A couple Odd things about my Clutch

Minsu · 11-22-2014, 09:47 AM

Ok so recently ive been driving around. And I havent found a solution to this burning question.

So firstly, when im not moving and i depress my clutch to shift into first, were all good.

Then once im going like lets say 14-18mph and depress my clutch it gets wierd. Heres the specific order of what happens and how it happens.

Driving up to speed to get ready to shift to second.
Depress clutch and shift into second, this is where things get wierd.
I FEEL so much feedback coming from the clutch. Like i feel this incredible vibration that i havent felt before. its not violent by any means, but its a feedback ive not felt the entire year ive been driving.

It cant be the CSC problem cause my clutch is still stronk.

And im not sure if its just cold but yesterday when i was driving as i depress my clutch, maybe 3/4 of the way down i hear a, shwink, shwink.
Hard to explain the sound, sounds like when you sharpen knives? i guess?

Sit there and say shwink, shwink, in a metallic feel.

Lol.

Thank

Don't assume you can't have a CSC problem.

Do you know anyone else around with a manual Z? Let them drive it. Don't tell them about the potential issue until after and see if they noticed.

Great Advice, my friend drives an 09z ill have him test it for me monday!
Before that what are some symptoms of maybe not enough clutch fluid?

Clutch fluid is easy to see. Look at it. If it's low you have an incoming problem since it's a closed system. If it's low there's a leak somewhere. If it's black and dirty you have an incoming problem since the black stuff in it is bits of CSC.

Notice how the clutch fluid looks darker than the brake fluid? That means the internals of the OEM CSC are starting to come apart. Right now you've got two options. One is to continue driving it until it fails, and then pray the dealer takes care of you on the warranty. The other is to buy the HD CSC now and put it on a shelf, so when it fails you can sweet talk the dealer into installing it instead of the OEM piece when the car shows up there on a flatbed.

Someone soon will chime in about the magical "GTR Fluid" that will cure all your woes. It's a band-aid. The problem is a failing part, and fluid will not save it. It will only prolong the time until the bearing fails.

I disagree. The clutch fluid needs to be changed. It is not real bad, but needs to be changed. It is normal for the clutch fluid to look crappier than the brake fluid. It needs changing more often. Been that way on every Z I have ever owned.

Show me one person who had a CSC problem solved by fluid. Solved, not put off a few thousand miles. I'll wait.

He doesn't have a problem yet, but he will if he doesn't change the fluid. All CSC will fail eventually. Even on the older Z's that were on the outside of the bellhousing, They failed too. Pisses me off because they have always had issue no matter what the brand. What did Nissan do? Go and stick the dam thing inside the bellhousing. Now they are making it a pain in the butt to change. It used to only take 10mins to change one.

Elaborate lol please

DOOMMONKEY777 · 11-22-2014, 07:00 PM

I believe the feedback ur getting is from them NOT being round, causes the csc to move slightly in and out, also causing ur clutch to move in and out and transfer these vibrations to the pedal since the csc it self is in good shape. Am a mechanical Engineer, in general that makes me think is what's happening. I could be wrong.

Minsu · 11-22-2014, 07:01 PM

Hmmm, thanks for all the advice, for those who had there csc fail did you have alot of vibrating feedback when you shifted into higher gears, doommonkey, what you said makes sense, about the bearings not being round anymore. Thank you.
