clutch??
I have a 94 f250 with 7.3 and zf 5speed In the past day I have noticed that the cluch peatl is engaging the cluch about 1 in off the floor and it is hard to shift in and out of gear. I cheched the fluid and its ok and the trans isnt loose from the engine, The clutch is about 1 year (50,000) miles old any ideas

you could have a problem with the clutch plate. i just pulled my motor and two of my clutch plate bolts were not even finger tite, mine did the same thing. it could be that the clutch disc is wore out also, if it was not replaced.

clutch disc was replaced, I did check where the pedal pivosts no flexing, I was kinda wondering about if it could be the slave cld or the clucth master cld and how would I check them

To check out the hydraulic system you will need a helper to press the pedal while you look at the slave cylinder. If yours is the external slave cyl. it is easy, you can see the actuating rod move as the pedal is pressed down. you can also how much free play there is in the throwout lever with no pressure on the pedal (should only be about 1/4in. or less). Rod should start extending as soon as the clutch pedal is pressed down about an inch. However if yours is the concentric slave cyl. (probably is) you will have to remove a plate from the bell housing and try to look in to see the cylinder moving. If there is no movement for a large stroke of the pedal you probably have a defective master cyl. If it was defective the slave cylinder would probably be leaking fluid. I hope this helps but even though your plate was recently replaced it does not mean that that is not the problem.

well as soon as I got done typing my dad pulled in across the street so I had him helpme out I have a 1/4 in movment so Im guessing that means every thing in the hdralic part is working corectly so that means I get to change another clutch, if so I remeber hearing it before but can I go back to a single mass flywheel insted of the dual mass fly wheel with the 5 speed?

Hold everything. You have 1/4in movement? Is this at the end of the throwout lever? You have to pull the throwout lever back against the slave cylinder rod as far as you can and then measure the free play in the end of the lever. If it is around a 1/4in. it usually means everything mechanical in the clutch is OK, including the plate. If you mean that with a full stroke of the clutch pedal you only get 1/4in movement of the slave cyl. rod then it would sound like you need a master cylinder.

OK, now you need to establish two things. How much free play is there in the clutch pedal. With the pedal fully up, press it down with your hand. Measure how far it goes down before it goes hard. It should only go down about an inch. Next see how much free play you have in the throwout lever, from pushed fully back against the operating rod to when it won`t go any further in the other direction. There should be a lot more stroke in the slave cyl. than 1/4in. So either there is too much free play in the throwout lever and the piston in the cyl. is already well out or your master cylinder has air in or is bad and not pumping enough fluid to extend the slave cylinder.
