So i am having problems with my tranny disengaing, it does not disengage at all and its not the TOB, Slave cylinder knor clutch master cylinder that has gone bad. My friend tells me the pilot bearing is bad, Is that even something the Transmission/Clutch have? What are the symptons of a bad pilot bearing?

 

if your talking about a bearing in the flywheel that the input shaft sits in (ie subaru style), evos do not have that.

However they do use a throw out bearing

 

I see, but my TOB bearing is good and disengaging fine. and its not the gear box. I will have to pull it out and see whats happening.

 

My car is doing the EXACT same thing, just happened last thursday night. I replaced master and slave clutch cylinders, have full pedal but when I try to shift it won't go into gear and will act as if the clutch is engaged already, like the pedal is up off the floor when it's relaly pushed down.

I am going to be taking my trans off the car next weekend. I have heard a multitude of things. Clutch fork broken, flywheel bolt (?), pressure plate springs, pressure plate bolt, etc...

If you find anything out PLEASE post it!!! I will do the same

 

what are your problems exactly? when you say "tranny is not disengaging" what does that mean? and what do you mean by "TOB is disengaging" neither of those should "disengage" - the TOB is locking in place and spins... it pulls the pressure plate from the clutch disk but it should always stay "engage" or you have broken your retaining clip

 

Like I stated above: I have pedal and we bled both brake and clutch systems. Clutch is acting like it's not being pulled back in order to shift.

Imagine you are sitting in your car. You are in nuetral not moving. You push the pedal down and start to shift into first gear. The shifter will NOT go into first, and the car will start moving forward very slowly as I push the shifter into first gear position. It will not go all the way in, but will fight and the car will move forward.

Make sense? I can't describe it any better than that.

*EDIT*

aaaaand I just saw that you were talking to the OP, lol. My bad. But my post remains vaild!

 

I'm gonna go with air in the clutch line. Most people think they have it bled completely, but they don't. When I got my Motive power bleeder for my brakes, I did the clutch line as well. I know it was bled properly this time because my brake pedal has never been this stiff the entire time I've had the car (over 4 years).

 

I hear you man I am in the same boat. I'm taking down my tranny to inspect is this weekend. I will let you know as soon as I pull it.

 

When car is on and I try to put it in gear it will not go into gear. It happened to me in the highway i was shifting from 2 to 3rd on 7k rpm and it would grind. Then After that my clutch did not disengage and would stay on the whole time.i pressed clutch and nothing, also noticed a lot of vibration. I had to revmatch shift the whole way home. The throw out bearing seems to be disengaging the clutch splines fine, see attached pictures of it without pressing the clutch and pressed. The clutch master cylinder and slave are both working fine and the slave is extending fine. I bleeded the system about 15 times and nothing. The clutch simply stays engaged and does not want to disengage.

 

Clutch enganged

 

sounds like you should adjust your clutch before you pull the transmission unless you enjoy all that work

 

I've talked to a few people and got a couple more ideas, none of them really good to hear, lol. Flywheel bolt on my buddies car backed out and took off some flywheel teeth. Another one is the clutch disk springs may have fallen out and are loose.

I've bled the system, I've adjusted the clutch and I am still right back where I started as well. Chances are high it's going to be something to do directly with the clutch disk/pressure plate or flywheel.

 

I have already adjusted the clutch and nothing, i adjusted it half way and bleed and then put it up how it was and bleed it again and nothing.

 

Thats exactly what i was thinking, maybe a lose bolt or something. I will bring down the tranny this weekend. If its a lose bolt Locktite blue compound will fix that . But hopefully its nothing major.

 

use red loctite on flywheel/pressure plate bolts. I think if a flywheel bolt backed out you would have way more serious problems such as pieces of a flywheel sticking through your hood... flywheel bolts coming loose is generally a catastrophic failure
