I have an 85 F250 with 4.9l 300 six. I have just put a new clutch ,pressure plate, throw-out bearing, and had the flywheel turned. Upon trying it out i noticed the clutch would not fully disengage. I have adjusted everything there is and some there’s not…lol.
i have bled the system with no results. i have checked my receipts and found that all the parts used were the correct ones. I NEED HELP. it seems as thought there is just a hair more pedal needed. it will drive and i can force it into a gear with a synchronizer, but reverse and bulldog are a challenge. do you think they took to much off the flywheel? I’ve also heard about a cracked fire wall that allows flex? i even but a threaded bolt in the salve and adjusted it until the clutch would slip without any pedal depression. when I depressed it no change. Its like I’m on the bottom and nowhere else to go? it has to be a wrong part?

…..See you on the boards.
There are some threads about a problem with some plastic sleeve on the clutch but I have no personal experience with it. I do have a couple of ideas though. Did you compare the old parts with the new before installing? Parts have been boxed wrong before. Remember that most parts come from out of the country. The folks in that country probably can't read english. Chances are they can't read at all. Now here's the killer. Is it posible you installed the disc backwards? It happens a lot. Good luck.
that is what I was going to say. When I did my first clutch (when I was 16) I put the disc bassakwords. it wouldnt bleed, and I had to pump the clutch mutilple times to shift. I did that for about a week before I took it back apart and found out it was in wrong. GL

when i bled the clutch it just went to the floor...i had to manual pull it back up and pump till it came back...even then it was the same not fully diengaging
I don't have much experience with this problem but a few things I recall reading here that also might be it.....
Any chance carpet is too thick preventing peddle from going all the way down? SOme people add sound material or replace carpet, put in a thick mat etc that takes away a 1/4 inch or so of pedal movement. When I first bought my truck, the guy had a mat in it that would catch the gas pedal. No excitement like trying to stop and realizing your gas pedal is stuck down!!!
Also, there was a problem with firewall flex on these right at the clutch that prevented proper clutch engagement. They even build a kit to correct it.
If you can't find something simple like putting it in wrong or carpet, I would bet it is a flexing firewall.
i ran into the same problem on a 85 you can reindex the bellcrank you take he linkage apart under the dash rotate it and bolt it back on it was a PIA but it worked
