We Have A BIG Problem!!!
 
I just spent all damn day putting my tranny back in the car since the clutch fork broke a while back. I got all my parts put them in and everything went to turn on the car and was hoping for the best but knew of course the worst would happen.

Here is the thing the fork is moving a good inch+ i thought maybe air in the line so we got all of that out. When i try to put it into gear it won't let me and when i try to start the car in gear the tires start to move???? What could be wrong in need of some serious help!!!!!!!!

??? I talked to rx7.com he said maybe i put the pressure plate in backwards or possibly the piolt bearing is damaged or the clutch got damaged during installtion.

Are you sure that the throwout bearing is fully inserted into the wedge collar and it is staying connected to the pressure plate when the pedal is pressed?

It is difficult to install the clutch disc backwards, since it really only fits one way, but I guess it could happen.

Did you install a new clutch at the same time, or just the fork? If you installed a new clutch you might try adjusting the clutch pedal so you get a little more throw. Also, when you install a new clutch there is usually some "fuzz" that will wear off after a couple minutes of driving and slipping the clutch.

No i stuck with the clutch i already had in it since the clutch had 6-8k on it. I'm sure it was fully inserted into the wedge collar i checked that. This is really strange!!!

I just don't understand why it won't go into gear when the engine is running but then when i start the car in gear the tires begin to move!

I have absoloutely 0 experience with FD transmissions, but from what you describe it sounds like its just incorrectly adjusted. Possibly the cluth fork isnt moving enough to disengage the clutch? check and double check there is no air in the line, and look at how much it moves if you can...

If installed a new pilot bearing when you put the tranny back in you may have damaged the pilot bearing if you didn't replace it and used the bell housing bolts to pull the motor and tranny together then the pilot bearing may have dropped a roller and it's now wedged between the crank and input shaft to the tranny. What it sounds like is that the input shaft of the transmission is locked together with the crank and the clutch has no part of disengauging the output of the motor with the input shaft of the tranny. Your going to either have to pull the tranny and replace the pilot bearing (if you can get them apart) or (if you can start the car in gear and drive it) you need to get the car moving and (with the clutch "IN" give the car several burst of gas to see if you can get the motor to break free of the input shaft. You'll still have to pull the tranny and fix the pilot bearing, but at least you won't have to pull the motor too as it will be next to impossible to seperate them in the car. Jack

try adjusting the clutch rod out some.

unfortunately your throw out bearing is probably in backwards.

please don't ask me how i know.

I bet you that you installed the clutch disk backwards... On the FD, it's quite possible to do. The symptoms are exactly how you describe them.

If the clutch fork is moving almost an inch, that's plenty... but the disk is in backward, so it's not enough!

disc
 
Sounds exactly like what happened to me when I reinstalled my motor. The clutch disc could be on backwards. It makes it extremely hard to engage into gear. But with 1 friend and 2 commentators (read drunk friends) I got the tranny off flipped and reinstalled in 2 hours... Sorry to say, you probably need to pull the tranny again.

Using this exact statement. It would be your pilot bearing. You try to move the shifter from Neutral to any gear the rear wheels would start to spin.

With mine the bearing needles were jammed with the input shaft beacause of the way I was putting the tranny back in. You might as well order one and don't forget the oil seal.

I hope it is something as simple as the clutch disk being in backwards.

Is there any way to see if the piolt bearing is damaged without removing the flywheel?

You won't need to remove the flywheel. The tranny is going to have to come out no matter what you have to do. If the input shaft to the transmission is jammed with the needle bearings of the pilot bearing then it will be very hard to seperate them in the car. Best of luck to you. Jack

tranny
 
I agree, pull the tranny, if it is stuck a little friendly persuasion won't hurt it, just don't be too rough. When you do get to the clutch remember how you have it on, just so you don't put it back on wrong (if it is in fact that). Find the clutch section of the service manual, it should have a good picture of the arrangement of the disk. Good luck.

how can you install the throw out bearing in backwards i mean does it matter which side is up seemed like both sides where the fork sits were the same?
