New twin plate clutch install - wont disengage
« on: February 13, 2018, 05:02:50 PM »
Hi
Replaced worn out clutch in weekend with a very expensive nismo copper mix twin plate and flywheel.
Thought all had gone well untill tried to drive away and can not engage any gears with foot fully down on clutch pedal.
Thought slave was bad so have replaced and bled and still problem remains. Has anyone else experienced this with twin plate clutches before?
Me and mate installed and went by instructions it was pretty straight foward. We are pretty good with that stuff we thought.
Do they need a longer rod or something on slave to push further or s there something wrong with the imstall?
Many thanks

Don't know really but did you use a stock release bearing or did one some with the clutch? Pull the rubber boot off and see if you can tell if the release bearing is seated properly.

used the one that came in not. looks like it's where it should be. I can feel slight free play if i pull fork back and can feel it hit the clutch teeth just after. it should work. but doesn't

Just pulled off rubber to see whats going on in there and it all looks the way it should be. Cant push the fork by hand as its very hard. Might leave rubbe roff and put slave back on and get a mate to pump the pedal while im under there looking at the thrust bearing.

Looks like everything is doing what it should be except no disengage. Looks like will have to pull apart again fml

when i was putting my triple plate in, i found i needed a shorter release bearing carrier to get the clutch disengaging correctly.

I only found this after doing some deep googling.

from my build thread:
"Note for anyone running a Exedy triple plate clutch (ie NM033SR) you will need to change your clutch release bearing carrier to a shorter one that puts the bearing closer to the clutch fork, part number 30501-02C74"
god is just an imaginery friend for grown ups
