Uhh O! What happened? Flywheel? clutch? tranny?

[87CandyBlueT]

Okay Last weekend the day before i broke my left foot. I was driving my supra, as I was driving down the street(after cruising for about 50 minutes.) the traffic light was turning red, After slowing quite a bit i downshifted from 4th to 2nd. When I released the clutch the car jerked slightly and the clutch was stuck to the floor.(Slave cylider bad?) I pulled off the road because I couldn't shift or do anything. When i parked it I pulled the clutch out with my hand, then pressed it all the way down. The engine died, thought hmmm... tried to start again and a grinding noise is all I can hear with nothing else happening. Anyone else had this happen before or possibly know exactly what happened? I have been on crutches for a week now, I managed to remove the shifter, clutch cover plates, and the driveshaft. I'm getting ready to pull the tranny and see whats going on. My slave cylinder didn't look very good, could it be the cause? What is the grinding?(flywheel?/starter gear?) If anyone can help I would greatly appreciate it.

Thanks


*Edit* Oh and now I can push the clutch down and it gets hard about 2-3 inches from the floor and stops going down.

Could be any number of things from hydraulics to your clutch sticking on the spline. The grinding was probably the starter trying to spin the motor over. Best way to solve the mystery is to tear it apart and look for clues.

Hehe thats where I started. Why would the starter grind? Possible the shims came out? My flywheel looks to be brand new, it's very clean, has all it's teeth, no hot spots or anything. Hopefully tomorrow if the weather will allow it I can get the tranny out. Thanks for the reply.

Hey man, i know how it is to be down for a while and if you need any help i could see if i could swing by and give you a hand. Just lmk.

I could only offer you simple suggestions about what the problem is, but im sure everyone in here could offer some more in depth suggestions.

Good Luck.

i had a similar problem that I just recently fixed on my supra...... I didn't really have the problem with the starter like you are haveing but my clutch was stickin to the floor. What do you mean when you say that your slave does not look good ? I know when i took mine off my slave had a gash about 2 inches wide on that black rubber thing. Your problem is a little more complex than mine was but based on my short term experience with the problem, i would say replace the slave and see where you are from there. Not to mention that the slave is probably the cheapest place to start. ( i think anyways) Best of luck

Perhaps the Pressure Plate has failed in some way?
Spit out a spring and now it's stuck inside?

Bishop is right. Pull it out and find out the cause for certain.

My NA did something similar to this a long time ago... My mechanic (not the best, and is now in prison) pulled on the rubber black thing, and ripped it completely out, I went to get in and drive home, and the clutch went to the floor, didn't come up...not sure what he did to fix it, he told me he put back the black rubber boot thingy, and put more clutch fluid in? (I was a complete noob at the time, so you must excuse me )

Anyway, I'm not sure what he did, but after a couple trys, the clutch built resistance again, and for a while after he "repaired" it, the clutch would engage about 1-2 inches from the floor...as time went on, it went back to normal...hmm...

I have the same problem as well. I replaced my slave and is still happened. Well I tore it apart and the throw-out was busted (bearings everywhere). So I replaced the throwout and put it all back together. It didn't even last a full 24 hrs and the same problem came back. So I tore it down again and the snap ring that holds the hub release bearing to the throw-out came off! So I then replaced the snap ring and put the trans in for a second time. It worked well for a while besides the wierd "tinging" noise that sounded only when the car was moving. After that I went out to race and slammed the clutch pedal down and it happened again! I now tore it apart and the grove that the hub release bearing notch that the snap ring goes into sheared off! So now this is my third time pulling the trans but hopefully this helps you. Sorry for my novel!

lol - I bet you can pull the tranny in about 20 minutes by yourself now.

 

[Boosthpy]

Almost not quite lol... Its liftin it back in which is the hard part.

This happened to me a few weeks ago. Was hell to drive home with no clutch. After cleaning out the slave cylinder I still had the same problem. As I was bleeding out the system I watched the pedal fall to the floor :<. It turned out my master was leaking air in. I bought a rebuild kit for it, and it has been fine ever since.

The starter was probably grinding because you had your foot on the brake. The clutch was left unengaged (regardless of the pedal position, the slave cylinder probably had no pressure) so since your foot was on the brake, the transmission wouldn't spin. Since the tranny and engine were engaged, the starter couldn't get anything to spin up.

To start the car with the car left in gear, you have to be in 1st. Turn the starter and let off the brake. The engine/trans/wheels will all star at the same time.

I hope that made some sense.

I know what your talking about. However this is not my case. I beleive their is something wrong in the clutch/flywheel area. My slave cylinder isn't the only problem. But thanks none the less. I still haven't removed the tranny or starter I need to get in gear. I will post my results when everything is removed and I locate the problem. Quick ? off topic. Anyone know if CFX can make custom CF driveshafts? Say for a MK3?

Suprasport has got aluminum 1 piece driveshafts. Not Carbon Fiber but still good i'd guess.

I'll bet its the pivot point on the clutch fork, I had mine break the bolts that holds it down, and it did the same thing...

This is the release fork your talking about on the driver side clutch housing? If so yep I beleive thats my problem too. What did you use to repair. I want something of heavy grade where I don't have to do this again anytime soon.

Sure enough thats what it is. One of those 12mm bolts is broke off. Where did you get replacement bolts. I want a stronger grade or atleast OEM spec. bolts.

Also their are 2 deep scratches on the ends of the release fork. Should I replace the fork? Also is their anything i can do to beef up the fork.
