Clutch problems (basket case)
OK So far so good. Now I have clutch problems. After bleeding the clutch master and slave with the slave off the bell housing everything looks good until I go to put the slave back on the bell housing. I have to almost bottom the rod to get the slave on the bell housing. then the petal goes to the floor and stays there.
Do I have the wrong parts?
Basics:
84 F 350
93 F 150 cab
460 from who knows where. ( from the casting numbers I think it's 84 also)

Weird. You would expect that with the slave cyl removed and the clutch pedal depressed the piston would easily push out.
What transmission have you got? What master cyl are you using? Is the line connecting the two cyls stock or custom made?

It does the piston in the slave comes all the way out to the snap ring on the first push with the slave off. This is a basket case I bought so I'm not sure what master/slave. The line between is new. It acts like the rod between the slave and the fork is too long or I have the wrong fork. The fork I have is almost straight. Standard grannie four speed. (t19?).

So, it sounds like the slave cyl is operating normally when not mounted to the bellhousing. Why does it not do the same thing when in position? Bad master cyl?
With the slave cyl removed, how much free play do you have at the end of the throwout lever?

Must be like 6 -8 inches. You can see the throw out bearing moving from the pressure plate to the end of the transmission.

Well, the free play at the end of the throwout lever should be more like a quarter of an inch (at the outer edge where the slave cyl push rod attaches).

If you have zero then that must mean that the piston in the slave cyl is pushed fully in. If that is so then why does it not push out when the pedal is depressed and so disengage the clutch? As you have no play it means that the throwout bearing is against the pressure plate fingers and so any movement of the slave cyl piston should start to disengage the clutch.
It would seem like that as soon as hydraulis pressure is required, the master cyl fails. Can you see any fluid on the firewall, under the dash, where the pedal push rod goes through?
Is the fluid resevoir full (without the rubber diaphram in place)?

Good man, glad you got it working.
If you push hard both ways on the throwout lever do you still have zero play? If so you need to get a little free play otherwise you will have excessive clutch wear. If there is no play maybe shorten the actuating rod a little.
Good luck.
