Slipper Clutch

Postby Vortex155 » Thu Apr 19, 2012 2:03 pm

Have ordered the TSS slipper clutch, anybody got experience with installing slipper clutches here.
Downloaded 2 really good youtube tutorials bout slipper clutch installation on a Honda cbr600.
Read some stuff regarding the subject...one of the things that I found out was the use or not use of the judder springs...there are some lines found of not using this into a slipper becuz this will break down to easy.
By asking I try to do as much homework before I start off with the job.

Bought the clutch holding tool and a moment wrench form 40-200Nm, the RC8 clutch needs to be torqued at 130Nm.

Hi Mate I'm going down the TSS/SIGMA/YOYO route soon, I've done alot of reading up but you mention "judder springs" whats that all about? I will probably get mine from Sigma £620 all in with the suzi k5 springs... Please tell me more!! :?:

in the LC8 they sit closed at the engine...but there are lines I've found to put them on 3th position and there's even a race team that have removed them, so this really important to have this right when you and I start off.

I paid 'bout the same for the TSS, they're both the same also.
Only the sigma was a bit more expensive here...750£/800€


btw if you search on youtube you'll find a good how to bout slipper clutch, the model is a honda 600 and its a yoyo, work is the same.

Share your experiences here,
you show yours, I'll show mines :wink:

was looking in the SD slipper clutch tutorial indeed no word on fitting the judders back in
http://www.superduke.net/forum/viewtopic.php?t=11308

but found others that mention placing it in 3th position
other that race have total destroyed their engine becuz the judder blew to pieces onbaord a 675
http://www.triumph675.net/forum/showthread.php?t=5191

If you leave them in it will effect the slipper clutch action & will ware out the small clutch plate.

STM say remove the rings in their fitting instructions.

I can see why they say that, the rings act as a mini pressure plate that seperates the clutch pack at the small plate when the clutch is engaged, if the slipper disengages the clutch pack to slip the clutch the mini pressure plate rings could effect the timing of the slip.

Mine was taken out with my slipper & have had no dramas.

and no problems finding neutral afterwards?
Maybe I also go for the no judder option.
Got to pickup my slipper this evening.

If you leave that judder plate and springs out...don't have this to be replaced with another clutch plate becuz there will be less stack height.

Think I better wait for installing before I have an answer on this, shall search for the stm manual, read what's stated there.
Meanwhile you may always set me in the right direction off course :wink:

No problem at all finding neutral, I run 10w 60 oil. Both rings removed & still have the small clutch plate in place.

Okay thx Kev for the info.

But ran into major trouble while performing the art of bolt removing. I better had stopped all efforts and went to dealers, becuz that bolt wouldn't let go and the use of a pneumatic torch wrist was required, bike is fooked now :x
broke two teeth of the outer outer clutch basket so that needs replacement also now...bugger :?

So what started as a pretty straight forward job ended with mayhem & dissaster.
Don't know that outer basket comes off so easily becuz its pressed upon the primair wheel that drives the gear train.

...think its the end of my attempts...the boy/girl who locked that bolt upon the basket in the factory sure has done a great job...that bolt will never come out I guess unless you drill it out or something :(

yeah gonna buy one myself...that damn clutch basket has to go off and that outside basket also, so engine has to be opend.
First order a new basket and find another clutch tool this one destroys the outer basket.

Okay this may seems stupid...but to release that nut is it left or right turn...i tought it was right wire, can't see any wire outside the center bolt. The technical manual don't mention it.
Thing is I have use of an electric wrench tool and it can destroy the complete gearbox when it works in the opposite direction to release that nut, so turning tighter in stead of releasing the center nut.

Image

Thought it would be more easy.
Marked that center bolt...didn't gave one mm after using the power tool...fact is the 32mm flew right over it.
Image
After measuring it seemed it's USA type so you need a 30.6mm nut to release it...this ought to be written down in the manual imo.

Anti clockwise to release, in your case put the bike into gear then undo the nut, make sure you use locktite on the nut when refitting.

I normally put the bike into gear, leave the clutch plates in place & press them down with my fingers with one hand & undo the nut with the other hand, with the plates still in place it stops the inner hub from kicking around when you use the impact gun.
