Been working on another F150. This one has the 300 6 cyl with the manual OD trans. Once I got the truck running well enough to attempt a drive I noticed the hydraulic clutch would engage / disengage right on the floor. There is no adjustment. Checked the master and slave cylinders. Master is fine slave was leaking pretty bad so I replaced it and bled it out very well. No change. Will I have to do a change out of the complete clutch set and turn the flywheel?
