The ball is easy to miss or loose.Or it may just be stuck in there.Pull off your clutch cable and take the preasure plate off.Now try moving your actuator arm.Should move freely.If not take outer rod out and check to make sure its not bent.And pull the inner rod out if you can.A magnet works or pull the actuator out and see if you cant feed a peice of bailing wire threw there and push it out.I would replace the inner rod and new bearing.Its possible the actuator is pushing the rod all the way in and then it hangs up on the back side of the clutch mechanism.Just a thought.Check he actuator bearing as well.
