I've got a 99 F-150 4x4 with a manual tranny that I had my local Ford dealership replace the clutch in at about 85,000 miles and since then I've drove the truck about 17,000 miles and now it seems like I have 2 let the clutch out all the way before it will go. My question is is there any way I can adjust it 2 make it engage sooner? I saw on the tranny that there was a long narrow rubber plug which I took off and saw a bolt that could easily be turned. Is that an adjustment? What is it? Can I even do anything?

 

This is the 09+ forum. You will have better luck getting an answer in the 97-03 forum.

 

Your clutch is hydraulic, so there is no cable to adjust. It has a seperate master cylinder that mounts on the drivers side firewall under the hood. It has a line that extends from this master cylinder into the transmission, where it connects to the slave cylinder. When you step on the clutch, it forces fluid from the master cylinder down the line and into the slave cylinder, which then forces it to move the pressure plate away from the flywheel to disengage the "clutch". This is a simple explanation. Did they replace your slave cylinder when they did the clutch disc and pressure plate ? Did they replace your flywheel or resurface your flywheel ? Do you have a leak somewhere in the system ?

Sounds like it's worn down. To check for slippage, drive along about 45mph in 5th gear. Push in the clutch, rev the engine to about 4000rpm and side step the clutch pedal. The rpms should almost instantly drop back to the cruise rpm, if not and it takes awhile for the rpm to drop then it is slipping and will need replaced again. Usually if it is a Slave cyl/master cylinder issue, it will not fully release and either be hard to shift or grind when shifting.
