installing an ats twin carbon in an 06 350z and having issues with t/o bearing engagement. io have installed this clutch on earlier models, and had no problems at all. was wondering if anyone has one not installed and can measure the t/o bearing and sleeve height for me.
below is the measurements and pics i took of install.

this is measuring the height of the t/o bearing. it came out to 2.4"

this is all the measurements i came up with

this is the installed clutch

in all my measurements and looking at the clutch fork, the t/o bearing HAS to be .4-.5" longer for this clutch to work in this car. do i have the wrong t/o bearing and or sleeve, or is this a prob others have run into doing an install on an 06? yes, i checked the box and it is labeled for a 350z.

thanks for replies.

 

just need someone who has one uninstalled to measure the t/o bearing sleave height.

 

Anyone?

 

61 mm or 2.407 inches from the top of the bearing, to the bottom of the sleeve.

43.20 mm or 1.702 inches
is the sleeve height alone.

We just installed a triple disc on Ryan Danis's car and he does have the 06 trans. They are all the same.

looks like our measurements are the same, with respect to the TO bearing/sleeve.

Did you re-check the orientation of the clutch elements as well?

 

yup, there is basically 3 ways to install the center hub, but none of them will change the actual pressure plate height. have checked for air in the clutch line twice now. installed the motor 3 times and putting the clutch together differently every time.
putting the older stock pressure plate next to the 06 one, there is a little bit of difference in height, but hard to tell exactly unless it is installed on the motor and clamped down.
the prob i am seeing is that the measurement of the installed clutch/pressure plate does not put the clutch deep enough into the bellhousing for the t/o bearing to fully release the clutch. the clucth fork is in the middle of the window where it should be towards the front. wish i could say i am an idiot and not doing it correctly, lol, but not even the measurements are coming out correctly for it to work. if the install on an 06 had not been tried yet, i would write it off and just modify the sleeve height, but with people saying it does work for sure, and confirmation from you that we have the correct t/o bearing and sleeve, i am in abit of a spot to figure out the actual prob.
maybe a mid-year trans change? who knows.

 

grrrr....sorry that didnt help. I know it can be frustrating, but I bet it is something really simple. Please keep me posted, and let me know what you find out. I have a fresh triple in the box, if you want me to take some measurements of that.

 

is the measurement you gave me for the twin or triple disk? cause if i had a t/o bearing/sleeve designed for a triple and not the twin disk, then it would make sence and definately be the prob. a twin sleeve would have to be longer than a triple one.

 

Same bearing/sleeve for both. This particular measurement was for the triple. But the triple and twin use the exact same TO bearing and sleeve.

 

hmmm. that seems weird they use the same thickness one for both. the triple would be almost exactly the .4-.5" difference in thickness that is needed. i know the tilton triple uses no spacer on the t/o bearing, where the twin disk uses a spacer to make up the difference to get the correct engagement height.

 

The physical outside dimensions of the clutch are the same. The triple uses a thinner top pressure plate, that compensates for the extra disc. and metal plate. But the total outside thickness of the clutch/flwyheel assemble is identical between the twin and triple, so the TO bearings are also identical.

Scott, i got you message, but i am swamped today..i will call you after 6pm my time.

 

was out of range when ya called today. will give ya a ring first thing in the morn here before i get out of range again. thanks

 

I wish we were in the same time zone..keep missing each other.

Did you mic up that top plate we talked about over the phone? Email me the measurements when you do. THANKS!

 

was working to late tonight to make it back to the shop.

 

any update to this saga?

 

OZ and I checked all the measurements, and the clutch in his hands, is identical to a new one I pulled out of the box. I think he is still investigating some other possibilities.

 

Thanks

 

from what ats is saying, it is an oddity. i am pulling my motor right now (an 03) and will be checking everything against that. kind of my last option right now as most all of the measurements match up to a brand new ats twin but wasn't able to check a couple other vital specs to clutch depth. i know manufacturers like to change and test stuff before full production, and we may have one of those. ats says the clutch has not been approved for 07 models though with the hr motor. i hear because they have not tested it yet though, and not sure if it fits or not.

 

any updates on this issue?

 

nothing yet, was out of town for a few days. might be able to get mine pulled tonight and find something out. those with an 06 should not hold off buying a clutch though. it sounds as this is an oddity and easy to fix with a little machining work. just wanting to find out what portion is warranting the need to do modifications first before making something.
