Clutch or Master-Slave Problem
I bought a 1984 F-250 w/ 351 & 4 Speed. The clutch does not disengage completely, especially after the truck is warmed up. I have to force it into gear from a stop and shifting is hard too. It also shifts very sloppy, have to feel around to find the gears, or wants to go into reverse instead of 4th if I'm not careful.
The Master - Slave(external) is what I have assumed is shot, although I read an article here that the pushrod linkage to the Master may be worn (I have called parts stores to try and find an adjustable pushrod, no one can find them I even have the part #)
I was going to replace the Master - Slave (which from what I understand comes togather and pre-filled and bled) and if the problem continues, replace the entire clutch pack.
As far as the sloppy shifting, I think maybe someone may have took off the top-loader shifter and not correctly installed it, or left a piece off or something. I don't know..
If anyone has any experiance with this problem, and could offer advice or maybe knows where to start so that I dont scatter out my entire tranny and stuff to find out that the problem is elsewhere..
Thanks...

Check the firewall for flexing when you push the clutch, they are known to crack and cause shifting problems. Ford sells a reinforcing plate to fix it. A search in this forum will give more details. If you pump the pedal 2-3 times and it goes into gear easy that would most likely be a hydralic problem.

Yes, I have done that already. No noticable flex or cracks although I guess that is a very common problem.
The pedal does not feel spongey. If your at a red lightyou have to push it as hard as you can against the floor, even the slightest lift the truck will go.

pretty much describes my problem and provides a simple solution if I could find the part. At least it would be a good place to start.
Would the clutch problem have anything to do with the sloppy shifting. I dont see how it would, but if I knew I wouldn't be here.. If the shifter had been removed, is there a certain position it has to be in when it is bolted onto the trans, or is it pretty much idiot proof? Maybe a missing or incorrectly installed part between the shifter and trans? Any ideas about this??

Sloppy shifter wouldnt be related to the clutch. I'd try to see how far you push the pedal in before the slave starrts to move. I'd say about 1" would be good, any more than 2" may be a prblem. Check for slop in between the master cyl and pedal.

I bought a new Master w/ adjustable whoziewhatzit, and (finally) got it all togather.. It seems to have taken care of the clutch problem so far (havent drove it but a couple hundred feet yet) but I could tell the difference already..
Now, I still have the shifter problem.. I hope It wasn't abused so much previously because of the clutch problem that it has something bent or broken inside... I am thinking maybe taking the shifter out and seeing if there's something obviously wrong or missing, but it would have to be REALLY obvious since I dont know much if anything about it..
Anyways, Thanks 4 the replies guys..
Whether I end up fixing it, destroying it, or paying a compentent person to laugh at me behind my back for whatever I did to get it into the shape it's in when I finally bring it to a pro for him to replace... I'll let ya's know...

I'm buying a 88 F250 with the exact same problem. Well I went to look at it having been told the clutch wouldn't engage and it needed a master cylinder. When I got there I tried it and it went right in gear. I drove it down the street and it works fine. I'm not sure what the problem was.
The shifter is really sloppy though. I haven't hit reverse going for 4th yet but I hit 5th going for 3rd. I'll have to watch out for that when I drive it the 40 miles home monday. My 88 250 I already have just feels a lot better. The one I went to look at the shifter just kind of hangs where ever in neutral. The one I already have the shifter springs right smack dab to the middle.

There are teflon shoes on the shifter forks that are more than like worn or missing this will cause the shifting problem.
