Question about 1994 Ford F150 Styleside Supercab
That truck is getting long in the tooth, so to speak, so I am unsure if it is a linkage activated clutch or a hydraulic activated clutch. If it is a linkage clutch it sounds like the linkage needs adjustment. You need to have the linkage adjusted just right so the throw out bearing is fully off the fingers of the clutch, but not to excess or the bearing won't throw out enough to separate the engine from the drive line totally. A good rule of thumb is no more than one inch of free play at the top of the pedal. If this is not correct it will not allow the truck to go into gear and if it does you will grind the gears because the input side of the transmission is still rotating.
One good thing about a hydraulic system is that the pedal is linked to the clutch hydraulically so free play is not required but there can be no air in the system not even a bubble or the slave unit will not deliver a full stroke to the clutch fork. This will have the same affect as the linkage not being adjusted correctly. You will need to bleed the assembly and sometimes it takes a lot of bleeding to get the air out. It is a two person job. Run some brake fluid through the system by opening the bleeder on the slave cylinder attached to the transmission. Have a helper depress the clutch pedal until it touches the floorboard. Have him tell you so you can close the bleeder.Once the bleeder is closed have your helper push the clutch pedal several times pausing 5 seconds between each push. Keep an eye on the fluid resovoir for the clutch and fill as needed. Do this untill you either remove all the bubbles or the clutch feels good again. It can take a lot of time to move the air down the pipe so be prepared.
