Non-s2k clutch diagnostic help needed
Hi Everyone,
I posted this in the "under the hood" section but im hoping some locals might have some insight on whats wrong with my little hoopty. its a POS car, but i love it, and if i can fix it on the cheap i will.
thanks everyone.
I need a little help with my little hoopty of a car that i putter around town in. It has some odd shifting problem that i need help diagnosing. Here's the general facts
Year 1989
Make: Subaru
Model: Justy
Motor: 1.2L 3 cyl (the big block)
Trans: 5-speed manual, push-button 4wd and a cable-operated clutch, no hydraulics
Heres the specific problem and data i can provide.
Problem: the car has an extremely hard time shifting into gear. With the clutch in at a dead stop, you can push on the gear selector with all your might and it will just make a "moaning" sound and not slide into gear. from time to time it will go into first but its quite the magic trick to do it. Initially i though that since this is such a cheapo car, it has no clutch stop and somehow the clutch was getting engaged too far causing the "fingers" on the pressure plate to engage the friction disc, causing it to spin the input shaft essentially acting as if you were trying to shift the car without using the clutch form a dead stop. I thought this, because if you lifted up on the clutch pedal ever so slightly, it would slip into gear.
I drove the car roughly 22 miles on the freeway and when i got home, i couldnt get it into gear from a stop to save my life. I managed to get it into reverse once, and with the clutch fully engaged, the car rocketed (as much as a 3 clyl can) backwards and i almost slammed into my garage door. This makes me think that the clutch is not fully engaging when the pedal is depressed.
The clutch cable is fine. It operates as it should. There's no extra slack in the cable beyond the normal free play. There is also more pedal travel that can be had. The clutch pedal has another inch or two to go before it hits the floor inside the cabin and there is no clutch stop on the pedal tree. In the event the cable stretched, id think that between the lack of a cluth-pedal-stop, and the extra potential pedal "throw", it would sort of remedy itself if it were a stretched cable.
This leads me to believe that its a broken pressure plate causing the clutch assembly to not fully engage and release the pressure plate friction surface from the clutch disc. This is why the car is acting as if im shifting without using the clutch when in i actually am.
thoughts? ideas? anything?
Thanks guys

for anyone that might have been curious heres the answer.
I pulled the motor and trans as a combo last weekend and when i popped off the pressure plate this is what i saw.

basically one of the spring retaining pieces failed and the spring was rattling around between the backside of the pressure plate and the disc. The spring actually had some flat sides to it where i presume it should be round, and the back of the pressure plate fingers/diaphragm spring release has some pretty bad wear on it too.
also something odd to note, the springs on the hub of the disc are asymmetrical about one axis. note there are 2 long and 2 short ones.
the new exedy clutch i installed had only 3 springs but they were all the same length.
