roebling Road Two weeks ago ... Young man dropped his drain plug because it was n't tight enough... oiled half the track .. went past 4 black flags... we wasted 1 1/2 hours for clean up. 2nd time I have seen that .

 

[brettmess]

Thats why everyone should use a good torque wrench and at the least if your going to be on the track safety wire your drain plug.

damn that was a very helpfull post

This is a late post . after i installed the slipper clutch I had an issue that I felt a click in the lever when I pulled the clutch in and downshifted. I also heard it. This is normal. I have talked to my mechanic about it + I emailed Yoyodyne and their response was

"What happens is that when the clutch lever is in, there is little pressure on the slipper clutch ramp parts.

When you downshift, the transmission tries to speed up the engine. The slipper clutch than goes into slip mode, and the hub “slaps” the pressure plate. This slapping is the click that you feel in the lever"

At times its not there at times you can really feel it . so if you pull the clutch in and downshift at the same time its simultaneous

I had a few people PM me about the HOW TO install and I now reposted for all to use.

Does anyone who fitted the sigma slipper happen to know if the clutch plates are rearranged in the same manner? I heard that the judder springs should be removed?

While your in there I would remove them. I have an extra plate, the next time Im in there I will replace them.

Three track days and no problems with the judder springs. So I think they will be fine for street and track day use. Racing??

If your going to run the judder springs defenitely put them in the third or higher position as they will fall behind the ramp if you do not, regardless of the brand.

BlackTriple,

Would you please re-post the "How To"...I am extremely interested in the install, and will be helping ofcounsel do his. Thanks! :twisted:

BTW, why did you remove the information? Just out of curiosity... :?:

 

[Sponge Bob]

i´d been interested in the weight of those parts



did anybody compare stock clutch with yoyo, sigma or tts?


heard they´d be heavier than stock :?



cheers

Well seeing that you asked, I am a little butt hurt that it was never stickied seeing that I spent a ton of time creating this for others and saving them a ton of money being able to install the part on their own. I mean give me a break theres a how to install sliders,windscreen??? and levers etc..All good write ups but if you cant figure those out on your own you should not be wrenching on your own bike.

This has to be the most technical HOW TOO.. on this board!

Seeing that you asked that is my reason for removing it :wink:

The yoyo clutch is actually a little bit lighter than stock.

Well, I apologize for that. Typically, people ask for certain threads to be stickied....at which point we make a decision to sticky them or not. Before this point, I hadn't really looked at this thread since I didn't have any particular interest in a slipper clutch. Once again, I am sorry you were "butt hurt"...and I would be glad to sticky this thread for you. :lol:
