New clutch issues

Jinxx

Ok Im having a issue and not sure of the direction to take ....so I have Z1 road race clutch in my turbo z and from the first day I noticed a strange smell after driving in ..thought it would break in and go away which ..It did get less and less and I didn’t hink much about it now I’m about 7k miles on it it drives fine but I have noticed it is difficult to go in gear while idling....I have checked everything on the hydraulic side and it seems fine ...now on my other z I had the same clutch kit installed and had no issues with it ..no smell after install and no issues going into gear while idling....so I wondering if maybe the first kit may have been defective or if there was a installation error ...one thing that I noticed from the install is that on the first one after my installer was done was that the clutch grabbed instantly when the pedal came off the floor and my installer adjusted the pedal out to max adjustment to get it normal....with my second car no adjustment was needed after install

.....so now I’m trying to decide should I replace the pressure plate and disc with another Z1 kit ...should I go with zspeeds stage 3 pressure plate and if I go that route will the Z1 flywheel match up to it ....or is this a issue of installation and it’s some kind of adjustment inside that needs to be corrected...

Any info would be helpful

Really does sound like hydraulics. I know you said you checked. But I'd check again.

Completely flushed out fluid replaced ....no leaks and pedal is firm all the way up and down

Sounds like the clutch isn't fully disengaging. Are you able to adjust the rod on the pedal such that it's not screwed in (into the clevis) as much? You'll also need to readjust the limit switches on the top/bottom.

I would get this resolved asap because you're causing damage to the trans when going into gear if the clutch isn't fully disengaged.

Yes I feel like it isn’t disengaging fully ..Pedal has been adjusted ....and is adjusted for full stroke on the master cylinder.....that was my first thing I started looking at...and yes looking to to resolve is ASAP ....just started feeling it and i never force it into gear and there isn’t any grinding whatsoever

Is it difficult getting into 1st only or all gears? If 1st only, what happens if you go into say 4th, then immediately into 1st?

If it's all gears, then possible clutch spacing isn't right inside the bell housing¿? Slave has a finite amount of movement to disengage the clutch. If spacing isn't right then it doesn't disengage all the way.

Was it fine after initial install and this issue just developed?

Are all the hydraulics stock? Pedal, CMC, CSC? Or are any parts aftermarket?

So update on clutch ....I replaced the Z1 road race clutch with zspeed stage 3 clutch kit checked everything out while it was apart ...hard to really tell but noticed the center of the disc looked like it turned blue from heat ..my installer said it was prolly dragging. ..also one thing I noticed from first install was vibration in the clutch pedal as I would release the clutch while driving which he said sounds like some warpage in the plate or disc but I can’t say for sure .....however after the zspeed clutch install everything is very smooth no vibration and the issue of not going into gears is gone ...pedal is much easier than Z1 clutch everything feels very good now and I am about 400miles on it.

Was the master cylinder replaced with the rest of the hydraulic system? If not, you may need a new master.

No master cylinder wasn’t replaced due to the fact the car was new with only 2k miles on it ....and after the zspeed clutch was installed everything was fine with the master cylinder ..only thing changed was the Z1 kit to the zspeed kit and all issues are gone

It sounds like you didn't have enough clutch to start with. If the disk turned blue, it got real hot. If it warped, it was after it got so hot. That stinky smell is not what you want to smell after a clutch install. The clutch smell was from the excessive heat.

Jinxx

The clutch had vibration in the pedal and the smell lasted quite awhile even from day one so there wasn’t anything to cause excessive heat ...clutch was broke in 2400 miles before car was taken to the Dyno

A clutch should never stink (smell). Vibration in the pedal is normal. You should have took it back to the installer to check his work. I can't believe you drove it 2400 miles to break it in. Crazy

Jinxx

I thought the vibration was normal and due to the lighter flywheel at first as well ..After zspeed clutch installed no vibration there..and also had same Z1 clutch kit installed into my supercharged z as well..same installer no vibration no smell no issues ..the 2400 miles wasn’t necessary breakin miles ...just how many miles that was driven before getting it to the Dyno ...the car wasn’t a daily driven car and the issue wasn’t as apparent ...more of a random issue ...but more noticed when I started driving it daily and comparing to the clutch in the supercharged car.

I’m not saying that Z1 clutches are bad or bashing them in anyway but I do believe that particular clutch kit was defective ....can it be proven prolly not but I’m not trying to return it ..just giving info on what I delt with ...and if I had to do it over again ...I would bypass the Z1 clutch kit and go for the zspeed kit ...lighter pedal and much smoother engagement than Z1kit
