Clutch Sticks when fully depressed

it suffers from to much grease in the gun

 

Truck have a PTO on it? Looks like an air cylinder so you could remote disengage clutch and engage PTO.

 

Looks like one of These .....Air Assist Clutch Servo To Me at least...!!


Maybe loosen the Bolt a Little at the Fixed End.. It May be Binding up..

 

On my 98 9400i, the rod goes from the clutch pedal under the dash, and thru a fiberglass panel just above the throttle and out to the linkage. Mine acted similar and turned out the fiber glass had cracked and worn out causing rough clutch operation similar to that. I reinforced the fiber glass with a piece of metal and solved the problem. Kind of uncomfortable laying under the dash, but it worked.

 

Totally foreign to me. The one on the truck has an air line to it so there has to be a solenoid valve and a switch or something somewhere else to make it do anything. Back end of that cylinder is definitely over tightened like @haycarter mentioned though.

 

Looks like a slave cylinder. Maybe it’s bad and getting hung up. Proper adjustment of the clutch is the first step. 1/2” -5/8” max at throw out, so that clutch brake engages, and 1/8” at forks when released. Adjust linkage if needed to get proper 1/8” freeplay at forks. Then see what you got.
