Clutch problems

Ron

Alright guys, so I recently bought a Southbend TZR clutch and flywheel with ZSpeed's CSC. I have 2 problems.

After the clutch was installed it felt good. Engagement was at the top (like stock) and I had about 1'' or less of pedal play. After I took it out for a drive everything seemed ok pedal wise. After about 5-6 miles of driving, pedal play increased to almost half of the total pedal swing (60% play 40% engagement) and engagement point was no longer at the top.

Since then I have tried adjusting the pedal inside the cabin, gravity bleeding for about 20min, then regular bleeding for about 30min pumping about 20 times between valve openings. After I am done pedal feels ok but the same thing happens after I drive it for a a few minutes.


The other problem I have is that regardless of the pedal feel, it is hard getting into any gear after putting the car in neutral. This only happens with the engine on...
I start the car in the morning, force it into 1st and drive around, all gears engage ok. I get to a red light, put in neutral, release clutch... when I try to go into 1st it doesn't want to go, I have to force it in again. It does the same thing with any gear I try from neutral. Once I push hard on it and get it into gear, I can row through all gears again with no problem..

I think issue number 1 is air in the system but I don't know how that could be since I've bled the sh1t out of it. Issue number 2 sounds like the clutch is sticking or CSC is not pushing all the way in.

Advise?

You're having issues like me? I thought SB already remedy this issue by now.

I had my clutch pedal readjusted near the top as well, and it's still sticky getting in and out of 1st and 2nd gear on cold starts. I have to put it in 3rd the back to 1st to get in. While stuck, the car still crawls.

Weather hasn't been so great, so I've not had a chance to test the 1-2 shift at high RPM. Always get locked out and grind.

maybe air bound?

Read the post I just posted, There is air getting trapped up by the master. Fix this and all these issues will go away for you and Ron and I have a feeling all the others that have had this issue, I have already talked to Ron and he is going to do what I have found and get back with me, I Installed his exact set-up with all new parts just like his in our 370Z today. It works perfect with no issues, Just have to get the air out and adjusted correctly. There are plenty of these out in use working perfectly and some that do not, The ones that don't are either not adjusted right or have air in the system still.


This> South Bend Clutch-bad install

Let me know if that works Ron, about to do my install w/ new CSC etc.. sounds like Joe found the problem with bleeding the system when installing a new CSC. Good stuff!! Johnny was telling me they spent forever bleeding your car. That explains it.

Status update. All the fvcking air is out!!! Drove 30+miles. Pedal remained the same. My god does this thing shift fast.

Here's what I did:

-Drain the system to the last drop.
-Gravity bleed until you go through about 5-7 reservoirs (don't let it go below "min"!)
-Close the bleed valve from the CSC, pump pedal about 30times. Hold pedal in. Open valve. Repeat this about 10 times.
-Adjut pin on the pedal to where it is about flush with the clevis or about 1 thread inside.
-With pedal all the way out and no pressure whatsoever on it, crack the slave valve open and close it quickly. Do the same with the master.
-Pump a couple of times.
-Go drive and enjoy the clutch!


Bad news... Issue number 2 remains. I am still having the problem getting into gear after putting the car in neutral and releasing the clutch. When I force 1st the car moves a couple of inches forward, like the clutch is not disengaging completely. Once I get a gear in and get the car moving there is no problem shifting.

Ron, Where does the clutch start to grab when letting up from the floor?

A little after the middle, so toward the top. So there is some space at the bottom before it starts to grab. Does that make sense? Lol

I know your setup is pretty gnarly, any way this is a break in issue?

Joe@ZSpeed

It does but what isn't making sense to me if nothing happens in the bottom area it's released all the way and should not be causing issues.

If you just sit there for a sec after depressing the clutch does it still happen?

Mine was bled twice, so pedal pressure is good. Like Ron, we both have have the sticky gear issue still. My clutch now engages near up top now as well (nice without the extra play). Although it gets notchy at times, it's much better than before. Plus, gearbox fluid flush makes seems to have improved shifting effort as well (smoother).

Yes it still happens. I start the car, let it sit. Depress clutch all the way to the floor, wait a few seconds and go for 1st. Won't go in and have to force it. Once it is, with the clutch still pressed I can shift through all gears with no issue. Drive until I have to stop and the same thing happens.
