big-phil Posted December 22, 2007 Share Posted December 22, 2007 I am starting to hate my ACT unsprung 6 puck clutch, so I bought a new ACT sprung 6 puck clutch disk!! Put the car on the lift, took the tranny out, went to put the new clutch disk in........wrong one! I ordered the turbo one which is the bigger one. I forgot I have the smaller flywheel:( Talk about depressing. I had to put it all together like it was arrrrrrrrr! New disk $160, to change for the bigger flywheel $550+ I'm going to send it back and order the right disk, I'm so bummed. Quote Link to comment Share on other sites More sharing options...
Forrest Posted December 22, 2007 Share Posted December 22, 2007 550$? for what? Fidanza 240mm flywheel is 285$ http://cgi.ebay.com/ebaymotors/Fidanza-flywheel-Nissan-240Z-260Z-280Z-280ZX-Pickup_W0QQcmdZViewItemQQcategoryZ33732QQihZ004QQitemZ140190516055QQrdZ1QQsspagenameZWDVW (That's a great deal, normal street price was about 350$ until a couple of ebay guys started selling for cheap.) The only other part you need is a 12$ throw out bearing collar from Courtesy Nissan.... Go for it man, you won't regret it! I'm actually in the process of putting a new friction plate on my extra Fidanza and putting it on my 76 this morning. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted December 22, 2007 Share Posted December 22, 2007 Yeah I ordered a Fidanza Flywheel and it's sitting right next to my Sprung ACT six puck disc. I am waiting for the snow to thaw so I can perform the installation. I know the frustration though. What a PITA. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted December 22, 2007 Share Posted December 22, 2007 i hate my ACT full faced sprung clutch disc. I have not been able to have it fully disengage for 1st/reverse ... even with a new master cylinder (3/4") and a 11/16" slave from a pathfinder. hate it Quote Link to comment Share on other sites More sharing options...
big-phil Posted December 22, 2007 Author Share Posted December 22, 2007 $550 for the ACT pressure plate and clutch disk. If I get the flywheel, I have to get another pressure plate also. Quote Link to comment Share on other sites More sharing options...
Chemicalblue Posted December 22, 2007 Share Posted December 22, 2007 You should ask Brice about clutch masters brand, I think its cheaper and will hold more hp. Thats what I'm running and it feels stock other than the pedal being a little more stiff. Quote Link to comment Share on other sites More sharing options...

That's not the fault of the clutch disc. Quote Link to comment Share on other sites More sharing options...

I think my whole kit was only 315$ from nipponpower. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted December 23, 2007 Share Posted December 23, 2007 i tried both collars.. i cant remember the sizes.. but its properly sized. Its primarily the pressure plate =( Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted December 23, 2007 Share Posted December 23, 2007 i hate my ACT full faced sprung clutch disc. I have not been able to have it fully disengage for 1st/reverse ... even with a new master cylinder (3/4") and a 11/16" slave from a pathfinder. hate it I bet that makes for one very stiff clutch pedal... I am running a 6 puck spring hub with a Fidanza flywheel and a heavy duty pressure plate. I had the same problem as you discribed and I followed a similar route, my pedal was so stiff I actualy bent the pedal. After talking with an engineer at Willwood I bought one of their 3/4" clutch masters and a 3/4" stock Nissan slave put it all together and bled it, now it works perfect and does not feel like a full blown workout to drive.

randy 77zt Posted December 23, 2007 Share Posted December 23, 2007 i run a act 240mm full face disk and cover-i like it .clutch is okay to drive in bad places-like downtown sanfrancisco.i dont like the puck clutches engage -and damage the flywheel after they wear out.supposed to be good for 400hp-good enough for my turbo l28.

Dragonfly Posted December 23, 2007 Share Posted December 23, 2007 big-phil sorry about hyjacking your post. PrOxLaMuS© I just thought of something else. One of the problems I had with the disimalar sizes between the master and the slave cylinders was that when I would push the clutch pedal all the way to the floor (first and reverse) I was actualy over extending the throwout bearing into the pressure plate fingers and causing binding in the clutch assembly. With you having very similar problems to what I had I would suggest that you pull yours and take a look to make sure there has not been any binding.

proxlamus© Posted December 23, 2007 Share Posted December 23, 2007 thank you for your suggestions Dragon! you may be right. I will check it out.. I do know that in 1st/reverse.. i can tell the clutch is not fully disengaged.. one example is sitting at a stop light with the clutch it.. i can feel the clutch chatter slightly.. and when i had bad u-joints in the half shafts they were clanking around. So its not fully disengaged. Maybe ill try going back to the stock slave cylinder.. instead of the Pathfinder (11/16" one). Is the stock Z slave a 3/4"?

proxlamus© Posted December 24, 2007 Share Posted December 24, 2007 I am ruling out.. im definitly not over extending.. i tried all clutch positions im not moving far enough Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted December 24, 2007 Share Posted December 24, 2007 Is the stock Z slave a 3/4"? Yes it is. I am ruling out.. im definitly not over extending.. i tried all clutch positions im not moving far enough Here is something else for you to try. Get under your car where you can see and reach the clutch slave. Pull the slave off then push the rod into the slave with you finger. If the rod is rock solid and will not push in your master is bad and needs to be replaced or you need to do some major adjusting of the clutch pedal inside the car (the adjusting rod for the pedal is pushing to deep into the master). If the rod pushes in with a slightly stiff but smooth travel all the way then your hydraulic system is fine and you need to check all your mechanical parts, the first being that the clutch fork with the slave installed is at a 90* angle (or slightly closer, acute angle) to the rod in the slave. If it is keep looking deeper, if it is greater than 90* then you need to check the collar that the throwout bearing sits on and check that the fork is not bent.

naviathan Posted December 24, 2007 Share Posted December 24, 2007 (the adjusting rod for the pedal is pushing to deep into the master) Dragonfly I have found this to be an issue with some replacement master cylinders from Advance and Auto Zone. My clutch pedal in my 81 sits very high because I had to adjust it all the way up to get the rod to completely disengage the master cylinder. I was thinking about cutting the rod down, but then I worry I won't have enough movement to completely disengage the clutch. I like the Wilwood setups and especially Dragonfly's setup, but I don't know if I want to take the chance on buying the wrong parts and not having everything fit like it should or work properly for that matter being I'm using the stock tranny and hydrolics.
