1991 F150 clutch wont disengage after replacement

I have a 1991 Ford F150 i bought. Told the transmission was shot, long story short, found out it was just a bad clutch. Pulled the transmission, replaced the clutch, pressure plate, and throwout bearing. Put everything back together, now i cant get the clutch to fully disengage. Had good pressure prior to replacement of the clutch, still has some pressure. just doesn't have enough to disengage the clutch. pulled the inspection cover, and verified the slave is moving. Anyone have any ideas as to whats causing this issue? I cant tell you how frusterated i am with this thing

Throw out bearing and clutch both looked to be the same. Bought them as a kit together

I did not personally install the clutch. i took the old one out, and reassembled and bolted everything back up. A friend installed the clutch, who has done clutch replacements before. I'll have to ask him about it. Any other things that could be wrong though?

Have you bled the clutch hydraulics?

1 of two reasons.....

1. Clutch pressure plate springs have hung up or failed

2) TO bearing failed and is dragging on the shaft


that is also assuming everything else is working properly....

Ive been trying to bleed the hydraulics, but i have no idea if their fully bled or not. like i said, i do have pressure, and you can see it moving through the inspection cover, but the pedal has play before it starts to get pressure. Both the throwout bearing, and the pressure plate are new. So i dont think those would have failed. but anythings possible. Oh, and my friend who installed the clutch said he did do it right.

If there is freeplay the hydraulics are not fully bled. Bleeding can be a real PITA.
