Jersey Posted April 28, 2005 Share Posted April 28, 2005 While installing my new ACT organic clutch disk last night, i noticed it had "EXEDY" engraved on it. Just a heads up. Quote Link to comment Share on other sites More sharing options...
sims76 Posted April 28, 2005 Share Posted April 28, 2005 I just got the same clutch in the mail today...I'll check mine when I get home. Quote Link to comment Share on other sites More sharing options...
Jersey Posted April 28, 2005 Author Share Posted April 28, 2005 I'm not sure if ACT just started using EXEDY plates but, i also noticed that my 2 year old ACT plate looked different then the one i just bought. On the new one, the spacing between the organic pads are further apart and it had 4 springs that are bigger and thicker then the old disk which had 6 lighter weight springs.

sims76 Posted April 28, 2005 Share Posted April 28, 2005 I got the NX2-HDSS kit....no reference to Exedy anywhere on it. The PP is samped with "Made in the USA" and it does have four thick springs on the disc as you described. How much more pedal feel will I have with this thing? Currently my clutch pedal feels almost too light, I almost want it to be stiffer. Quote Link to comment Share on other sites More sharing options...
BayAreaZT Posted April 28, 2005 Share Posted April 28, 2005 The ACT clutch I put in my old Z said Exedy. That was back in 2003. Quote Link to comment Share on other sites More sharing options...
Jersey Posted April 29, 2005 Author Share Posted April 29, 2005 I looked for NX2-HDSS here - CLICK but couldn't find the info on that kit. 2 years back, i bought the NX2-HDMSS kit which had the four smaller spings and it didn't say Exedy on the disk. This time, i just bought the disk (ND007S), TO bearing and pilot seperately and the disk was stamped Exedy. It was a major pedal increase from the stock setup. As a matter of fact, see below what happened. Check the arm your using for stress cracks before using it with the upgraded PP. May save you a headache of having to pull the trans sooner than you want GL. Quote Link to comment Share on other sites More sharing options...
sims76 Posted April 29, 2005 Share Posted April 29, 2005 Thanks Jersey, I will definitely check the fork for stress cracks. I'm tired now, just got done taking the rear out (swapping my 3.54 back in place of the 3.9) and dropped the tranny (and about a quart of fluid all over the floor.) Good to hear that the pedal increase is significant. Here's the link to a site that lists my part # with description... http://www.nipponpower.com/drivetrain/clutch/act_nissan_260z.html Although, I ordered from Courtesy Nissan... http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=NX2-HDSS&Category_Code= Quote Link to comment Share on other sites More sharing options...
Jersey Posted April 29, 2005 Author Share Posted April 29, 2005 Got it sims. Thats the same kit i ordered a couple years back, just a different # i guess. I just got my trans back in last night, finishing at 3am. All worth it after being on the jackstands for about 3 weeks! Good luck with the install and let me know how you make out. BTW - i swapped the slave to a 11/16" to get more throw when i did the original ACT install, which again, increased pedal pressure more. With the stock 3/4" SC and with the pedal stop adjusted up all the way in and, all pedal freeplay taken out, the pedal needed to be on the floor to disegage. The smaller 11/16" SC helped but i think a better option would have been to go with a larger MC, like the 3/4" Tilton. Just a heads up. Hope it all works out perfect for ya.

Hope it all works out perfect for ya. Everything is not perfect, the ACT will not disengage. I've bleed the crap out of it and adjusted the MC rod and still no luck. I had a friend push in the clutch pedal fully while I jammed a bolt in between the fork and the bell housing so that the fork couldn't return to resting position. Now on the second pump of the pedal, the cluch disengages. I marked this spot. It only needs about another 3/16" of movement to disengage fully. This only works because I don't have a boot on the clutch fork right now. I did order a Tilton 7/8" MC from Summitracing.com. Part # TIL-74-875U for $67. Looks like the 11/16" 1988 Nissan Pathfinder slave cylinders can be had for less than $20. I'll be investing in one of those too. Thanks for this info Jersey, I would be on the verge of tears right now without it. (This is the second time in 3 days that I've pulled the flywheel, clutch, PP, and trans.) Will this combo get me the extra 3/16" of SC travel that I need???? Quote Link to comment Share on other sites More sharing options...
Ivan280zt Posted May 12, 2005 Share Posted May 12, 2005 Hey guys what is torque rating on those ACT clutches and what are they going for. I am going to buy new clutch in day or two and i am looking at SPEC stage 4 or 5 right now but i would like to get some feedback on other clutches like ACT (sorry for going of subject guys).

