Got the 5 speed trans put in, new disc, pressure plate and throwout bearing. No matter how far i adjuct my clutch rod, i cant get my clutch to release. Any ideas as to what is wrong. I have installed about 100 clutches in my life time, and never had this happen. I put this s10 5 speed behind my 250 six banger, and use the Astro van 11" clutch disc. Need help bad.

Are you feeling any pressure at-all when trying to adjust it out ? You do have the disc on the right way i guess ? Could be the throw out bearing also. JMO
Wait is that a hyd clutch set-up?

The pedal is very hard to push down now, im using my old clutch pivot shaft to operate my clutch, no hydralics. I think i will have to pull the trans back out and see if i can locate the problem. I had to shorten the input shaft and the collar that the throwout bearing rides on, as everyone told me i would have to do that. So i don't know what i did wrong. Im sure i have the disc on right.

I think i found the problem. It seams that end of the splines on the input shaft are 1/8" to long, and this is causing my input shaft to bind up. I was told by a trans guy in Kansas that i need to put some 1/8" washers between the trans and the bellhousing and this will solve my problem. Is this safe to do. He said he has never had any problems doing it this way. He said my disc was disengaging ok, but could not turn my output shaft as the end of the input splines were hitting my pilot bushing when i tightened my trans bolts tight. Please let me know what you all think about this. As i dont know of any other way to fix the problem.

I cannot get my clutch to release. I have tried just about everything. It worked fine untill i installed the Astro 11" clutch disc to use with the 5 speed. I have had the trans out 3 times now, and cannot find the problem. Please someone help here. Anyone used the Astro 11" disc before with the S10 5 speed.

Sounds like the disk in in backwards or the throwout bearing angle is off. When you step on the clutch can you see the throwout bearing push the clutch fingers.

what clutch assembly did you have in before? are the pressure plate heights the same between the old clutch and the new 11" you installed? if not, im willing to bet that your having a geometry issue with the clutch fork and pivot ball.
and just a dumb question but, you did lubricate the bearing retainer and pivot ball correct?

Had a problem like that one time and the pivot ball wasn't seating in the fork properly. I had swaped forks and didn't catch the difference until the third time I put the clutch. Make sure that the ball is seated in the socket located in the fork and make sure the fork socket fits the pivot ball.

Since the only thing different is the Astro disc, I would suspect that to be the prob. Compare the old disc with the new Astro and note any dif. in hub design/dementions/thickness. Also check part No. to make sure you actually were given the correct disc.

I haven't got a clue what's up with this clutch but no one has addressed what the OP said in post #4, which I have quoted. Seems like a really strange diagnosis to me! Then two days later he comes back with this:

I have checked that my clutch disc is in right, the pivot ball is lubed and lined up correct. I have found that the splines on the 5 speed output shaft do not come all the way back to the collar that the throwout bearing rides on. On my old trans they came all the way back. My 5 speed is 1" short on the splines coming back, and i think i am binding up on the clutch disc when i install the trans. The new disc is the same thickness, and like i said THE ONLY THING I CAN FIND IS THE SPLINES ON THE 5 SPEED DONT COME BACK FAR ENOUGH. tHIS MAY BE MY PROBLEM. i HAVE TALKED TO 3 DIFFERENT TRANS SHOPS, AND THEY HAVE NO IDEA WHAT IS CAUSING MY PROBLEM, BUT I THINK I NOW KNOW WHERE TO START. Will put the trans back in wed, and will let you all know if that was the problem. My arms are getting sore from lifting this trans so many times in this cold weather, but i will solve this problem. Thank you all for trying to help me out, you all inspire me, as you have so much knowledge. We will get this fixed, as i have to get my car back together, as my only one eye i have left is getting worse, its up to 20-100 now so i am now half blind in the only eye i have left, and i am building this car for my wife so she can ride in style in her 48 chevy Cream Puff. I will not give up.

That's right never give up. And yes let us know how it goes.

Well i got my clutch to work, after pulling the trans 4 times. The problem was the splines on the input shaft were different than my old 3 speed. The plines came all the way back to the collar for my throwout bearing, but on the 5 speed they were about 3/4" shorter. I took my clutch disc to the machine shop and had 3/16" cut back on the splines this kept the disc from binding up when i tried to release the clutch. This was all it needed and now my clutch works great. I used the Astro 11" disc, and with the 3/16 taken out it made my clutch release perfect. I also has to make a 1/8" spacer BETWEEN THE TRANS AND BELLHOUSING. No ONE COULD FIND THE PROBLEM AS I WAS PUTTING THIS BEHIND AN INLINE 6, WHICH IS DIFFERENT THAN A v8 OR v6. but I GOT I TO WORK JUST GREAT.You can see in the photo what i am taking about with the splines. I hope this will help someone else if they run into this problem. And they can contact me and i will walk them through this.

well actually, between the 6 and a 307 v-8 with the same auto trans, they take the same flex-plate and starter combo. and the same setup can be used on a 4.3 v-6 as well, so that would lead me to believe the difference is in the thickness of the flywheel, or the space from the back of the engine to the face of the flywheel between the 2 motors. shame the flywheel from the astrovan wont work, cause the back of the crank is different. if they wernt, i think if you couldve used it, you would have never run into your problem.
either way, im just happy for you on getting it working.

X2 I'm glad you got it going also.
