See the truck hasn't been on the road in nearly 15 years. I've never figured the issue with the clutch out. I have never driven the truck either. I'm just trying to get Otto depress the pressure plate. If it doesn't I'm going to buy a new clutch. I just want it to be able to drive in the winter for an off-road toy.
I have no idea what this means -- "I'm just trying to get Otto depress the pressure plate"???
Ordinarily, bad cab mounts don't present much of a problem.. But when they're so rusty and deteriorated so badly that the cab moves around.. If the cab moves with clutch pedal depression, it "kills" some of the linkage's ability to release the clutch.. Fix the cab mounts and I'll bet your clutch issue disappears...
If you'll permit me to use an analogy.. Suppose a truck has a broken motor mount.. Every time the truck accelerates, the engine "rears up" and the fan tears up the shroud.. A smaller diameter fan is not the solution.. Replace the motor mount and the fan no longer tears up the shroud...