sims76 Posted May 12, 2005 Share Posted May 12, 2005 Ivan, See my links above for both the ft/lbs and $$$. My kit (street disc - Non puck type) was about $350 and is rated for 400ft/lbs. Quote Link to comment Share on other sites More sharing options...
Jersey Posted May 12, 2005 Author Share Posted May 12, 2005 In my opinion, that's exactly the right direction to go in, with the 7/8" Tilton. Joe (Rags) mentioned to me over a year ago that he used this same tilton MC on one of his Z's and it works great, and of course i nevr bougt one. Just one of those "never get around to it" kida thing i guess. Let me know how it works but i bet it'll solve your problem. The pedal pressure may increase a little more, but as long as disengages, right? I'm using the 11/16" slave now and had raise the pedal height, adjust the clutch rod out to where there's basically no free-play, and it still takes a little more then half the pedal to fully disengage! I would just try the stock 3/4" slave with the 7/8" MC. And then if you needed a little more, you could always bump the slave down to 11/16" but i'm betting you wont have to. If you running the T5, the pathy slave will bolt right up. For the Nissan tranny, you'll have to space the pathy slave out a little to have it sit flat. I think fl327 found an 11/16" SC that doesn't need to be spaced for the nissan trans but i cant remember what car it was from. I'll see if i wrote it down at work tomorrow. Keep me posted on the Tilton if you would. Good Luck. Quote Link to comment Share on other sites More sharing options...
BayAreaZT Posted May 12, 2005 Share Posted May 12, 2005 If you take off the rubber stop for the clutch pedal, you may be able to get that extra 3/16" to disengage. This is what I had to do with the stock MC and slave. No clutch freeplay either. Quote Link to comment Share on other sites More sharing options...
260DET Posted May 13, 2005 Share Posted May 13, 2005 When as a precaution a new Exedy clutch plate was fitted to mine, it wouldn't disengage. Even though nothing else was changed including the pressure plate. Had to go to a smaller diameter slave cylinder. The facing on the Exedy plate was quite rough in texture so my theory is it was this that extended the disengagement process, so requiring more travel. Nice smooth but firm clutch action though.

sims76 Posted May 13, 2005 Share Posted May 13, 2005 The 11/16" 1988 Nissan Pathfinder slave was the first to get here in the mail today from http://www.rockauto.com It was $18 shipped. I installed it, bled it, and viola.... clutch disengages/engages about 2-3" from the floor. I'm having trouble imagining if this is a comfortable spot or not because my old clutch had a much more "linear" feel. This clutch clearly has a point of high resistance and then when you pass that, the pedal pressure decreases. I'm going to take the night off from working (still have to put the driveshaft & exhast back on) and drive it tomorrow. If all is well I'll likely return the 7/8" Tilton MC that I ordered. THANKS for the assistance guys. DYNO results coming as soon as it's broken in!!!! Quote Link to comment Share on other sites More sharing options...
Guest Loose_Screws Posted May 13, 2005 Share Posted May 13, 2005 I'm having trouble imagining if this is a comfortable spot or not because my old clutch had a much more "linear" feel. This clutch clearly has a point of high resistance and then when you pass that, the pedal pressure decreases. Newer style clutches (at least for heavy duty trucks) with higher clamp force have 'break-over', very similar to the feel of a compound bow. I prefer the linear feel myself, but get in traffic with stop/go and you will appreciate the lack of pressure needed to have clutch disengaged!

sims76 Posted May 13, 2005 Share Posted May 13, 2005 Thanks Loose Screws. Yes, the compound bow analogy is a very good way to describe it. Your video is great. I have been playing it a few times a week because I'm having "track envy." (I haven't made it to the strip or dyno yet with the new setup.)

Jersey Posted May 15, 2005 Author Share Posted May 15, 2005 Congrats Sims. Glad it's working for ya. 2-3" from the floor is a pretty far leg throw, no? I think i'm going to get the 7/8" Tilton to make it a quicker release and, i'm having another issue with the stock/newer MC now... with the increased pedal pressure of the ACT PP, when i'm holding the pedal down for a little bit, i think the fluid is passing by the MC plunger and the slave starts releasing slowly which starts engaging the clutch by itself. I dont think my stock MC is stong enough to hold the ACT PP's pressure. Hopefully the Tilton has a stronger seal. You may want to try that before you return the Tilton. Clutch in until it disengages, put it in gear and just hold the pedal steady for a little bit to see if the MC can hold the pressure. And what video??? Pass it on Loose!
