Blown Clutch?

[topher_]

Hey guys, was driving last night launched my car hard and couldn't select 2nd. Pulled over and turned my car off. Car starts in neutral but I can't select gears, if I turn the car off I can select first and try start it with my foot on the clutch but it's like it's stalling. Any idea on what is wrong? Clutch is a Jim berry full Monty that I've done about 15-25,000 I'm on it

Sounds like it could be clutch..... So your saying if you try to start the car in first with foot on the clutch it lurches forward a bit but doesnt start?

Were there any noises? bangs? etc

[topher_]

Yeah exactly. With the handbrake on it lurches forward and stalls, handbrake off it will lurch and start but then you can't select gears. No noises at all, blew my box 3 months or so ago and it's different

[Dobz]

Can you select all the gears when your car is off with your foot off the clutch? You've got to determine if it's a gear selector problem or a clutch disengagement problem before anything.

[topher_]

Yep, I can select all gears with my foot on or off the clutch with the car off

[89CAL]

Does it easily go in gears when car is off?

if so I'd say its looking a bit like your clutch has had enough and let go

[Dobz]

I should've asked if your clutch pedal felt any different from before like it's gotten lighter or spongy?

[topher_]

Feels roughly the same, maybe a bit softer towards the end when I push it in but pretty much the same. When I press it though there is a loud squeak that sounds like a rusty gate being opened and closed

[Dobz]

I'm guessing that might be the pivot fork squeeking from no lubrication or is the squeeking in the cabin? Just to rule it out check your clutch pedal bracket to make sure it isn't cracked or broken. If that's intact and working properly then it's probably your clutch that's gone.

[topher_]

Was always a squeak inside the cabin but this noise is definitely coming from outside. Pretty cut that the clutch has failed after about 6 launches

Just pull the gearbox out and find out. Sounds like something serious anyway so your going to have to pull the gearbox out to fix whatever it is

I've had this happen once when down shifting in a previous car (r33 gtst) it ended up being

the pressure plate fork bending and the dampener springs coming loose.

threw a new clutch kit in and it was all sweet.

I could Select all gears with car off and not running.

Very difficult Gear selection into any gear with car running.

it sorta happens when you downshift from 5th to 4th at high rpm. but accidentally go from 5th to 2nd

read my thread, same issue, it was flywheel fusing itself to the clutch plate.. same symptoms as yours..

read my thread, same issue, it was flywheel fusing itself to the clutch plate.. same symptoms as yours..

yep this is exactly the same thing I think I described in your thread..

OP you've spot welded your clutch plate to your fly wheel, done it heaps of times with jims clutches and surprise surprise another broken a gearbox with one of these clutches

anyway put it in first, start it ( it will lerch forward but will start) put your foot on the clutch take it up into the boost zone and nail it. it will brake free.

but after that many kms the clutch could be stuffed anyway, but maybe not if you've only done 6 launches (think I read that)

the welding thing happens when you slip the clutch for too long and it gets really hot

[Dobz]

That's sketchy, how does he keep selling clutches when they do that? Sounds like the material they use for the pucks is too tough causing it to friction weld it's self to the flywheel.

[topher_]

That's f**ked. I will have a read of the thread, cheers for that. I'll be dropping the box on sunday anyway to confirm what it is

[Birds]

Definitely a clutch related problem, but don't rule out the following which are IMO more likely to be the cause:

- Clutch fork pivot ball could be worn, very common issue in all Nissans...can be replaced with a $70 Nismo item but the gearbox needs to be taken out to do it. Precursor to (and after) this failing is a fair bit of squeaking when moving the clutch pedal in and out.

- Leak in the hydraulic system, e.g. faulty slave or master cylinder.

put it in 1st and rok the car back n forth. sounds like the clutch has "welded' itself to the pressure plate. my 2cents

We finished taking the box out a couple hours ago, a picture speaks a thousand words.

That flywheel gonna be salvagable?

Id say so, the clutch melted itself to the flywheel not the other way round?

Get it machined and it should be fine. Or if your thinking about getting a new clutch consider buying a billet lightweight flywheel from NPC
