Can't get a break, buts that what i got!!!!!!!
 

I got my oil scavenge issues worked out finally, at about 8 pm. I it down and watched Joey Buddafouco beat up Chyna, then decide to do out and do some driving. I take 2 friends for a ride and guess what,,,,,,,,,, no clutch pedal, the pedal litteraly went to the floor and NO CLUTCH!!!!!! It was making a little grinding noise when i pushed in the clutch before, i figured it was my throw-out bearing or the actuating fork. I had maybe 10 miles with this happening, i figured i had a awhile before i had to do this though. The clutch itself has about 10K on it. How often does a clutch actuating fork break??? I would really hate to do the pressure plate and disk since they work fine. FYI its a 76 930 with 915.

I'd guess a broken cable first. if the cable is working fine, then I'd guess the release fork broke. I suppose it's possible that your release bearing let go of your pressure plate, but I'd be surprised. I'd be even more surprised if something was wrong with your disk or pressure plate.

My first thought was a broken cable, but the arm moves when the clutch pedal is push (not alot though). I really don't know what to hope for. I kinda hope its the clutch fork, but all that noise couldn't have been good on the throwout bearing. Maybe it will be something stupid like a pin or somehting. Everything was replace 10k miles ago, complete clutch, cables, all the bushings everything. That was in 1990 though, i guess i'm working out all of the bugs for the thing sitting for so long. Wish me the best of luck, BTW I am going to do cams while the engine is out, how tough are they , anyone have any experience with sc, sc sport, and 964 grind cams??? Thanks again guys

Try the cable first - it may not be moving all the way...

I'm definetly going to do a good check around before i just start taking stuff apart, i remembered about pins in the clutch cable and few other things when i read the post from you guys, thanks,
Damn , now i need to find a good excuse to the cams!!!

If the cable is still moving the arm a bit, then you probably had a major portion of the strands break ... and now the rest are still moving the arm, but MOSTLY just stretching now! If it grinds now going into reverse, and it didn't before ... you can bet the bank that the clutch isn't disengaging fully because of stretching strands!

Sounds like Warren is warning you that your problem may be as simple as a stretched cable. You can remove the engine as part of this repair, but that's about ten extra hours of work, minimum.

Yep, I had this happen, clutch cable strands start breaking and stretching, leaving you with less and less clutch actuation. They usually frey at one end or another, however I would replace with a new one even if no damage is visible. Cables are cheap and good to have a spare.

Me to then bang and the pedel went to the floor

Ok i checked everything out, the cable is in good shape, the clutch arm itself is not responding to any movement, the cable was actually hanging at the clutch end. The arm is in the forward position. I think the TO bearing is gone. Damn

You can't tell the condition of the cable by just looking at the transaxle end! The wear and breakage occurs at the point where the Bowden tube meets the body, so you have to remove and clean the cable to find out if there is damage!

There is also the possibility that the pedal shaft or hook fractured.

When you say that the arm 'doesn't respond' ... do you mean you can move it back and forth, but there isn't any resistance, as if it isn't engaged in the throwout bearing groove any more?

What happened i the cable actually came off when i pressed the clutch pedal, the actuator arm didn't pull the cable back, the arm i in the pressed position and is staying there all by itself, no return action. i am going to pull the cable out to check it any way. The clutch itself didn't slip on the way home. I think i'm going to have someone press the pedal while i hold the actuator arm back which will allow me to see what is going on, if the pedal moves and the arm doesn't, then the cable is stretching, if it both move then the cable would be fine, right??? Is that a bad train of thought??? Thanks
