I helped a friend replace his clutch in his 2004 f350 he got a valair clutch it came with the flywheel we replaced the hydraulics to. The pedal doesn't disengage the clutch till its almost on the floor and it doesn't completely disengage. The throwout bearing is new the clutch fork is good the plastic peace that holds the clutch fork is new. I can't think of any thing else that might keep it from working correctly. Any help would be really appreciated
